Summary: expatreader breaks AttributeNSImpl

Initial Comment:
With make_parser(), expatreader is what I get on Python
2.2/PyXML latest PyXML CVS.  It seems that after
coercing it to namespace mode, it sets up AttributeNSImpl:


from xml.sax import *
#from Ft.Xml import InputSource
import StringIO

XML = "<grammar
xmlns='http://relaxng.org/ns/structure/1.0' foo='bar'/>"

class TestHandler(ContentHandler):
    def startElementNS(self, name, qname, attrs):
        print name
        print qname
        print attrs.__dict__


##parser = make_parser()
##parser._namespaces = 1
##parser.setContentHandler(TestHandler())
##factory = InputSource.DefaultFactory
##isrc = factory.fromString(XML, "dummy")
##parser.parse(isrc.stream)

parser = make_parser()
parser._namespaces = 1
parser.setContentHandler(TestHandler())
stream = StringIO.StringIO(XML)
parser.parse(stream)



$ python broken-attrs.py 
(u'http://relaxng.org/ns/structure/1.0', u'grammar')
None
{'_qnames': {}, '_attrs': {(None, u'foo'): u'bar'}}


That should be

{'_qnames': {u'foo'}, '_attrs': {(None, u'foo'): u'bar'}}

This breaks getQNames() and other things.

Subject: [XML-SIG] Restrictions on documentation of AttributesImpl objects?
Message-ID: <200206020015.g520FVA05994@localhost.localdomain>

In 

http://python.org/doc/current/lib/attributes-impl-objects.html
http://python.org/doc/current/lib/attributes-ns-impl-objects.html

The APIs given for these objects are only the broad, non-Pythonic ones.  I 
think this leads people into an ugly, style for accessing these objects which 
doesn't take advantage of Python.  It also, incodentally, leads people to a 
nasty bug in expatreader with namespace_feature on:

https://sourceforge.net/tracker/index.php?func=detail&aid=563399&group_id=6473&
atid=106473

Anyway, is there any reason the Pythonic APIS (__getitem__, keys, get, items, 
etc.) are not documented?

Subject: [XML-SIG] new install does not work
Message-ID: <20020602014000.B5232@localhost.localdomain>

I've just installed the 4xslt suite. I went to the doc file and
ran:

$ python test.py

I listed the complete error message below. This message seems to
be directly related to the problem I am having with the CDATA
tag. 

I am also not able to use 4xslt. I tried running the script
provided with the download, and I got error messages. I have also
included these below.

Any help would be greatly appreciated.

"AttributesImpl objects implement a portion of the mapping protocol,
and the methods copy(), get(), has_key(), items(), keys(), and
values()"

seems pretty clear to me...

This probably means you got 4Suite 0.11.1.  The problems you report are ones 
that appear to affect people using Python 2.2 with 4Suite 0.11.1.  For Python 
2.2, we've been recommending 4Suite 0.12.0: still in alpha, but already with 
many important advances over the old version.

*sigh*.  Perils of posting while tired.  Though I posted both links, I really 
only paid attention to

http://python.org/doc/current/lib/attributes-ns-impl-objects.html

Which does not have the nice sentence you quote.  It also doesn't mention that 
AttributesNSImpl is derived from AttributesImpl, so people won't know it 
inherits these functions.

So I still think it's a doc problem, but I didn't state my case very well  :-)

Subject: [XML-SIG] Uche Ogbuji's integrated guide to XML processing in Python
Message-ID: <200206030115.g531Fou18571@localhost.localdomain>

Negatively inspired by Eric van der Vlists's frustrations in trying to work 
with Python/XML, PyXML and 4Suite, I started this project:

http://uche.ogbuji.net:8080/uche.ogbuji.net/tech/python/pyxml/?xslt=pyxml-guide
.xslt

I quite firmly intend to keep it up, so I would appreciate pointers, 
suggestions and tips.  I hope it will be a good resource for making people 
more productive in Python/XML and thus making it a more attractive choice than 
the many other options.

Only that I've not had the time to add that yet.  There is an open bug
in the Python issue tracker for this, assigned to me.

I posted this message on Sunday morning, and it hasn't appared as
of Monday, 11:57 est. I am guessing that the original email
with the full output of the error message was too large for this
mailing list, so I have resent it with most of the error message
cut out. 

I apologize if this is a duplicate message.

I downloaded 4Suite 0.12.2a2 and moved it to my /usr/local/src
folder. I untarred it. I ran

# python setup.py build

I included the error messages below.

I am a newbie to python, so I can't really see any reason to try
to make an alpa version of software work. I think I'll uninstall
pythone 2.1, and then install 2.1. Then I'll install 4Suite 0.11.

Any reason why I shouldn't do this?

Entschuldigen Sie bitte die Störung!

Mir ist etwas zu Ohren gekommen.
Eine relativ aussergewöhnliche Gerüchteküche,
aus der man mir ein schwerverdauliches Süppchen vorgesetzt hat,
ist der Grund meiner Mail.
Unappetitlich ist gar kein Ausdruck!
Ist es möglich auf  funktechnischem Wege(in welchen Frequenzbereichen?)
 jemanden zu beeinflussen oder zu manipulieren?
Oder sogar zu schikanieren und terrorisieren?
Unter dem Motto:"Einen am Sender?Nich ganz alleine?
Kleine Mannim Ohr?Falsche Wellenlänge?Bohnen in den Ohren?
Auf den Zahn gefühlt(Amalgam)?Mal unverbindlich reinhören?
Der Pullacher Wanzentanz?
Ist das Spinnerei?Das geht doch gar nicht,oder?
Und wenn wie sieht das ethisch moralisch aus?
Zur technischen Seite der Sache gibt es zwar Berichte und Webseiten:

,aber,das kann doch nicht sein,das soetwas gemacht wird,oder?
Eine Menschenrechtsverletzung sonder gleichen!?!
Ist es möglich,durch Präparation,der
Ohren und im Zusammenspiel mit eventuell vorhandenem Zahnersatz?
Mit relativ einfacher Funktechnik??
In diesem Land?Hier und heute???
Unter welchen Motiven?
Wo ist eigentlich die Abteilung  5 des BND und des Verfassungsschutzes?
Kann es sein,daß es Leute gibt,die dem BND/Verfassungsschutz,auf
funktechnischem Wege 
permanent einen Situationsbericht abliefern,ohne es selbst zu merken,im
Kindesalter machbar gemacht??
Werden durch solche inoffiziellen Mitarbeiter,beim BND und
Verfassungsschutz,nach Stasimanier,
Informationen von und über,rein theoretisch, jeden Bundesbürger,gesammelt?
Gibt es dann noch ein Recht auf  Privatsphere? Wer kontrolliert eigentlich
den BND,MAD und Verfassungsschutz auf Unterwanderung???
In der Mail geht es mir eigentlich um die Frage,ob es kriminellen Elementen,
aus dem Motiv der Bereicherung,oder Gruppierungen aus ideologischen Motiven,
möglich ist ,sich Wissen und Technik anzueignen,die zu anderen Zeiten,
aus anderen Motiven(Westfernsehen?),entwickelt wurde.
Und stellt der technische Wissensstand,
der der Allgemeinheit bekannt ist  wirklich das Ende der Fahnenstange dar?
Ist es denn nicht kriminellen Elementen genauso möglich,
ich sage das jetzt mal verharmlost und verniedlichend,
einzelne Personen oder Gruppen mit relativ einfachen Mitteln,
aus welchen Motiven auch immer, auszuspionieren?
Und stellt diese "Ausspioniererei" nicht einen erheblichen Eingriff in die
Privatsphäre dar? 
Ist es möglich einzelne Personen oder Gruppen,
eine Akzeptans einer gewissen Öffentlichkeit(suggeriert?),
die z.B. mit Hilfe von Internetseiten,wie zum Beispiel dem
"Pranger"geschaffen werden könnte,
mal vorausgestzt,zu terroriesieren und oder zu schikanieren,
und das in aller (suggerierten)Öffentlichkeit?Haben die Leute die da am
Pranger,
oder auf irgendeiner anderen Seite verunglimpft,oder gar Verleumdet werden,
eigentlich eine Chance zur Gegenöffentlichkeit?Ist das nicht Rufmord?
Vor einigen Jahren bin ich per Zufall auf die Seite "Der Pranger" gestoßen,
damals lief das noch nicht unter dem Deckmantel der Partnervermittlung.
Können sich einzelne Personen,oder Interessengemeinschaften,
aus reinem Selbstzweck,solcher Seiten bedienen,
um unter dem Deckmantel einer fragwürdigen Zivilkourage,
durch anzetteln irgendwelcher Hetzkampagnen,eigene,
ganz persöhnliche Interessen durchsetzen?
Können solche Seiten zur Koordination von kriminellen machenschaften dienen?
Die Frage,ist es  Möglichkeit oder Unmöglichkeit,technisch und
gesellschaftlich,
einzelne Personen,oder auch Gruppierungen,aus einer
kriminellen/ideologischen
Energei heraus,zu manipulieren oder zu beeinflussen,terrorisieren oder zu 
schickanieren,und zwar gezielt.
Zielgruppenmanipulation durch Massenmedien sind alltägliche Manipulation,
der mansich,mehr oder weniger,entziehen kann.
Wird das Recht auf Privatsphäre,schleichend,tiefenpsychologisch,
durch Sendungen,wie,zum Beispiel "Big brother",untergraben?
Sollte bei einem der Angemailten ein gewisser Wissensstand zum Thema
vorhanden sein,
wäre ich über Hinweise zum Thema froh.
Auf der Suche nach Antworten auf meine Fragen
maile ich verschiedene Adressen aus dem Internet an,
und hoffe aufkonstruktive Antworten und Kritiken.
Über einen Besuch auf der Seite
<http://hometown.aol.de/reinerhohn38259/homepage/index.html>
würde ich mich freuen.
Sollten Sie von mir mehrfach angeschrieben worden
sein,so bitte ich Sie,mir dies zu entschuldigen,
das war nicht beabsichtigt.
Der Grund für meine Anonymität ist die Tatsache,
daß bei derlei Fragenstellerei,
verständlicherweise,schnell der Ruf nach der Psychatrie laut wird.
Was auch Methode hat(ist).
Sollten Sie die Mail als Belästigung empfinden,
möchte ich mich hiermit dafür entschuldigen!
Big brother is watching you?


Excuse please the disturbance!

