Summary: PrettyPrinter uses single quotes

Initial Comment:
The pretty printer emits single quotes areound 
attributes by default.  Unfortunately, single quotes 
aren't supported by all XML parsers - really I'm not 
sure they are part of the XML standard (?!?!?).  In any 
case, I wanted to pretty-print some XML but the result 
was unparsable.  Hopefully the use of single-quotes 
will be removed, or made optional, in the next version.

sure, but the scope of your original post was probably too large for anyone
to deal with...

anyway, if you want an XML parser that gives you full access to the DTD,
this might be your best choice:

    http://www.garshol.priv.no/download/software/xmlproc/

if you meant plain XML and not DTD (I'm not sure how the DTD can contain
command descriptions...), there are dozens of alternatives.  you can find links
to most of them in this article:

    http://www.xml.com/pub/a/2004/10/13/py-xml.html
    (also see the comment section)

Subject: [XML-SIG] XT (XML Toolkit)
Message-ID: <438F0749.4090904@gnucitizen.org>

Guys I've been working in the past few weeks on a project that was
previously called Hackers XML Toolkit. Well, after the official release
I liked it so much that I changed the name to XML Toolkit. You can
download the code from

http://www.gnucitizen.org
http://www.gnucitizen.org/data/download/xt-0.7.BETA.py

Check it out and tell me what you think. BTW, there is a simple demo of
the stuff you can do with XT. My module is not as powerful was SAX or
DOM but has some neat functionalities that may simplify your work a bit.

# DEMO
import xt

element = xt.Element().loadstring('''
<element><name>XT<name/></element>
''')

element = xt.Element().loadfile('xml.xml')

element[0]

for e in element:
    print e.namespace

e['document']
e['{urn:namespace}document'].name = 'the_document'
e['definitions']['service'].attributes['name']

element.sort()
element.append(Element('another_one'))

Well, you can use it in many other ways. :)

Thanks.

Subject: [XML-SIG] automatically building Python data structures from DOM
	trees?
Message-ID: <dmpbve$6vn$1@sea.gmane.org>


Hi,

I'm looking for a package that will translate a minidom tree into 
something which  is native python, i.e. translate

<bar>
    <bla>
       <foo id="1" />
       <foo id="2" />
    </bla>
</bar>

into a python object, for which the following holds

    bar.bla[1].id == "2"


Of course,  I would have to supply a mapping from names like "bar" and 
"bla" to my own classes (probably deriving from xml.node).

Does such a thing exist?

Well, why don't you try my XML Toolkit
http://www.gnucitizen.org/data/download/xt-0.7.BETA.py

This is what to do

import xt
element = xt.Element().loadstring('''<bar>

    <bla>
       <foo id="1" />
       <foo id="2" />
    </bla>
</bar>''')

element = xt.Element().loadfile('myfile.xml')

for e in element:
	print e.name
	print e.namespace

print element

print element['bla'].findall('foo')
print element['bla']['foo'].attributes['id'].namesace
element['bla']['foo'].attributes['id'] = 'This is a new id'

for e in element['bla'].findall('foo'):
	print e.attributes['id'].value


element['bla'].append(Element().loadstring('<foo>Another bla<foo>'))
element['bla'].append(Element('foo'))

Cheers

does it has to be a minidom tree?  if not, you can find plenty of alternatives
under the "data bindings" section in this article:

    http://www.xml.com/pub/a/2004/10/13/py-xml.html

Yes, Try Amara (http://uche.ogbuji.net/tech/4suite/amara/)

<monty>
  <python spam="eggs">What do you mean "bleh"</python>
  <python ministry="abuse">But I was looking for argument</python>
</monty>

Becomes a data structure such that you can write:

binding.monty.python.spam

In order to get the value "eggs" or

binding.monty.python[1]

I wrote something like this except it just parses XML -- it doesn't go
through (mini)DOM. It also *produces* XML from the Python data
structures at request.

It's not yet integrated anywhere but you can get it from SourceForge:
python.org/sf/1337648.

I've been looking for feedback on this package -- let me know if it's
useful for you!

Thanks, Luis.

Yep, and 'bar.bla[1].id == "2"' would work out of the box with Amara.