Me something came to ears.
A relatively unusual rumor kitchen,
from which one put forward to me a heavydigestible soup,
is the reason of my Mail.
Unappetizing is no printout!
Is it possible on radio Wege(in for which frequency ranges?)  to
influence or manipulate someone?
Terrorize or to even chicane and?
Under the Motto:"Einen at the Sender?Nich quite alone?
Small Mannim Ohr?Fal Wellenlaenge?Bohnen in the ears?
On the tooth clean-hear gefuehlt(Amalgam)?Mal witthout obligation?
The Pullacher bug wanzentanz?
Isn't the Spinnerei?Das goes nevertheless at all, or?
And if as looks ethicalally morally?

ideological motives is possible, to acquire itself knowledge and
technique which were developed at other times, from other
Motiven(Westfernsehen?).And does the technical knowledge status place, to

Is it not to criminal items just as possible, I legend that now times
played down and does nice-end, individual persons or groups with
relatively simple means, to spy from whatever motives always?
And doesn't this " Ausspioniererei " represent a substantial
intervention into the privatsphaere?
It is possible individual persons or groups, one acceptance to of a
certain Oeffentlichkeit(suggeriert?),  e.g. by Internet pages, how for
example the " Pranger"geschaffen could become, times vorausgestzt, to
terroriesieren and or chicane, and in everything (the people

Some years ago I am by coincidence the page " the Pranger "
encountered, at that time ran not yet under the cover of the partner
switching.Itself can individual persons, or communities of interests, from
pure self purpose, such pages to serve, over under the cover of a doubtful
Zivilkourage, through plot any rushing campaigns, own, quite
persoehnliche interests to intersperse?
Can such pages serve for the co-ordination of criminal machinations?
The question, is it possibility or impossibility, technically and
socially, individual persons, or also groupings of manipulating or of

everyday manipulation, from which, more or less, can extract itself.

Message-ID: <Pine.LNX.4.33.0206040042270.28469-100000@abeille3.ensta.fr>

Hi,

I'm new to XML processing, and I want to
write a python app that :

1- parse a xml config file,
2- set it's data as default's data in several wxPython
forms and,
3- could be able to write a pretty xml file with
the data set corrected by the user with the form.

For 1 & 2, the SAX API is very adapted but how to
simply print a new well formed xml file with this data ?

For this point (3), DOM seems to be a smarter choice,
but not for the first points (my parsed config file may
contain a lot of data that I don't need ...)

So what should I do ?

Unfortunately, pullDOM and SAX2DOM docs aren't complete :(

Thanks in advance,

Olivier

Hi All,

I'm using xml.dom.minidom for parsing the xml file.

Can i clone the Doument object and compare one Doument object with other
Document object?

Workaround for this is write the current Document object to a temp xml file
and write the docuent object after change into another xml file
and do file comparition using any other python file comparing module. But I
would like know can do this operation in python object level itself,
which will avoid the file operation and will be more efficient.

TIA,
Maharajan

How is this different from XInclude?

There was a good thread on XInclude on xml-dev at the end of April, but the
list archives apparently stop on April 26 and don't start again till May 1 :/
Maybe Uche has it. It also came up on xsl-list in the last few days.

FWIW, 4Suite's XML readers expand XIncludes by default, if I'm not mistaken.

Seems like it wouldn't be too hard to do with a SAX document handler.
Just customize startElement()...

You could try copy.deepcopy, but you are somewhat at the mercy of the
DOM implementation - this likely won't work.

You can easily avoid the file operation by writing to and reading from
a string object.

Subject: [XML-SIG] utf8 conversion issue
Message-ID: <3CFD0D1B.4080409@ag.com>

I recently discovered in PyXML 0.5.2 (more than a bit behind, I know) 
that xml.unicode.utf8_iso.code_to_utf9() is returning incorrect values. 
For example, the name "t&#xf8;rv&#xe5;ld" does not convert properly; it 
*should* be "torvald" - the 'o' with a stroke, the 'a' with a ring 
above. However, it gets mangled into "t\xc3\xb8rv\xc3\xa5ld". I took a 
look at code_to_utf8() and noticed that it in turn calls utf8chr(), 
which does a comparison to see if the ordinal passed in is <128. 
Shouldn't it be <256??? Has anyone else wondered about or experienced this?
Also, I noticed that the line doing the actual conversion reads "return 
chr(0xc0 | (c>>6)) + chr(0x80 | (c & 0x3f))" where c is the ordinal. I 
almost hesitate to ask, but why is it even necessary to bit-or and 
-shift? Especially when this seems to yield incorrect results? Am i just 
missing something?
Any input is greatly appreciated.

Do you mean _to_utf8 here? If not, what exactly is utf9?

> For example, the name "t&#xf8;rv&#xe5;ld" does not convert properly;

This is certainly different from "torvald".

> However, it gets mangled into "t\xc3\xb8rv\xc3\xa5ld".

That is correct. In UTF-8, LATIN SMALL LETTER O WITH STROKE
is /xc3/xb8, LATIN SMALL LETTER A WITH RING ABOVE is /xc3/xa5.

> I took a look at code_to_utf8() and noticed that it in turn calls
> utf8chr(), which does a comparison to see if the ordinal passed in

No. If all characters below 256 would stand for themselves (as single
bytes), how precisely would you encode characters above 256?

In UTF-8, characters between 128 and 2048 are encoded as two bytes.

> Has anyone else wondered about or experienced this?

Not with this specific implementation of UTF-8, but certainly with
other implementations of UTF-8.

> Also, I noticed that the line doing the actual conversion reads
> "return chr(0xc0 | (c>>6)) + chr(0x80 | (c & 0x3f))" where c is the

Because that's how UTF-8 is defined.

Most definitely.

Either I'm missing what the problem is, or you're missing the fact that the
results are correct. :)

Read up on UTF-8. It uses 1 byte for the ASCII range (U+0000 through U+007F) 
only, and it's a direct mapping (U+0020 --> byte x20). It uses 2 bytes for 
U+0080 through U+0FFF.

Bytes C3 B8 are exactly what you want. That is, &#xF8; means Unicode character
number F8 (in hex): LATIN SMALL LETTER O WITH STROKE. In UTF-8 this character
is represented as 2 bytes: C3 B8.
http://www.eki.ee/letter/chardata.cgi?ucode=00f8

"\xc3\xb8" is Python's unambiguous way of representing an object of type
string that consists of bytes C3 B8. Python's non-Unicode string objects are
just byte buffers, and you don't know what encoding they actually use (i.e.,
you don't know how those bytes map to Unicode characters). 

The string actually has the right bytes in it. When you print the string,
you're serializing those bytes to an output device. Depending on how you do
it, you'll either write the raw bytes to the device, or Python will do some
escaping for you, if it thinks you might need to keep the output bytes all in
the ASCII range.

Initial Comment:
Each time I (have compiled and) have installed the 
PyXML 7.1 in the python 2.1 directory (built-in with Zope 
2.5.1) the product LDAPUserFolder 1.x stopped to work.

When I want to access my LDAPUserFolder objects 
with the ZMI, Zope asked me to reauthentified then 
refused me access to the folder where these objects are 
placed.

I use a Zope 2.5.1 (python 2.1.3)
My Zope site contains only one custom product :
LDAPUserFolder 1.5

Subject: [XML-SIG] Switching back and forward between SAX and DOM
Message-ID: <3CFE87A9.7020407@dyomedea.com>

Just a Python newbie question to try to find my way into XML processing 
with Python :-)

In Java, I like to use both SAX and DOM (I prefer using SAX to bind 
documents to and from predefined data models and DOM when manipulating 
documents) and I need|want to do the same with Python (I am currently 
using Python 2.2 with 4suite 0.12 latest CVS).

How can you get a DOM tree out of SAX events (if for instance you've 
developed a ContentHandler, can you retrieve a part of the document as a 
DOM tree by forwarding the events to a DOM parser?) and vice versa, how 
can I serialize a DOM tree as SAX events which can be processed by a 
ContentHandler?

Thanks

Eric

Summary: SOAP.py detects error in PyXML-0.7.1

Initial Comment:
When I use SOAP.py (e.g. from SOAPpy097) with 
PyXML-0.7.1, I get an error.  The trace-back is below.

If I rename the _xmlplus directory under 
/usr/local/lib/python2.2/site-packages, then the error goes 
away.  I guess a default implementation of pyexpat in 
Python 2.2.1 is being used.

If I re-install PyXML-7.0, there is no error.

Note that if I attempt to fix the offending call by changing 
line 233 in expatreader.py from:

  self._parser = expat.ParserCreate(None, " ", intern =    
self._interning)

to:

  self._parser = expat.ParserCreate(None)

then I get another error, a bit farther down the line, which 
indicates that PyXML-0.7.1 is handling namespaces in a 
way that SOAP.py does not expect.

I am using Python 2.2.1.

Are there any notes on how to upgrade client code in 
order to adapt to PyXML-0.7.1?

Depends on whether you have PyXML, or only Python proper. With
minidom, there is xml.dom.ext.reader.Sax2, which takes a SAX parser;
for PyXML, xml.dom.minidom.parse does the same thing. Notice that, in
both cases, you need to pass an XMLReader. For minidom, the content
handler that will build the DOM tree is xml.dom.pulldom.SAX2DOM
(unless you need the pulldom functionality itself); for 4DOM, it
is xml.dom.ext.reader.Sax2.XmlDomGenerator.

> how can I serialize a DOM tree as SAX events which can be processed

For PyXML, xml.dom.ext.Dom2Sax does that. In standard Python, that
functionality is not available.

Notice that you will have to experiment, and might find bugs, since
that functionality is rarely used.

Martin

The basic infrastructure for both tasks is available, but largely not ported 
to the Domlettes, which I know you're using.  They use the older interfaces 
that you struggled with at first.

I'll do a bit of checking today to see how much porting would be required to 
get what you need.  These would actually be very good general-purpose 
additions to Ft.Xml.Util, and updates to xml.dom.

Well, I should have known Martin would have it all offhead  :-).

It is pretty much as I'd thought.  I don't recommend that Eric switch to 4DOM. 
 Not only has he already survived one traumatic switch, but it is a great step 
backward, not least because 4DOM is excruciatingly slow.

I'll look to updating xml.dom.ext.reader.Sax2.XmlDomGenerator and 
xml.dom.ext.Dom2Sax to general-purpose utilities for both PyXML and 4Suite 
domlettes.  Should go pretty quickly if I end up in enough boring sessions 
here at XML One  :-)

Subject: [XML-SIG] converting rtf to xml
Message-ID: <20020606123745.A4356@localhost.localdomain>

I am struggling to get a java utility called majix to work. This
utility is supposed to convert rtf files to xml.

I was wondering if there is any similar python utility? 

I have just discovered (last night!) that rtf files are
relatively structured. I'm sure I could write a crude script to
convert them myself, but I don't want to re-invent the wheel.

Thanks

Paul

<ot>Heh, I've once written a parser in C++. I can tell you that are some
very obscure corners wrt. to stylesheets and graphics.</ot>

The first thing I'd do is fire up Google:

    Searched the web for rtf2xml.   Results 1 - 10 of about 3,340.
    Search took 0.10 seconds.

Maybe this helps.

Another approach: use the RTF parser in mxTextTools or simply
use COM to have Word generate HTML which you then pass through
mxTidy to generate XHTML.

Subject: [XML-SIG] 4xslt not installed?
Message-ID: <20020607014419.B1888@localhost.localdomain>

I just did a new install of python 2.1.3, of PyXML .7, and of
4Suite. 

I then included this line in my script, in order to test things.

import Ft.Xml.Xslt 

ImportError: No module named Xml.Xslt 

However, if I use:

import xml.xslt 

then I get no error message, which means that python is using the
pyXML xslt rather than the 4Suite version.

There is an executable in /usr/local/bin. If I type ./4xslt, then
I get the standard message, telling me to enter options, so this
executable appears to be working. However, I can't figure out how
to use it from the command line! I am used to the xsltproc, where
I simply type

xsltproc stylesheet.xsl document.xml.

Any tips would be appreciated.

Paul

What version of 4Suite did you install? Unfortunately, 0.11.x and
earlier don't work with PyXML 0.7. That incompatibility could account
for your import error.

> import Ft.Xml.Xslt 

Should work for 4Suite 0.12 series. Earlier versions spelled it
as xml.xslt.

Actually, I think xsltproc is backwards. Every other XSLT processor
I know of, including 4XSLT, does it:

  <xsltcommand> document.xml stylesheet.xsl

For 4Suite, if you want to specify an output file, you can use the
-o option:

  4xslt -o foo.html document.xml stylesheet.xsl

or use a shell redirect:

  4xslt document.xml stylesheet.xsl >foo.html

To pass a parameter, you can use one or more -D statements:

  4xslt -Dcolor=red -Dstatus=fubar doc.xml style.xsl

Hope that helps a bit.

I installed 0.11x because I was told that 0.12 had a bug with
python 2.2. So I assumed I had to install python 2.13, then
install 4Suite 0.11. 

I read the README when I installed PyXML, and it said that there
could be a conflict with Xpath and Xslt in the PyXML suite, and
and Xpath and Xslt in the 4Suite. The solution, it said, was to
build like this:

python setup.py build --without-xpath --without-xslt 
python setup.py install --without-xpath --without-xslt 

This is what I did.

I enter 

$ 4xslt test.xml test.xsl

I get an error message, which I included below.

Huh?  Who said that?  I said that 0.11.1 is what has a bug with 2.2.  0.12.0 
works just fine.

Yes.

Then I'm not sure why you're having an import problem.  I certainly can't 
reproduce it.  Is there any other info you can offer?

This is the clash between 4Suite 0.11.1 and PyXML 7.1 that was pointed out.

OK.  This is probably more complex than it should be, but here it is in a 
nutshell.

*either* use

Python 2.1 + 4Suite 0.11.1 + PyXML 0.6.6

*or* use

Python 2.0, 2.1 or 2.2 + 4Suite 0.12.0 + (optionally PyXML 0.7.1)

Clear?

Aren't there outstanding issues with 2.2 on Windows, with any version of
4Suite? Or did those all get fixed?

Not for me. I had a new install of python 2.2 and of 4Suite .12. I posted on this board really got no solid anwers as to what I should do, so I decided to install the more stable (not alpha) version, .11.

No. Everyting is brand new in my install. I built python 2.13 two days ago. I downloaded PyXML .7 and built and installed this yesterday, as I did with the 4Suite. 

This is very frustrating for me. I switched from perl to python because everyone said python was great for parsing xml. Xml.com calls it "charming python," but so far it has proved about as charming as a broken car. I keep downloading the newest versions of the libraries, building them and instaling them and keep getting errors. I haven't gotten Sax or 4xslt to work.

Thanks for your patience.

All of these are fixed, except for Windows and Python 2.0

Subject: [XML-SIG] DOM performance?
Message-ID: <87bsalucb6.fsf@nwalsh.com>

Hello world,

I've been meaning to learn Python for ages and I've finally found the
project that I'm going to use to do so: a little UI thingy with an XML
back end. Ok. so I grabbed PyXML 0.7.1 and installed it on my Linux
box where I've got Python 2.1.

Running a little test program to build a DOM tree (baby steps, to be sure):

import sys
from xml.dom.ext.reader import Sax2

# create Reader object
reader = Sax2.Reader()

print "parse it!"

# parse the document
doc = reader.fromStream(sys.stdin)

print "parsed!"

I'm concerned about the performance. For a small XML document it works
fine, but for the actual 1.4Mb XML document I need to read for my
project, performance is abysmal (after several minutes, I gave up).

Am I doing something obviously wrong?

                                        Be seeing you,
                                          norm

Subject: [XML-SIG] Nastiness in xml/extensions/pyexpat.c
Message-ID: <200206081540.g58Feag19848@localhost.localdomain>

The following simple program dumps core currently.


from xml.sax import *
from xml.sax.handler import feature_namespaces
from xml.dom.ext.reader.Sax2 import XmlDomGenerator
from Ft.Xml import cDomlette

handler = XmlDomGenerator(implementation=cDomlette.implementation)

parser = make_parser()
parser.setFeature(feature_namespaces, 1)
parser.setContentHandler(handler)
parser.parse("test.xml")

doc = handler.getRootNode()

Uncommenting the line "parser.setFeature(feature_namespaces, 1)" stops it 
doing so.

In tracing the through xml/extensions/pyexpat.c (and a tremendous fag that 
was), I found an instance of sheer nastiness:

static void
flag_error(xmlparseobject *self)
{
    clear_handlers(self, 0);
}

This function doesn't really do anything to "flag" an error.  It merely clears the handlers.  The problem is that in most cases the code just continues on, and then it dumps core the next time it comes to invoking a handler (jump to address 0) since all handler pointers are now NULL.

How we handle this in cDomlette is to have a full-blown state machine.  We leave handlers untouched on error, but we have them all do nothing on error state.  This would probably be overkill for pyexpat.so, but we should at least set an actual flag on the parser instance that can be used to short-cut execution on error, and move the clear_handlers() invokation to a safer spot.

It turns out that the direct cause of the bug is that I didn't call initState() on the XmlDomGenerator instance, which eventually caused an AttributeError exception in the startPrefixMapping callback, which caused a null return to the low-level StartNamespaceDeclHandler in pyexpat.c, which invoked a flag_error() which cleared the handlers without stopping the parse, which caused the NULL address violation when the subsequent StartElementHandler was invoked.

The following code works as expected:

from xml.sax import *
from xml.sax.handler import feature_namespaces
from xml.dom.ext.reader.Sax2 import XmlDomGenerator
from Ft.Xml import cDomlette

handler = XmlDomGenerator(implementation=cDomlette.implementation)
handler.initState()

parser = make_parser()
parser.setFeature(feature_namespaces, 1)
parser.setContentHandler(handler)
parser.parse("test.xml")

doc = handler.getRootNode()


So the question is, how do we make the handling of the startPrefixMapping exception less confusing and drastic.  I have ideas, but I only dimly understood pyexpat.c, and these would invariably be hacks.

Yeah.  You're using 4DOM.  Very thorough, but very slow.  You can get much 
better perfoamnce by using a different DOM implementation

Option one: using the software you've alreasdy installed.

Use minidom instead:

import sys
from xml.dom import minidom
doc = minidom.parse(sys.stdin)


Option two: Even faster, but requires additional software.

Install 4Suite 0.12.0.  Preferably a recent CVS snapshot.  Then use cDomlette

import sys
from Ft.Xml.Domlette import NonvalidatingReader
doc = NonvalidatingReader.parseStream(sys.stdin)

do you happen to have any benchmarks available that
compares 4DOM with minidom and cdomlette?

just curious-ly yrs /F

Someone (ALexandre?) posted some startling benchmarks last year.  Does this 
list have a good searchable archive anywhere?  Google wasn't helpful in my 
quick try just now, and I've never been able to get much use out if the ASPN 
UI.

Hmm.  I looked back and saw a message from you on 6/3 with no responses.  I 
apologize.  I was mobilizing for a conference then.

I'll go back and see what I can do.

Yes.  I learned how frustrating the current state of things is for new users 
from the experience of a recent newcomer from Java/XML.

All I can say is that I personally have pledged to put work into makign things 
better: in terms of documentation and code, as time allows.  It is a pretty 
high priority for me now.

If you're a bit patient with PyXML.  I think we'll not continue to disappoint you.  And you are helping make things better by offering specific complaints.

No, this is fine.  But you also must then revert back to PyXML 0.6.6.

You'll also need to change the way you specify empty namespaces and prefixes 
once you do move to PyXML 0.7 or 4Suite 0.12.0.

Weird.  is STRING_TYPES for some reason not defined in your local copy of 
Ft/__init__.py?  (should be near the top).

At any rate, you can skip the long build-docs phase by using

./setup.py --skip-docs install

The combination of these two errors makes me think you somehow got files 
confused or corrupted.

See if

./setup.py --skip-docs install -f

(the -f meand force overwrite) helps.

You might want to rm -rf Ft and _xmlplus from your site-packages before 
trtying again.

Thanks for your response. I know that the open-source software
counts on dedicated people. 

I think things might be in a bit of a flux right now for PyXML
and 4Suite. (I understand that these two libries would eventually
merge?) I'll try installing version .6x of PyXML like you said.

I assume that first I should manually remove
/usr/local/lib/python2.1/site-packages/_xmlplus?

Thanks

Can you rephrase this example to only use PyXML (or perhaps even to
only use the expatreader)? I cannot reproduce the crash; I don't have
test.xml, and I don't have cDomlette.implementation. I modified the
code to ignore cDomlette.implementation, and took an arbitrary
document, and got a traceback ending in

which appears to be unrelated to the current problem.

It does not have to flag the error. When it is called, a Python
exception has been raised, so when it gets out of expat, the Python
exception is propagated.

Why does it crash? I.e. why does anybody invoke a NULL handler? Expat
always checks whether a handler is set before invoking it.

I need to understand the problem first, too.

Hi

I visited the websites, studied the docs, then set about bringing
everything up to date on my  Redhat 7.2 Linux box.

After getting the new python 2.2.2 installed, I found the print
spooler no longer worked - python errors. I installed the python
from RPM

I really do want to get this stuff (python, pyxml, 4thought) going
but I just gotta have printing. 

Any ideas anyone?

Not that this is in any way related to the XML-SIG. Assuming you didn't
completely blow away Python 1.5 (the version that came with Red Hat
7.2), just go into /usr/share/printconf/util/prcintconf_backend.py and
change the first line from #!/usr/bin/python to #!/usr/bin/python1.5,
restart lpd by hand (run /etc/init.d/lpd start) and fix any other small
errors that appear (I don't think there are any others).

If you didn't keep Python 1.5, download source rpms of all the required
packages printing packages from rpmfind.net and start rebuilding against
the new python. It will take a few hours, but it's certainly possible
(I've done it before).

I recommend to reinstall the Python 1.5 RPM (with force), then install
the Python 2 RPM included in your RedHat release (I believe there is
one, although I'm not sure).