One question, Han-Wen, do you have to use minidom as the source, or can
you go from straight XML?  Just seems unnecessary to parse to minidom
and then bind.

No, but I'd like to have the source as a complete, in-memory tree. I 
thought that DOM was just a word for such a tree. I'm a complete XML 
newbie.

For the moment, I have concocted something simple with new.classobj() - 
if I need anything more complex, I suppose that I'll have a look  at Amara.

 From the comments, I gather that it doesn't preserve the ordering of 
elements in the XML file. That would make it useless for me.

No, but I'd like to have the source as a complete, in-memory tree. I 
thought that DOM was just a word for such a tree. I'm a complete XML 
newbie.

For the moment, I have concocted something simple with new.classobj() - 
if I need anything more complex, I suppose that I'll have a look  at Amara.

It preserves the relative order of subelements of the *same* type
(which are stored in a list, to match your example), but indeed it
currently doesn't preserve the order of subelements of different
types. I'll note that as a feature request.

Some people use the term that way.  I wouldn't.  There's a W3C standard
called DOM, which is a tree.  It's also very suboptimal for Python.
Minidom is based on DOM but tries to make some concessions to Python's
simpler world view.  Many will tell you it's still way too Java-esque.

There are other tree models for XML that have nothing to do with DOM,
including Amara and ElementTree.

  Hello,

I'm new to SOAP and pyXML. I tried to use the ZSI. Not sure about SOAPpy 
- is it better for me?

Here is my test program:

import ZSI
fname = 'eBaySvc.wsdl'
version = 421
url = 'http://developer.ebay.com/webservices/%s/%s' % (version,fname)
print "Creating proxy..."
proxy = ZSI.ServiceProxy(url)
print proxy

Results in an exception:

    proxy = ZSI.ServiceProxy(url)
  File "C:\Python24\Lib\site-packages\ZSI\ServiceProxy.py", line 34, in

Now I also tried SOAPpy but it throws the same exception in XMLSchema.py 
(which belongs to wstools - the same code base for SOAPpy and ZSI).
This is what the web service provider states on its home page:

"If you choose to also try a different SOAP client, please be sure it 
supports document-style messaging (as we do not use RPC-style 
messaging). Also, the SOAP API only supports the UTF-8 encoding scheme."

Sorry for the dumb question, but what is "document-style messaging"? 
This web service provider tells me that the supported platforms are 
Visual Studio .NET and Apache Axis. I have FreeBSD 4.8 which I must use, 
but AFAIK Java does not run on it. :-(  I would like to use Python.

I have similar things in the WDSL:

    <wsdlsoap:binding style="document" 
transport="http://schemas.xmlsoap.org/soap/http"/>
   <wsdlsoap:body use="literal"/>

So do you think it will work with SOAPpy or ZSI?
The web service provider said "You are free to use other SOAP client 
environments, but the tool you use must support document/literal style 
SOAP messages."
But I'm not sure if ZSI or SOAPpy supports this or not.
Thanks,

   Laszlo

I'm trying to create python source code for a wsdl.
According to the ZSI documentation, there is a 'wsdl2py' program that 
can create python interfaces for a given wsdl.
But there is no such program in the distribution.

http://pywebsvcs.sourceforge.net/zsi.html#SECTION0012300000000000000000

For this reason, I tried to use the WriteServiceModule function:

import ZSI
import ZSI.wsdl2python
from ZSI.wstools import WSDLTools

fname =  'eBaySvc.wsdl'
reader = WSDLTools.WSDLReader()
wsdl = reader.loadFromFile(fname)
print wsdl
wsm = ZSI.wsdl2python.WriteServiceModule(wsdl)
wsm.write()

Result:

C:/Python24/pythonw.exe -u  
"T:/Python/Projects/eBay-SOAP/create_interfaces.py"
<ZSI.wstools.WSDLTools.WSDL instance at 0x00A2A738>

Warning: invalid operation for <any>

It is only a warning but it terminates the operation. What am I doing wrong?
Sorry for the bunch of questions. This is the first time I use SOAP.

Subject: [XML-SIG] <!DOCTYPE type> declaration missing in PrettyPrint()
Message-ID: <43977F61.7040808@abletronics.com>

I've seen something related to this in the archives, and it didn't look 
good.

I'm writing a python script to convert a report to XML to import into 
another program.