If you absolutely want to install Python 2.2, you could either install
it into a different prefix (say, /usr/local), or install with "make
altinstall" (this will create /usr/bin/python2.2, but not
/usr/bin/python).

So could it be a clash between cDomlette and PyXML?  I find this hard to 
believe, or perhaps just understand.  The crash I see manifests itself long 
before it gets near any cDomlette code.

This is what is fixed by the initState() call.

The "when it gets out of expat" is the key phrase here.  From what I see, the 
entire problem is that it is not getting out of expat quickly enough.  I.e. it 
is going from the NSDecl handler to the StartELement handler without checking 
in the meantime for the global exception flag for early exit.

I suppose I'll have to narrow this down further.

Does anyone know how to get DDD to load symbols for an so that has not yet 
been loaded?  This would have helped yesterday as well.

Not in the code I saw from the core dump stack trace.

I guess I have some more work to do in tracing this...

I think it is possible to set a breakpoint on "shared library events",
but I could not figure out right now how to do that. What helps is
calling dlopen, such as

(gdb) p dlopen("/usr/lib/libjpeg.so",2)
$9 = 135696400

The 2 is RTLD_NOW on Linux.

Should that be from Ft.Xml.cDomlette? 

And is there a way to instruct 4xslt to use the cDomlette parser by
default?

Thanks!  Cheers,

cDomlette was made the default some time last month.

I suggest not explicitly using cDomlette anymore, in order to make your
code more portable.  If it's on a platform on which cDomlette is
supported (UNIX, Windows, OS X so far), it will be used.

My Windows configuration :

My Linux configuration :
Debian 2.2 + Python 2.1.3 (source distro) + pyXML 
0.7.1 (source distro)

In both cases, the xml file is parsed from the local file 
system.

another "strange" thing : the parser finds the DTD but 
not the system entities (all in the same directory).

Linux : /home/glt/xresources/main.xml
Windows : C:\Mes Documents\xresources\main.xml

Don't hesitate to contact me if you need more

hello.
I know some python and some xml and I have been playing a bit with
PyXML.
I want to get a deeper understanding of all the stuff (dom, sax, how
parsers
work).
Can you give me some advice where to start when I want to understand the
sources.

I bought two books about Python and XML (one from Oreilly and the other
is "definitive xml development" from prentice hall) but I have not read

If you mean a "Guide to the PyXML and std. Python XML
sources" you won't have much luck! I don't know the PH
book, but I translated the O'Reilly one into German
and while I think this is a really useful book I don't
think it will help you that much with understanding the
lower level package structures. Being an intro to XML
with Python it was most likely not the authors' goal
and that's ok.

If you poked already in the code here and there and have
reached some decent frustration, I know what you mean.
Other people might disagree, but I think at the moment
one must poke around a bit if one really wants to under-
stand what's going on and how some things really work.

The best advice I can give is actually to get started,
maybe looking sometimes into the test suites, although
this will not always suffice. 

After just checking the XML-HowTo it seems to me like 
it was expanded significantly over the last months,
which is good. I'm not sure how much people here like 
Wikis, but that could be a way to collect people's Py-
thon/XML experience, snippets and sugestions for im-
provements, maybe, unless they already exist?

While speaking of improvements... would anybody with the
right permissions mind to add a link to pyRXP on the 
following page:

  http://pyxml.sourceforge.net/topics/software.html

saying something like this:

"""
<tr>

I recommend you pick an API which you already know from the
application level (e.g. SAX, DOM, XPath, xmlproc, ...). For that piece
of software, you take some example that uses this API. For that
example, you

1. find out what modules it uses, by printing sys.modules.keys() after
   all imports are done, and
2. put strategic print statements into those modules, to find out who
   calls what.

I won't disagree.  In fact, I'll be rougher:

	The PyXML package is currently too difficult to understand.

Generally when doing XML work I just give up and use the smaller XML
package included with Python, and updating the HOWTO in May reinforced
this.  The problems:

	* There are too many ways to do things, and no guidance about
	  which to use.  Parsing an XML document?  There's qp_xml.py,
	  pulldom.py, SAX readers, DOM readers, xmllib, pyexpat?
	  Printing an XML document?  sax/writer.py or dom.ext.Printer?
          What's the difference between these choices?  Which ones are
	  deprecated?  

	* Some things, such as XSLT are simply broken; they don't work
          at all.  (Or maybe it'll work if I installed 4Suite; the
	  README currently says you shouldn't install the xml.xslt
	  package from PyXML, though.)

We really need to do better, but it's not clear what to do.  
Is it simply a documentation problem?  Perhaps.  But we *must*
do something about this.

The online Python Cookbook has an XML section; Uche has also started a
collection of processing tips.

Of course I'm strongly biased, but the wiki idea is the right thing. I 
could easily set up a dedicated PyXML wiki, or help create one on the 
www.python.org servers. A wiki would certainly help to focus the little =

time slices most of us have into _one_ set of docs, and enable co-
operative efforts.

Since people tend to talk about things they use, this would also mean 
that only things in actual use would be documented, allowing newbies to =

focus on exactly those things. What we already have (how-tos etc.) can 
be linked to easily.

The DocBook wiki grows rather fast currently... :)

... and speaking for myself, I *would* like to see something happen.
I think better documentation would be a good start.

I'm not a contributor for any of the code, but I have struggled to
figure out how to use some of it :-) and would be happy to assist in a
documentation effort if someone had a use for me.

Cheers,

I think this is a good idea, as I mentioned in my Advogato diary.  Well, =
I =

mentioned a 4Suite wiki there, but I also like the idea of a general =

Python/XML processing Wiki.

One of my tasks this evening is to install and get familiar with MoinMoin=
 on =

the path towards this.  You could probably tread this path much more quic=
kly =

than I could.  Why wait for an authoritative location at python.org?  I t=
hink =

it shuld not matter where the wiki is hosted as long as the various proje=
ct =

pages refer to it.

Is there documentation of which DOM methods are implemented in the current version of cDomlette (I'm using 0.4.11 with Python 2.2) and which methods may be added in the future? 

One convienient method, getElementsByTagName, isn't present. Are there plans to do this sometime in the near future? Is there a substitute?

Notice the difference: I would not mind something happening, either,
but I won't act (except by integrating patches that other people make,
and releasing the package).

Just write documentation that you thing would have been useful for you
if it had been available while you struggled. I would personally
prefer it it went either into the howto or the reference manual, but
if you think another form of documentation is more appropriate, please
go ahead.

You can use XPath which will allow you to get a more precise control of
the search. 

Assuming doc is a cDomlette document, you can use

from Ft.Xml.XPath import Evaluate
nodes = Evaluate('//tag',doc)


Or if you only want the 'tag' nodes that are children of the root
element (and not all 'tag' nodes in the document):

nodes = Evaluate('/*/tag',doc)

which will be much faster (since it avoids searching the whole tree).

Not it won't. I've put back 4XPath in the Debian python-xml package but
the 4XSLT is not there because it does not import, unless you have a
very old 4Suite installation available. My understanding is that this
will be worked on and fixed once 4Suite 0.12 is available. 

As a sidenote, I'm currently working on a Python+XML tutorial for
the Europython conference. I'll be happy to contribute the slides to a
documentation.

Great! If you still accept some feed-in: I'm especially in-
terested in the following packages (like everybody else, 
I guess):

- standard Python XML 
- PyXML
- 4Suite

evaluated using the following criteria:

- borderlines
- overlap
- dependencies
- versioning issues
- future unification

Logilab has a small contribution to the effort :

	ftp://ftp.logilab.org/pub/talks/python-uk-2002.pdf

The PyXML tutorial Alexandre Fayolle presented at the 1st Python UK
conference back in april. Part of the info is already covered in the
Howt, I think.

Stay tuned for a nicer/longer one he is preparing for EuroPython.

Hmm, not so sure. This is a tutorial, so the main thing is how to use
it, not a comparative analysis. 90 minutes is quite short to cover SAX,
DOM and XPath with detailed examples. 

I have a few words about "overlap, dependencies, versioning and
unification", but I'm not planning on giving a full lecture about the
history of PyXML and 4Suite. As for Jython, I have zero experience on
the beast, so I was not going to speak about it. I imagine that xmlproc
should run fine on top of it, since it pure python. Now, if you want to
submit a few slides (2-3 max) about PyXML and Jython, I'll be happy to
include them in the tutorial (and to give you credit for them, of
course).

That's a really good point. It's certainly easiest to use xml.dom.minidom to do 
any work with the DOM, and that might suit most people, but then there's the 
issue of using alternative DOM implementations. Although I'm sure it's 
documented somewhere, I don't think it's that obvious how to write generic code 
which can make use of other implementations, such as pirxx, for example. 
(Please prove me wrong!)

I haven't dared to do anything with XSLT in Python, but then it can take some 
motivation to do things in XSLT at all. ;-) However, I am very impressed with 
the XPath implementation.

It should be clearer how the following things can be done with PyXML:

  * Opening existing documents using SAX and DOM, using different
    implementations. (The "how to" only used to cover SAX.)

  * Creating new documents using DOM. Does one instantiate a new
    xml.dom.Document object, call methods on the DOM implementation?
    What about all those arguments to createDocument in 4DOM?

  * Serializing documents - what's the best way? It's tempting to
    use xml.dom.ext.PrettyPrint, but it doesn't always work
    properly (search for bug reports on SourceForge) and it might
    not be as fast as the 'toxml' method, but is the 'toxml'
    method standard or an extension?

  * Manipulating document nodes. It's always possible to refer
    people to the DOM specification for this, but then PyXML is
    all about a Pythonic version of the DOM. Moreover, the W3C
    specifications can be too heavy for the unseasoned
    developer.

The Pythonic DOM standard really needs specifying in full. For example, there 
are some odd differences in the implementation of the special 'attributes' 
attribute between minidom and 4DOM, in my experience. Which one is correct? 
Must I always have to check the types and take evasive action?

This seems to be a big, recurring thing with PyXML, even though I've been 
reasonably lucky never to have had problems with version conflicts and broken 
features. However, I'm surprised it's even been possible for any books on XML 
processing with Python to be published because of this.

A PyXML API accessing JAXP would be nice, but I fear that the PyXML API isn't 
formal enough (unlike the DB-API accessing JDBC, as done by zxJDBC).

4xslt works on my system - 4suite 0.11, Python 1.5.2 and, as I remember,
Python 2.1.  Can't say about Python 2.2. I found a few bugs which I posted
about some months ago.

I use 4xslt with Zope and it works very well.  I wrote an Zope External
Method to send a string of XML to 4xslt and get the transformed result back,
which then gets displayed.  This is great because the xslt processor doesn't
have a new process started each time it is called.

Which 4xslt is that? 4Suite's or PyXML's? The order of installation
does matter if I recall correctly (it's a *long* time since I used
4Suite-0.11), and there are some weird cross dependencies in the two
packages.

Correct, although I ask myself from time to time whether I should do
that even before 4Suite 0.12 is avaiable.

I completely agree that there are problems with the version
conflicts and with documentation. I also bought the O'Reilly
book (*Python & XML*). I find this book straightforward, but 
too short. For example, it handles xslt processing in around 20
pages, when it really needs to be covered in 800. 

(I have the Kay book on xslt processing called  *Xslt*, which is
literally 800 pages long and one of the best books on computers I
have bought.)

I think this thread on the lack of documentation is really a good
sign. Whether or not python suceeds in becoming a tool of choice
for prcessing xml (I'm not sure how mainsteam it is right now)
depends on readable documentation. 

In fact, good documentation is so important for all software and
all platforms. I use linux, and I am absolutely frustrated at
the terrible documentation. I often stugle with a problem for
days before finding that the solution was simple--but
undocumented, or poorly explained.

I think one reason why java is the choice for processing xml is
that you can find good, readable howtos. Sun has made sure of
this. 

On this note I would also be willing to write and submit
documentation. 

On another note, I switched from perl to python because of what
I read, which generally deprecated perl for xml processing, but
praised python. In fact, there is a series of tutorials on IBM
(I beleive), which called "charming ptyhon." I think processing
xml with  python can be "charming," but only if it is easier to
use. On the other hand, I find perl also to be kind of a mess in
regards to xml. Perl is really not a class language, and there
are so many different libraries written for xml, that I couldn't
figure out which to use.

I installed Pyxml first.  Then I deleted the xslt and (I think there was
one) xpath directories.  Then I installed 4Suite.  IIRC, you really do want
to delete the pyxml directories first, as well as any earlier FT
directories.

Just to make a note: I don't mean to make my separate efforts at documentation 
mto detract from the HOWTO or reference manual.  In fact, I expect to migrate 
all the appropriate items to these standard docs soon.  My approach is more 
collation and annotation than brand new documentation.  I think is the 
shortest path to getting some of the recent thoughts in one place.

That was always the moment of pain with Wikis for me.

I think few of them are designed in a way that would 
make it easy to save a page in "cleaned-up, standalone" 
HTML, that can be easily plugged into some other HTML
"environment". For me that means there should be no 
more styles, images, etc. which could conflict with 
the target environment.

On the long run I'd even advocate for an option to 
condense an entire Wiki space into a single PDF file,
hyperlinked like hell, of course. ;-)

But,-well,-on-the-long-run-we're-all-dead'ly,

That would be nice :-)

Note that MoinMoin already has a feature to download the
complete wiki as XML file. Perhaps you could tweak that
file format into an auto-formatted PDF file.

Fortunately we chose wisely. ;)

sig/moin.cgi/CommonXmlTasks?action=3Dcontent

The decoration you get with some links can be switched off by 
UserPreferences, and I still hope I can get the conversion to XML more 
stable than it is now (still, with some manual tweaking, you can use 
the current conversion to do MOST of the work for you).

When I'm done with the formatter refactoring, I'll come back to you for =

help with reportlab. :)

That feature is not (yet) completed, and also won't buy him anything, 
since pages will be unparsed wiki markup in a CDATA section, at least 
for the moment.

Oh well.

Wouldn't it be possible to recurse through all pages
and use the output of the XML page links to group them together ?

Message-ID: <Pine.LNX.4.44.0206140926020.3031-100000@localhost.localdomain>

Just wanted to ask the Windows users on this list what Python interfaces 
to XSL transformers they are using, and which they think is best.

On Unix, I've used 4xslt, libxslt, and Sablotron.
Of those, I think only 4xslt works on Windows.
I know that the C versions of libxslt and Sablotron are available for 
Windows, but I don't know whether anyone's gotten the Python interfaces to 
them working.
Pyana (the Python interface to Xalan) seems to have been developed 
initially on Windows.
I think I read somewhere that it's possible to interface to MSXML via 
COM, but I don't know if it's possible to do XSLT in that manner.

Anyone have any success stories (or failure stories) they want to share?

This is not a flame, but I'm curious to know
that "...linux has terrible documentation" in comparison to what
operating system ?

Although, I did not swapped Perl for Python because of that ;o)

I think Python "suffers" from such abundance of choices too.
Therefore, I second the need of a comparative documentation, but
I blame no one, except perhaps me for not doing it myself.

Hi Sam

Get the package here:
http://www.zope.org/Members/philh/nXMLDocument

Phil Harris is running a site with Zope and he creates html out of xml
via xslt. Although this is special package for Zope: it is programmed in
python and you do not need the specialities for Web-publishing an
object, which would be specific to Zope. The XSLT transformation itself
is pure Python, done with MSXML on Windows. So if you look at the code,
it will give you a hint maybe.

hello

I just wanted to install pyxml 0.7.1 in my machine (red hat 7.3, python 2.2.1)
with this options

python setup.py build --without-xslt --without-xpath

because I want to use xpath and xslt from 4suite cvs

but xpath and xslt is installed despite the --without-* option.

it only works when I changed the lines 34-35 to

with_xpath = 0
with_xslt = 0

I think this might confuse peope completely new to PyXML

Subject: [XML-SIG] Issue in XMLGenerator and proposed fix
Message-ID: <3D0A2F36.8000100@dyomedea.com>

Hi,

XMLGenerator can be confused by unsual (but not illegal IMO) sequences 
of prefix mapping. For instance:

#!/usr/bin/python
from xml.sax.saxutils import XMLGenerator
from xml.sax.xmlreader import AttributesNSImpl

ch = XMLGenerator()
ch.startDocument()
ch.startPrefixMapping("foo", "bar")
ch.endPrefixMapping("foo")
ch.startPrefixMapping("foo", "baz")
ch.startElementNS((None, "foo"), "foo", AttributesNSImpl({},{}))
ch.endElementNS((None, "foo"), "foo")
ch.endDocument()

produces:

<?xml version="1.0" encoding="iso-8859-1"?>
<foo xxmlns:foo="bar" mlns:foo="baz"></foo>

To fix this, one should remove the prefix from the _undeclared_ns_maps 
list when needed:

     def endPrefixMapping(self, prefix):
         self._current_context = self._ns_contexts[-1]
         del self._ns_contexts[-1]
         # start of proposed modification
	i = 0
	for p, u in self._undeclared_ns_maps:
	   if p==prefix:
	      del self._undeclared_ns_maps[i]
	      break
	   i+=1

I can't reproduce this problem. Are you sure you have been installing
0.7.1? This was a problem of 0.7 that was fixed in 0.7.1. Lines 52 and
55 implement those options.

Lars Marius Garshol's new book, Definitive XML Application Development, just
appeared at my local bookstore. I picked up a copy yesterday but have only
been able to glance at it. FYI, it has three chapters devoted to XSLT (190
pp.). The book looks very comprehensive and seems to take pains to describe
not only how to do XML processing in Python but also why you might choose
one technique over another. I'm not sure why Lars hasn't plugged the book
yet. ;-)

I have a pat excuse for not writing such a document: I'm biased because I 
wrote some of the software I'd be comparing  ;-)

Just kidding.  I've made a bit of a start on this in my little doc project.  
Here's the relevant page:

http://uche.ogbuji.net/tech/python/pyxml/?xslt=pyxml-guide.xslt&item=http://uch
e.ogbuji.net/tech/python/pyxml/pyxml-guide/choosing-software

I'll have to work on trimming those URIs.  Current approach is admittedly a 
quick hack.

I also use Linux, but while some applications and tools have excellent
documentation, there are many areas which are not adequately covered at all. For
example, I want to buy a USB-based CD burner, but it isn't exactly obvious where
to find reliable/definitive information on which devices are compatible, or even
which kernels are most appropriate - can I stick with a 2.2 series kernel, or do
I have to upgrade to a 2.4 series kernel? Moreover, the recommended FAQ and "how
to" documents are either dated, don't provide the required information (usually
because it's a large job to do so), or are deficient in both respects.

Thankfully, some people provide services to fill the holes in the "official"
documentation. I appreciate this because it takes initiative and a lot of effort
on the part of those people, and I suppose it's only appropriate to reciprocate
by offering one's own documentation on subjects that one is familiar with.

I usually write documentation so that I can remember how I achieved things in
the programs that I have written. Sometimes this only occurs after I first have
had to work out how simple things could be done with the technologies concerned.
If we can remove the seemingly unnecessary investigation process at the most
elementary levels (such as: how does one create documents with the DOM API in an
implementation-independent way?), Python will become a much more acceptable
mainstream choice for XML processing in the future.

Subject: [XML-SIG] Ann: XML Regular Fragmentation implementation
Message-ID: <3D0DFE6F.1060104@dyomedea.com>

Hi,

Regular Fragmentations are a simple vocabulary to fragment XML nodes 
using regular expressions that has been proposed with a Java reference 
implementation last year by Simon St.Laurent:

http://www.simonstl.com/projects/fragment/

I am happy to announce a Python implementation with some enhancements 
and an online demonstration if you want to play with it without 
installing the module:

http://downloads.dyomedea.com/python/regfrag/

The extensions brought upon Simon's original proposal are currently been 
discussed on xml-dev:

http://aspn.activestate.com/ASPN/Mail/Message/xml-dev/1245810

Enjoy and thanks for your feedback,

Eric

PS: Don't look too closely at the code, I still feel like a Python 
newbie and have done a very minimal amount of refactoring after my last 
additions.
PPS: I have been told that the usage in the Python community was to keep 
documentation to its strict minimum and haven't wanted to break the rule :-)

The python.org mailing lists use spamassassin, so you can
add a local filter that looks for X-Spam-Level with three or
more asterisks, and moves that to a "probably spam" folder.

Or better, the xml-sig administrator could add a similar rule
to mailman.

(I recommend setting up a local spamassassin filter as well;
shouldn't take you many minutes.  start here:=20

xml-sig is already using the spamassassin stuff.  I asked Greg Ward 
about it, and he said that some internal DNS issues are holding up 
checking against the RBL lists, which explains the recent leakage. 
Until then, the filter is tightened so more stuff will need manual 
approval (by me).

Subject: [XML-SIG] Proper way of generating a parentless Node object
Message-ID: <20020618133247.P5191@galadriel.alyra.org>

Okay, this is a kind of odd situation, but I need to know the correct way to create a Node (Text node or Element, I actually have to create both) that is not attached to a particular document and that can be inserted into any given document.

The situation is this.  I am using a namespace in a document so that I can embed cross-references in the document.  I want to be able to use the same cross-references in several document types.  With this in mind, I've also created a Python class that can read those cross-references and then export them again in several different formats, including XHtml.

The problem, though, is that this cross-reference class does not know what the parent document will be.