The problem is that the import function of the other program requires a 
<!DOCTYPE> declaration:

=== EXMAPLE ===
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE IMPORT>
<IMPORT>
     <some elements />
</IMPORT>
===

I've created a script using:

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

reader=Sax2.Reader()

doc=reader.fromString("""
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE IMPORT>
<IMPORT>
</IMPORT>""")

(create nodes)

ext.PrettyPrint(doc)
====

Unfortunately, it does not output the <!DOCTYPE> line:
=== EXMAPLE ===
<?xml version="1.0" encoding="UTF-8"?>
<IMPORT>
     <some elements />
</IMPORT>
===

Any suggestions?

Subject: [XML-SIG] XMLToolkit 0,7,BETA.2
Message-ID: <43980CD6.9070105@gnucitizen.org>

Hello to everybody,
This is XMLToolkit 0,7,BETA.2. I simplified most of the code. There are
a few new features added as well. Now you can use the Binding tool to
Bind XML documents to python objects.

doc = Binding.fromfile('GoogleService.wsdl')
doc.definitions.message
doc.definitions.message[0]
doc.definitions.message[1]
doc.definitions.message.name
doc.definitions.message.name = 'bla bla'
doc.definitions.message = '<h1>Hei I can assign XML to elements that
will be parsed on the fly.</h1> Good!'
doc.definitions.message[1] = OtherBinding
doc.definitions.message[2] = OtherElement
doc.definitions.message[0] = doc.definitions.message[2]
for m in doc.definitions.message:
    print m
    print m.name

doc.xml
doc.xml(encoding = 'utf-8')
doc.xml(encoding = 'utf-8', stream = mystream)
doc.xml(encoding = 'utf-8', file = 'myGoogle.wsdl')
str(doc.xml)
doc.xml.composestream(stream)

As you can see the syntax is similar  to Amara XMLToolkit.
I am still stuck with PEXComposer. If anyone is willing to help me out
with simplifying the code and writing proper Composer to assemble PEX
Objects back to XML, feel free to let me know. It shouldn't take that long.

I need your help more than ever. I believe that XT (XML Toolkit) is
coming nicely and I want to complete it as soon as possible because I
want to move forward and start doing something else. :) So, can you have
a look on the code and suggest any corrections or recommendations? Or
even help me out rewriting some of it. I believe that the current design
is not bad at all, however, somebody may suggest a different approach to
solve a problem.

Thanks.

P.S. These are the detail of my project:
I have to create a distribuited application to manage a wireless network.
In the manager program there is a GUI in wxPython that has many commands 
to send to the agents.
To send the command to the agent (that is in C++ language) the manager 
use XML in Python string.
The agent uses the commands parsing the string but this is not a problem.

Thanks for the advice. It is a good one.
I am currently finishing up the library.

For all of you who really cant get why I am wasting my time codding 
another XML library.... Well, I am security  guy and I need small 
library that does the main things. I hope you can use XT in a similar 
way. The official 0.7 version will be out soon.

Thanks for the advice again.

this doesn't do what you think it does:

Oh, yes :)
You are right. I guess the best thing to do is:
return cdatastring[9:-3]

Right now I am rearranging all the parsing methods. Also, I am adding 
methods that can compose xml.

Thanks.

Message-ID: <KFEALFFBKIEFLMFHHOEMIEMNCBAA.mcharest@sogetel.net>

Hi,

characters (specifically, french text accents)?

# Create an XML document:
doc  = implementation.createDocument(None, 'cases', None)
root = doc.documentElement
celem = doc.createElement('case')
pelem = doc.createElement('problem')
felem = doc.createElement('feature')
felem.appendChild(doc.createTextNode( "?l?ve" ))                       #
Method1 (see ERROR 1)
#felem.appendChild(doc.createTextNode( unicode("?l?ve", 'latin-1') ))  #
Method2 (see ERROR 2)
felem.setAttribute("fid", "1")
pelem.appendChild(felem)
celem.appendChild(pelem)
root.appendChild(celem)
root.setAttribute("date", "jan 01 2005")

# Print generated XML document:

The xml.dom.ext PrettyPrint can only handle 7-bit ASCII or Unicode 
encoded text node strings.  Method1 will fail as your latin1 encoded 
string contains 8-bit values which are not valid utf-8 encodings, as the 
error message reports.  Method2 is in fact working - the output you see 
is the utf-8 encoding for your text node string.  If you look at the 
output generated in a Unicode editor you should see your original string.