Normally, when I need to create a node, I use code that looks like this:

from xml.dom import DOMImplementation

def toHtml (self):
	dom = DOMImplementation.DOMImplementation()
	doc = dom.createDocument(None, u'Target', None)
	target = doc.createElement(u'a')

If I do this, though, I can't attach "target" to anything other than the document named "Target".  So, I was thinking of doing this:

from xml.dom import Node

def toHtml (self):
	target = Node()
	target.nodeName = u'a'
	target.nodeType = Node.ELEMENT_NODE
	return target

But that has me accessing not only internal object variables, it has me *setting* variables that the DOM spec says are supposed to be read-only.

How should I really be doing this?  Essentially, I'm trying to make an element that I can attach to any document.

That is not possible. You need atleast to guarantee that the node is
inserted into a Document originating from the same DOMImplementation.

Furthermore, your instances are of the wrong class: "good" nodes are
instances of subclasses of Node.

> How should I really be doing this?

I believe what you want to do is not possible with standard DOM
API. So you need to revert to implementation-specific extensions. For
4DOM, you can use _4dom_setOwnerElement.

Martin

importNode will work as well.


nodeToAdd = document.importNode(nodeTobeImported,deep=1)
document.appendChild(nodeToAdd)

A ha.  You have come up against one of the things that makes DOM such a pain.  
I'm not sure what the whole fanatical dopcument ownership pattern came from.  
Whether it was limitations on Java (but JDOM doesn't have this limitation, 
IIRC) or some obscure use case the WG was trying to address, but it is an 
eternal pain.

I think all Python  DOM implementations except for 4DOM and cDomlette allow 
you to set the ownerDocument, and I encourage you to just do so directly.  
However, I think it's unsafe for you to use the abstract node interface.  Why 
not just stick to minidom Node objects?

As a more general note: is it time to shrug off this handicap and extend 
Python DOM implementations to allow setting ownerDocument?

One downside is that there are some implementation tricks based on the tight 
relationship with ownerDocument, but I think all of these can be solved in 
other ways.

We would also wan to set proper reference and lifecycle management guidelines 
for nodes.

Subject: [XML-SIG] Deep copy of an element from one document to another
Message-ID: <6r1yb46zs2.fsf@franz.stat.wisc.edu>

Using Python 2.1 or 2.2 and the recently build Debian python2.2-xml
(0.7.1-1) package, I get weird behaviour when I try to copy an element
from one document into another.  The test script is

#!/usr/bin/env python2.2 
import xml.dom
from xml.xpath import Evaluate
from xml.dom.ext.reader import PyExpat
from xml.dom.ext import PrettyPrint
import os.path, re

dom = PyExpat.Reader().fromUri('/tmp/foo.xml')
od = xml.dom.DOMImplementation.implementation.createDocument(xml.dom.EMPTY_NAMESPACE, 'CISrecords', None)
dc = Evaluate('ListRecords/record/metadata/dc', dom).pop()
desc = Evaluate('description', dc).pop()
nd = od.importNode(desc, 1)
print nd.childNodes
rec = od.documentElement
for n in nd.childNodes: rec.appendChild(n)
print rec.childNodes
print nd.childNodes


Basically I am doing a deep copy of the description node as nd then
appending the children of nd to the rec node.  The output shows that
nd consists of both Text Nodes and Element Nodes but only the Text Nodes
are being appended to rec.

Should I expect this to happen?  I don't see anything in the
documentation that would indicate that appendNode would not append an
Element Node.

Is there a better way of doing this?

Right here, you are destroying the list as you walk over it so you end
up skipping items.

1.  Start loop with what is at index 0
2.  Remove the firs thing from the list (with the append child)
3.  Start loop with index of 1 (in the original list this will be the
third item)
etc.

try this
for n in nd.childNodes[:]: rec.appendChild(n)

Another idiom that I like is this:

    n = nd.firstChild
    while n is not None:
        next = n.nextSibling
        rec.appendChild(n)
        n = next

This has the advantage of not creating a separate list.  It is,
unfortunately, more verbose.

Perhaps Python DOMs should implement the iterator protocol:

def _childiter(node):
    n = node.firstChild
    while n is not None:
        next = n.nextSibling
        yeild n
        n = next

class Node:
    ...
    def __iter__(self):
        return _childiter(self)

Message-ID: <6rn0ts5ikj.fsf@franz.stat.wisc.edu>

Thanks again for the replies to my earlier question about a deep copy
of an element into another document.

I have another complication with this operation.  The element that I
am copying has an xmlns attribute defined and this is propagated when I
copy the children.  In the new document I end up with

<i xmlns='http://purl.org/dc/elements/1.1/'>S</i>

and I want only

<i>S</i>

I'm not sure of the terminology but I think this is a result of the original
document defining a default namespace in the enclosing element.  I am
copying the description element from a "Dublin Core" element like

<dc xmlns="http://purl.org/dc/elements/1.1/" xsi:schemaLocation="http://purl.org/dc/elements/1.1/ http://www.openarchives.org/OAI/1.1/dc.xsd" >

   <description>Scherk's graph is a subgraph of the three-dimensional lattice. It was shown by Markvorsen, McGuinness and Thomassen (1992) that Scherk's graph is transient. Consider the Bernoulli bond percolation in Scherk's graph. We prove that the infinite cluster is transient for <i>p</i> &gt; &#194;&#189; and is recurrent for <i>p</i> &lt; &#194;&#189;. This implies the well-known result of Grimmett, Kesten and Zhang (1993) on the transience of the infinite cluster of the Bernoulli bond percolation in the three-dimensional lattice for <i>p</i> &gt; &#194;&#189;. On the other hand, Scherk's graph exhibits a new dichotomy in the supercritical region.</description>

I like this idea, except iterators are 2.2 only.  I suppose the __iter__ 
function would be harmless in an older version, but it puts the onus on the 
user to write his code portably, probably restoring the verbosity the iterator 
would have minimized.

Pretty much inevitable.  The element you copied has a namespaceURI property 
set to xmlns='http://purl.org/dc/elements/1.1/ and a prefix set to None.  This 
causes the re-serialization you're seeing.

I'm not sure what you're greater aim is, but it sounds as if you want to 
change these properties to eliminate the namespace.  I think in many places 
this is an ugly approach.  Perhaps you just want to create a new element on 
the new document which happens to have the same localname as the one in the 
original document, but none of its other properties.

Regarding the iterator:  it's worse than that, though:  I used the
"yield" keyword, which will cause a SyntaxError in Python 2.1.x and
earlier.  That might be a problem for some people, and is more tedious
to work around.  ;-(

Yes.  At least iterators don't introduce new syntax.  I ran into the
generator problem a few weeks back when I tried to introduce more
efficient DOM iterator code.  No way to make a condition around a new
keyword.  I even tried fiddling with distutils so that it would install
one file if Python 2.2 was installed, and another for older versions,
but this was too much of a terror.  Before I gave up, I considered a
hack that would probably work, but was too ugly for contemplation:

exec("yield")

I decided against this  :-)

Sorry that I didn't explain things well.

I am extracting information the dc elements in the source XML document
and creating or adding to another XML document.  The description
element within the dc element contains the abstract of the paper,
sometimes with markup such as <i>, <b>, <sup>, <sub> elements.  The dc
element contains xmlns='http://purl.org/dc/elements/1.1/'.  This is
where my understanding gets vague.  It looks like an attribute but I
believe it is in fact a default namespace.

Anyway, when I copy the description element into another document and
PrettyPrint the target document, I end up with all the markup that
appears in the source document as
 <i>S</i>
showing up in the target document as
 <i xmlns='http://purl.org/dc/elements/1.1/'>S</i>

I want the abstract in the target document to appear like the abstract
in the source document.

Does this help?

so did Guido:

...
>>> bar()
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "<stdin>", line 2, in bar

(the compiler looks for a yield keyword when compiling the

an ordinary function)

Ah.  Makes perfect sense.  SO I guess I'm glad I didn't venture down
that road.

Does anyone have any tricks they've used for dealing with syntax skew
like this?

Okay, this appears to work, so I will go with it for now.

How do people normally process a document for a particular namespace?  Do they have one class or a set of classes that process that namespace only?  I've set my system up so that one class processes a namespace (ns1), and when it encounters a tag for another namespace (ns2), and the schema for ns1 says that's a legal tag, then it calls into the object designed to handle ns2.

Does this make sense, or am I missing an important point somewhere?

I think you have already gotten all the pieces of this.  The elements you
want to copy in the target document are in the dc namespace.  When you copy
them, the processor has to keep the namespace (since the elements are in it
already), thus the declaration that you started out asking about.

The solution has been suggested to: instead of just copying the nodes,
create new ones in no namespace, then copy the attributes and PCDATA that
you want.

Alternatively, you could do it with an xslt stylesheet.   You could pull out
what you want and output it without a namespace prefix.  You could do that
with Python, for example by using 4slt.

Cheers,

Tom P

Hmm.  Color me slow  :-)

I see nothing in Lib/email/Iterators.py itself.  And just in case, I
tried loading it with python 1.5 and got the expected blow-up.

So I assume you mean something more devious than code.

Barry got his utility functions packaged with Python so that he could
just ship portable code, which would try to import these souped-up
functions, and fall back to pre-iterator forms if not available?

If so, Barry gets my Daily Machination Award  ;-)

Fred's probably talking about Iterators.py in cvs, which is
essentially just this:

-------------------- snip snip --------------------
try:
    from email._compat22 import body_line_iterator, typed_subpart_iterator
except SyntaxError:
    # Python 2.1 doesn't have generators
    from email._compat21 import body_line_iterator, typed_subpart_iterator
-------------------- snip snip --------------------

Note that email._compat22.body_line_iterator has a yield statement in
it, make it a Python 2.2-only generator.

I only support Python 2.1 and beyond, so it will definitely raise an
exception with Python 1.5, but I think the concept would hold.
Whether this is a good idea or not is another story, but I wanted the
email package to be both part of the Python distro, and a separate
distutils package compatible with Python 2.1.

    UO> If so, Barry gets my Daily Machination Award ;-)

Hehe, yeah, that's all there is to it.

email._compat22 uses Python 2.2.x-only syntax; if importing that
fails, it falls back to the Python 2.1.x-compatible version in
email._compat21.

He doesn't support Python 1.5.2 in the email package, but doing so if
similar to this; just write a group of modules that each require some
feature specific to the oldest version of Python they support, and use
a "master" module (email.Iterators in this example) that imports each
and catches the exception from each that indicates the running Python
is too old to support the implementation.  For the oldest supported
version, just don't catch any exceptions.

The magic is all in using the right checks and exceptions types.
Others call it the brute force approach.  ;-)

Hi,

xvif (attached announce) is both more and less than a Relax NG processor
written in Python.

Less since it's not (yet) supporting all the features of Relax NG (but
the features which are implemented are fully implemented and pass the
213 tests of the official Relax NG tests suite corresponding to the
subset of implemented features).

To make it short, everything is implemented except any other datatype
system than the built-in one and except the reference to external
grammars.

It's also more since it's a proof of concept for an interoperability
framework allowing to define transformations to the nodes being
validated (you'll find more info in the attach annoucement).