The xml.dom.ext PrettyPrint can only produce utf-8 output.  There is a 
bug report and patch on sourceforge to let it produce utf-16 output.

I decided to split the library to smaller files because it is getting 
bigger than I initially expected. But this is fine because now you can 
use just specific parts of the code for specific purposes in your 
application. The package will include a standalone version of the 
library as well which will be out 1500 lines of code including the 
documentation.

First of all I would like to know if this is a good idea?

Now, I am interested in something very specific and I would like to hear 
your comments. The attached file contains the parsing part of my 
library. So far I like the Parser and ParserNS classes. However, I would 
like to add classes that are opposite to them (these classes should 
contain methods that are opposite to those found in Parser and ParserNS, 
more over they have to be called almost in the same way to reduce 
developers frustration when using the library).

The classes that are opposite to Parser and ParserNS are called Composer 
and ComposerNS. The reason I would like to do this kind of separation is 
because if both Parser and Composer are written in certain way using 
certain conventions, less XML would be lost when converting from xml to 
object and vice versa.

I am kind of stuck with the Composition again. The Composer must be 
almost identical in nature to ParserNS but opposite if you know what I 
mean. This is how the parser works.

Parser.parsestring(string, handler) -> None
            |
            |
            V
Parser.splitstring(string) -> generator
            |
            |
            V
Parser.parsenodes(generator, handler) -> None
            |
            |
            V
handler - events


The Composer should do exactly the opposite of Parsing.

Composer.composestring(....) -> string
            |
            |
            V
handler - events
            |
            |
            V
Composer.composenodes(...., handler) -> generator
            |
            |
            V
....

Maybe I am confused and I am complicating the overall design too much. 
KEEP IT SIMPLE, yes this is my philosophy in live but it is much easyer 
to complicate things.

OK, I would like to have a generic interface for Composing xml.
The Parser usually outputs to events in handler. The Composer should 
start by inputing events into handler and somehow composing string, 
streams, files, etc.

Unfortunately, the more I think the more I realize that it will be much 
better if I give up. :) But, I am not a quieter and I really need this 
kind of library anyway.

I was thinking about the traditional way of processing XML files. In DOM 
we have the following stages:

Parse -> DOM -> Serialize

If we expand this stages with SAX it should look like the following:

XML -> Parser -> SAXHandlerToDOM -> DOM -> Serialize -> XML

As you can see this is oneway pipe. I thought that my library should use 
something similar to the following

XML -> Parser -> XMLTree
                    |
XML <- Composer <--+

If we expand it will look like this

XML -> Parser -> Handler -> XMLTree
                               |
XML <- Composer <- Handler <--+

So this is exactly what I want to achieve. Unfortunately, I don't have 
fresh ideas how to do that.

So, by looking at my parsing code (which is not complete), do you have 
any suggestions how to do that. I believe that you guys have more 
experience than me in this areas and maybe you are aware of some 
techniques which I am not.

Thanks in advance and sorry for the long and not that clear to me email. 
If this email is bothering you please take my apologies and ignore.

That is not true. The single nomination actually triggered a (admittedly
fast) process, where multiple people spoke in favour, not just a single
one. It also followed a discussion on python-list.

I think your impression is wrong (atleast on my part): I did not
deliberately side-step xml-sig; it just didn't occur to me to have the
discussion there also. I implicitly assumed most people on xml-sig would
agree.

Again, your impression is somewhat wrong: Guido first submitted the code
to the SF bug tracker; there I commented that he should discuss it on
xml-sig. I based this recommendation on my view that any such library
should see a wider audience first before being admitted to the core;
this library of Guido had (to my knowledge) not been seen by a wider
audience.

This is unlike ElementTree, which had existed for quite some time, and
collected a lot of community feedback.

Well, this is one of the big problems with XML: there are so many
libraries to chose from, for so many different kinds of applications.
It took me some time to understand what kind of application Guido's
library is targetting - and such an analysis always ends up with
saying "It is like X, but has Y instead".