Finally, I'd like to thank all the people who have helped me getting
started with Python / XML, and especially Uche Ogbuji who has been more
than helpfull!

Enjoy,

Eric

Hi,

I am happy to announce a first version of Xml Validation
Interoperability Framework (xvif), a proposal for embedding pipes of
transformations and validations within grammar based schema languages.

While the common approach is to define pipes of transformations and
validations operating on complete XML documents, my purpose with xvif is
to explore the possibility of defining "micro-pipes" transforming
information items (ie attributes, text and element nodes) during the
transformation itself.

The main advantage in doing so is to bring the transformation closer to
the place where it is needed. This makes it more easy to maintain, but
also allows it to interoperate more closely with the schema language:
with Relax NG and xvif I can say for instance that an element is valid
if it gives a result 1 matching a pattern1 after a transformation 1 *or*
if it gives a result 2 matching a pattern2 after a transformation 2.

In this proposal, I have given the main focus to defining the
interoperability framework itself, relying on existing technologies for
the transformations and validations defined in my micro-pipes (XPath,
XSLT, Regular Fragmentations and regular expressions are supported in
the current implementation).

Some of these pipes are rapidly getting quite complex which IMO
shouldn't be seen as a problem of the framework itself but rather as an
indication that it might be needed to define a lightweight
transformation language specific to such applications.

This prototype is based on a partial implementation of Relax NG written
in Python (I have focussed on the features which I have found most
important for my proof of concept) using the derivative algorithm
described by James Clark.

The following resources are available in this first version:

- Strawman: http://downloads.xmlschemata.org/python/xvif/xvif.html
- On line demo: http://downloads.xmlschemata.org/python/xvif/tryMe.cgi
- Download: http://downloads.xmlschemata.org/python/xvif/

I assume that discussion about xvif can be carried on xml-dev, but I
have also setup a more specific mailing list for XML schema related
discussions at xmlschemata@xmlschemata.org:

- http://lists.xmlschemata.org/xmlschemata/

Enjoy!

Eric

Lars,

Thanks for the expression of interest.

Now the real question is, who would be interested in working on such a
project?
I've been doing open source for too long to be interested in doing another
project solo.
Projects I'm currently managing are Quick, JXUnit, JXWeb and QARE----and
QARE is more than a full time job.

On the other hand, Quick is old enough that it is time for a radical
overhaul. Switching
to Python would do that.

Quick has been through 3 name changes and 7 complete rewrites. Quick uses a
tree factory
pattern. Its predicessor, MDSAX, used a SAX filter patern. Before that was
Coins, which was
rather ad hoc.

What I'm proposing for PyQ would use the Model/Control and
Model/View/Control
patterns. Which should be a lot easier to work with than tree factory. All
of the Quick
utilities currently build on M/C and M/V/C. See the section on Transforming
XML in
the Quick Guide at
http://www.jxml.com/2001-12/products/quick/guide/index.html#transform

I have found that M/C and M/V/C are powerful patterns for transforming XML
and data.
The Quick utilities transform XML into XML, Java Model Classes, Java
[Un]Marshaling
Classes and DTDs. And while Quick provided reasonable support for binding
XML to
pre-existing Java classes, I believe PyQ would provide even greater
flexibility.

For more information on Quick, you might want to take a look at the O'Reilly
book, Java &
XML Data Binding by Brett McLaughlin. Chapter 9 and appendix B are devoted
to Quick.

Bill

Summary: Entity names in sgmlop

Initial Comment:
sgmlop handles entity names incorrectly in XML mode. 

According to
http://www.w3.org/TR/2000/REC-xml-20001006#sec-references
(Rule [68]):

EntityRef    ::=    '&' Name ';'

and

http://www.w3.org/TR/2000/REC-xml-20001006#NT-Name
(Rules [4], [5]):

Name ::= (Letter | '_' | ':') (NameChar)*
NameChar ::= Letter | Digit | '.' | '-' | '_' | ':' |
CombiningChar | Extender 

So "-", "_" and ":" are allowed in entity names.

sgmlop currently uses (ISALNUM(*p) || *p == '.')
to test for legal characters inside entity names for
both modes (SGML and XML).

This patch adds "-", "_" and ":" to the set of allowed
characters (but only for XML mode).

Subject: [XML-SIG] PyXML-0.7.1 expat ext. build failed under sygwin
Message-ID: <F15yDE8IqpFuiHV5EIK00013e2e@hotmail.com>

Hello,

---------------------------------------------------------------
Target:
I need the XML SAX parser for Python under Cygwin.

Description of the problem:

After unpacking of the tarball, the issuing the python setup.py build
cause the following compiling error during building the expat extention:

---------------------------------------------------------------
Workaround:

the simple code review and primitive test like:
void funcA(int a, int b)
{
  printf("from A: %d, %d\n", a, b);
}

void funcB(int a, int b)
{
  printf("from B: %d, %d\n", a, b);
}

typedef void (*PF)(int, int);

struct S {
  const char * _F;
  PF           _pf;
};


extern struct S ars[2];

static struct S ars[] =
  {
    {"funcA", funcA },
    {"funcB", funcB },
  };

int main()
{
  printf("%s ", ars[0]._F);
  ars[0]._pf(1, 2);
  printf("%s ", ars[1]._F);
  ars[1]._pf(3, 4);

  return 0;
}

and
$ gcc -o test main.c

shows that everything should be all right. But it is not...

---------------------------------------------------------------
Searching the net:
1. I did not find the precompiled version of the PyXML for cygwin.
   Could you build and put on the site the precomiled version for the cygwin 
as well? I believe that cygwin's rpm would be more then enough.
2. The problem like "initializer element is not constant" is shown but the 
recommendations goes to the updating of the gcc compiler with unclear 
direction. That's possibly true, but instalation of the GNU's projects under 
cygwin is a different story.

With the best regards,

I have something similar. It can currently  generate Python classes and 
C code for expat.

The Python classes are probably quite straight forward:
- each <!ELEMENT  ...> gets it's own class
- attributes become instance variables, initialized to the default value
- def set_attributename () is generated for each attribute
- sub elements become also instance variables, initialized to None
- def add_subelementname () is generated
- list elements <!ELEMENT List (ListItem*)> are generated as subclasses 
of UserList
- customization is done by subclassing these classes and using a factory 
with these subclasses during the parse

The C/expat version generates a parser which calls setter methods on 
independently defined classes, which seems also the way Quick works 
(after one very quick look into the XML Binding book)

I'm going to put the code, docs and some examples on the web so that you 
can see if it would be along your line.

By the way, I named it FOM for Fixed Object Model (this would make DOM 
the Dynamic Object Model).

Message-ID: <200206210515.AAA21224@isua5.iastate.edu>

Hello,

I have difficulty installing the PyXML-0.7.1 software.  Though it may 
very well be due to my incompetence, the README said to write you.  When 
I type in 

python setup.py build

I get a 

Traceback (innermost last):
  File "setup.py", line 9, in ?
    from distutil.core import setup, Extension
ImportError: No module named distutils.core

Can you help?  I'd greatly appreciate it!

Cheers,

Mark

The usual reason for this error is that you don't have the Distutils
package installed. And the usual reason for *that* is that you have an
old version of Python, say, 1.5.2.

If that's the case, you can either download the Distutils from

    http://www.python.org/sigs/distutils-sig/download.html

or upgrade to Python 2.2, which includes the Distutils by default.

For the most part Python 2.x is backwards compatible with 1.5, so unless
you are running a Linux distribution that makes heavy use of
Python-1.5.2-based utilities (mainly RedHat, I think), you should
probably just upgrade. 

Another option is to install 2.2 alongside the older version. There was
a thread on that topic about a week ago ... shouldn't be too hard to
find in the archives.

The other very usual reason is the broken Debian packaging which puts di=
stutils 
into a *-dev* package.

I'm not sure. I accepted three or four patches into PyXML that all
said that they make pyexpat compilable for Cygwin, I release the
package, then somebody tells me that it won't compile. I don't know
what to think.

It might be nice for one of the Cygwin users to take the Expat sources
from the 1.95.3 Expat release and see if they improve things.  I think
most of the Cygwin-driven changes in this Expat release were in the
build process and not the library sources, though.

Subject: [XML-SIG] Updated xmlchargen for Namespaces productions
Message-ID: <1024669806.27476.163.camel@ibook>

Hi,

I have forgoten to mention it before, but I needed regexp for XML
Namespaces productions such as "NCName" and I have updated a version of
pyxml's xmlchargen.py.

This is available at:
http://downloads.xmlschemata.org/python/xvif/xmlchargen.py

Many thanks for this utility which saved me plenty of time!

I was wondering if other such regexp utilities are available. For
instance to implement W3C XML Schema patterns we would need regexps for
the unicode blocks and categories. Is this available somewhere?

Thanks

Eric

You grabbed the source file for PyXML and do not have a compiler (i.e. 
Visual C++) installed on your computer.

You can download the pre-compiled version from this link:

http://prdownloads.sourceforge.net/pyxml/PyXML-0.7.1.win32-py2.2.exe?download

Just download the file, run it, and it will be installed.

I've kicked up a few useful routines today for DOM processing with
Python 2.2.  (BTW, generators kick ass).

I've attched a module of these routines just in case they come in handy
to others.  I must say that the combo of generators/iterators and list
comps makes this code extraordinarily cleaner and faster than it would
have been in, say Python 1.5.

BTW, if someone more graphically inclined than I wants to write the
stubbed out function dom_trace and post it back here, I'd be happy to go
into debt of a beer.  What would really be cool is a routine that emits
an SVG diagram of a DOM's contents.  Based on stuff I've seen done with
SVG, this should be quite feasible.

As promised, it's updated with eight new items.  Plenty of new code examples 
and pointers.

Thanks for pointing this out.  I now cover all these items, including updates 
and commentary where appropriate.

Summary: minidom problem in 0.7.1 with python2.2

Initial Comment:
Putting on my Debian Maintainer cap...

I've received the following bug report:

From: Jenya <me@oblom.com>
To: alf@logilab.fr
Date: Mon, 17 Jun 2002 20:17:14 +0300
Subject: python2.2-xml breakage ?


Hello.
I updated today python2.2-xml to latest and greatest
(0.7.1-1) and bunch of
other things that i didn't noticed (you know, apt-get
upgrade thingie), and
after executing :

import xml.dom.minidom
doc =  xml.dom.minidom.parse("somefile.xml")

expirienced following error :
  File
"/usr/lib/python2.2/site-packages/_xmlplus/dom/minidom.py",
line 962,
in parse
    return _doparse(pulldom.parse, args, kwargs)
  File
"/usr/lib/python2.2/site-packages/_xmlplus/dom/minidom.py",
line 954,
in _doparse
    toktype, rootNode = events.getEvent()

line
194, in feed
    self.reset()
  File

line
232, in reset
    self._parser = expat.ParserCreate(None, " ", intern
= self._interning)
TypeError: 'intern' is an invalid keyword argument for
this function


By replacing line 232 in expatreader.py from
self._parser = expat.ParserCreate(None, " ", intern =
self._interning)
to
 self._parser = expat.ParserCreate(None, " ")
problem got fixed, but i am not sure how right this
solution is.
those days expat.ParserCreate accepts only 2 parameters :

ParserCreate([encoding[, namespace_separator]]) -> parser
Return a new XML parser object.

        Evgeny

Summary: adr_parse skips entries and breaks tree 

Initial Comment:
Please see

for a full description of the bug. 

---------------------------------


I was having a hard time converting an Opera 6 bookmark
file for use
with galeon until I discovered what I consider a bug in
adr_parse.

The output of adr_parse was missing the first bookmark
entry of all
folders and also seem to have hooked the bottem part of
my top-level
bookmarks deeper into the tree structure. As I
understand from the
adr_parse source, the fields "VISITED" and "ORDER" are
optional.
Unfortunately, the "skip of optional fiels"-logic in
the script does not
work [Once a line is read and recognized as not holding
the expected
field, it
is essentially DISCARDED. It is not compared to the
next possible
optional field name. This results in reading to many
line for a single record
and missing the next one completely (w/ "swallow_rest").]

Since this problem only occures for fields that are not
used later on in
the script (ie. parsed needlessly), I just removed the
parsing entirely
and leave the skipping to swallow_rest. I can report
complete success
with that.

This solution also (like the original code intended for
optional fields)
does not solve the problem of parsing optional fields,
but it
at least allows me to parse the file properly for the
given purpose.

for a full description of this bug.

------------------------------------

When converting my Opera 6 bookmarks to xbel I found
what could be
considered a bug in adr_parse. Bookmarks containing
non-ASCII characters
(in my case Umlauts äöüß) are represented in utf8 in
the opera6.adr file
according to its header:

Opera Hotlist version 2.0
Options: encoding = utf8, version=3


Using the output of adr_parse (utf8 code was copied
unchanged by adr_parse)
as bookmarks in galeon reveals the problem: Bookmark
entries are
truncated at the first non-ASCII character.

A manual fix of the bookmarks.xbel seems to have solved
the problem:
- -<?xml version="1.0"?>
+<?xml version="1.0" encoding="UTF-8"?>


This may not be a bug in adr_parse, but in bookmark.py,
as it seems to
do UTF-8 encoding without declaring it.

Hi,

I had problems with msie_parse. It gives me only hierarchy, no links.. 
Like this ( following is a fragment of my .xbel file generated by 
msie_parse program)
.
.
.
  <folder>
    <title>games</title>

  </folder>
  </folder>
.
.
.

Please guide me what should i do? what could have been wrong? The 
interested part is, all links automatically coming with IE, like MSN etc 
worked fine. But all links (favorites) created by me in IE did not come 
truly. I was using IE6, now i have shifted to Debian GNU/Linux and using 
Galeon as my browser.

Hope to here from u soon..

Thanks,

1. X-Hive Corporation Launches Version 3.0 of Its Native XML Database

X-Hive Corporation announced the release of version 3.0 of X-Hive/DB, the
native XML database designed for software developers who need to process and
store XML data in their applications. X-Hive/DB supports all major XML
standards including XML 1.0, XQuery, XPath, XPointer, XLink, XSL, XUpdate
and DOM. It also offers a transaction mechanism, versioning with branching,
BLOB storage and various indexing methods, as well as support for J2EE and
WebDAV.

Next to overall performance improvements the following features have been
added or enhanced in X-Hive/DB 3.0:

- Support for XQuery
- Support for DOM Level 3 Abstract Schema
- Support for DOM Level 3 Load & Save
- New indexing method: element name indexes
- Improved XPath/XPointer API
- Improved administrator client
- Simplified database setup

X-Hive/DB 3.0 is available on Linux, Solaris and Windows. A free 30-day
evaluation license can be obtained from www.x-hive.com.
More information see http://xml.startkabel.nl/ section "what's new".

2. IBM developerWorks papers:

1)Counting with node sets
Many common XSLT tasks, including simple loops, can be made easier by using
special properties of node set operations. This tip discusses using node
sets for simple and efficient loop control. (contains sample code)
More information see http://xml.startkabel.nl/ section "what's new".

2) XML for Data: XSL style sheets
This article examines the two most common authoring styles used to create
XSL style sheets: push and pull. It takes a look at some simple XML and XSL
examples and discusses the benefits and drawbacks of each approach.
(contains sample code)
More information see http://xml.startkabel.nl/ section "what's new".

3) Outputting HTML from an XSL style sheet **
Because HTML is so similar to XML, it should be fairly straightforward to
create an XSLT style sheet that outputs HTML. Unfortunately,
the differences between HTML and XML that do exist can cause pages to be
displayed incorrectly in older browsers. This tip discusses those
differences, and explains how to use XSLT's output element to resolve the
issues they create. (contains sample code)
More information see http://xml.startkabel.nl/ section "what's new".

4) Leverage the extensible DITA DTD
In current approaches, DTDs are static. As a result, DTD designers try to
cover every contingency and, when this effort fails, users have to force
their information to fit existing types. The Darwin Information Typing
Architecture (DITA) changes this situation by giving information architects
and developers the power to extend a base DTD to cover their domains. This
article shows you how to leverage the extensible DITA DTD to describe new
domains of information. (contains sample code)
More information see http://xml.startkabel.nl/ section "what's new".

5) Choose the style sheet based on the XML document
Using Extensible Stylesheet Language Transformations (XSLT) is often the
easiest way to transform your XML data from one form into another, as it
allows you a great deal of flexibility without having to change an
application. On occasion, however, you may run into a snag because the style
sheet to be used is based on the content of the document itself. This
article discusses two ways to base your choice of style sheet on the XML
document -- the style sheet processing instruction and the data itself.
More information see http://xml.startkabel.nl/ section "what's new".

6) An introduction to Web Services Gateway
Web services can be accessed from applications and processes both within the
corporate firewall and beyond it. Fundamental to this is how the service,
deep inside your enterprise network, is exposed to external users. This
article looks at the issues involved in this approach and how IBM's Web
Services Gateway addresses these issues. (contains sample code)

knowledge. XML is a superb tool for increasing the return on information.

If you can look through archives of the list, you will find a post from me
several months ago with some patches to the XBEL code for Internet Explorer
bookmarks.  If you can't find it, write again and I'll try to find it.  I
just had my computer die and can't get at it right now.

There might be a bug in msie_parse, or in Internet Explorer (in the
sense that it changed its bookmark format after msie_parse was
written).

So if you you could try to find Tom's patches, and/or you could debug
the program yourself, and fix any remaining problems.

Alternatively, you can make a bug report at sf.net/projects/pyxml;
please include the bookmark file that you wanted to convert in this
case.

Martin

Summary: Problem with msie_parse program

Initial Comment:
Hi Folks,

I have some problem with msie_parse program. I was
using Windows as my primary os few months ago, now i
have transfered to Debian GNU/Linux and its realy fun
to use such a powerful os. I use Galeon browser now,
which keeps bookmarks in XBEL format. I want to convert
my Favorites i created using IE6 to xbel format which
Galeon can interprete. 

I tried using msie_parse program, but it is not
generating xbel properly. It generates only folder
entry like...
.
.
.
  <folder>
    <title>games</title>
  <folder>
    <title>chess</title>
  </folder>
  <folder>
    <title>cricket</title>
  </folder>
  <folder>
    <title>formula1</title>
  </folder>
  </folder>
.
.
.
I don't know python, other wise i would have tried to
debug this. Is the problem because i used IE6 ?? I am
attaching the favorite folder gipped with this mail.
Please take it and test it.

Thanks,

Dharmesh

It is both.  IE changed (probably extended with new features) its bookmark
format, and there is a bug that prevents directories from being correctly
nested in the output xml.

After I fixed the code, I was able to turn my collection of IE favorites
into nearly 1000 bookmarks into XBEL format, and from there using a
stylesheet I created an XTM topic map from them.

Cheers,

Tom P

In that case, I'd appreciate if you or somebody else digs up your

In-Reply-To: <3D1969BE.2040901@yahoo.com>
Message-ID: <Pine.LNX.4.44.0206261308150.4374-100000@localhost.localdomain>

I just released a new version of maki.

http://maki.sourceforge.net

maki is a webserving framework built on Python and XML. It allows a web 
developer to send an XML input document through any number of steps, where 
each step is either a stylesheet transformation or a custom process. A 
processor that evaluates embedded Python code is included. The output of 
each step is passed as the input to the next step (similar to a Unix 
pipe). Additionally, the output of each processor step can be cached for a 
user-specified time period. All configuration is done in XML files that 
allow you to specify rules based on matching paths against Unix-style 
wildcard patterns or regular expressions. 

The biggest change from previous versions is that this version can work 
with mod_python, FastCGI or Webware.  

I've also improved support of libxslt, added support for Pyana, made sure
it works with the latest version of 4xslt, and added some more examples.

I found a backup copy of my changes.  Here is the fixed script - I will see
about the SF tracker another time.  Actually I would appreciate someone else
doing that - I'm supposed to get my replacement computer tomorrow and will
be very busy setting it up and catching up with my writing for quite a
while.

 __walk() and __geturl() both had to change.  __walk() did not close folders
at the right time, so they did not nest correctly.  __geturl() assumed a
particular format for the bookmark file, but on more recent versions of IE,
the format changed.

Cheers,

Since Tom posted an entire file rather than a patch, shall I just check it in?

You mean Tkinter applets?

First of all, an XML-oriented list is really not the best place for a
question like this. If there isn't a Tkinter or GUI SIG, then probably
comp.lang.python would be most appropriate. But since I'm answering
anyway ...

I think the answer is no. The closest thing I have seen to it is the Tcl
Plugin that somebody (Sun?) was distributing 3-4 years ago. If you could
find that, and if it were Open Source (but it's not if I remember
right), you could conceivably hack it to act as a Tkinter back end. But
I don't imagine you want to do that. I'm not aware of any plugin that
will, out of the box, let you deploy a Tkinter applet.

This is probably caused by not compiling the pyexpat that came with
PyXML. Try reinstalling with --with-pyexpat.

It would be good to double-check that you won't undo later changes
that way, but otherwise - please do.

Hi!

What do you people think of adding a module that can handle the "Python =

conversion between that and a SAX stream (in both directions), which 
would the basis for such a module.

Message-ID: <200206301507.g5UF7isO003037@paros.informatik.hu-berlin.de>

Folks,

I've added an encoding argument for toxml and toprettyxml both in the
PyXML and the Python CVSs. Making 'utf-8' the default is unfortunately
not possible for backwards compatibility.

Please let me know what you think about this change, in particular
whether it should be made available in Python 2.2.2 as well.

Regards,
Martin