In this setting, how should we chose a library? In the last round,
it was "let's believe in standards". I personally still believe in
standards, but it appears that the Python community views them as too
bloated.

So as that has more-or-less failed, the next natural approach is
"let's believe in the community". For that, two things need to
happen: the author of the package must indicate that he would like
to see it incorporated, and the users must indicate that they like
the package. Both has happened for ElementTree, but I think it
could happen for other packages, as well.

If it is merely the lack of due process you are complaining about,
and you agree with the result, then IMO nothing would need to be
changed about the result. Discussing it post-factum on xml-sig
might still be valuable.

Martin

Thanks Martin and others for responding.

I full agree that ElementTree has proven to be useful, popular, and stable, 
and probably no one would object to ElementTree being given the endorsement 
that is implicit in its being made a part of stdlib. 

The lack of due process, given that XML-SIG seems to exist largely to provide 
that very service for all things XML in Python, is indeed all I'm complaining 
about. I am happy that for once, there is momentum behind this sort of thing,
and more power to you for that.

My fears are just that 1. XML-SIG is being seen as either irrelevant or as an 
obstacle (perhaps due to the friction between Fredrik and Uche) and are thus 
being sidestepped, and 2. other libs that could/should be contenders (Amara 
and 4Suite are not in this list, by the way) are going to become further 
marginalized by virtue of the fact that people will say "well, we have 
ElementTree in stdlib already, why do we need (fill in the blank)?"

I suppose the same kind of implicit endorsements were given to minidom and 
SAX, and that obviously hasn't prevented people from going out and using 
ElementTree, lxml, etc., so I don't know... I can't predict the future. I'd 
just feel better about it if everyone on XML-SIG, where people hang out 
because they have a definite interest in this kind of thing, knew what was 
going on. Some authors of other libs may not even be aware that they could so 
easily have their code whisked into stdlib, if it's solid enough.

I've CC'd the XML-SIG list on this; discussion should probably continue on 
python-dev since we're well into the xml package at this point.

I'm not entirely sure myself; I've had no real time to look at it for a while.

I think before we need to worry about PyXML from the perspective of the 
standard library, we need to work out a better way to deal with the "xml" 
package.  Not only is the current state a source of confusion for users, it's 
a problem for testing the standard library if there's also a PyXML installed 
for the same version of Python (the PyXML modules are imported instead of the 
stdlib modules, but the tests for the standard library may reflect fixed 
bugs).  This has bit me a few times.

I'd like to propose that a new package be created in the standard library: 
xmlcore.  This package should contain what's currently in the "xml" package.  
The xml package should be replaced with a single module that's responsible 
for the magic that xml/__init__.py deals with now.  The tests for the xml 
package will be changed to test the xmlcore package.

Advantages:

- People who specifically want the standard library code can get it without
  having PyXML get in the way if installed.

- Existing code using the xml package will continue to work.

Risks:

- Pickles containing classes from the xml package will break if we're not
  really careful.  But I think they're pretty fragile now.

I'll be glad to make these or similar changes if there's concensus on this.

If only I'd understood that when I added the xml/PyXML hack to the stdlib 
years ago.  :-(

Fixed now.  I'll deal with the documentation in a few days; I actually expect 
to have some time.

I saw your checkin: wouldn't it be better to keep the xml directory
and xml/__init__.py instead of adding an xml.py module ?

The semantics of a package import are different than that
of a module import, so this may make a difference. I did the
same for the mx packages some years ago (when I moved everything
under the mx package) and then used code like this to make sure
that pickles continued to work as well as have them redirected
to the new package once they were stored again:

DateTime/__init__.py:

# Redirect all imports to the corresponding mx package
def _redirect(mx_subpackage):
    global __path__
    import os,mx
    __path__ = [os.path.join(mx.__path__[0],mx_subpackage)]
_redirect('DateTime')

# Now load all important symbols
from mx.DateTime import *
from mx.DateTime import __version__


Note that in doing so, pickles will get redirected to the new
package. I'm not sure whether that's what you would want for
the xml/PyXML package, though: it would either direct them
to the xmlcore package (bypassing PyXML on systems where it's
installed) or direct them to the PyXML versions (bypassing
the xmlcore package and causing them only to be unpicklable
on systems with PyXML installed).

Almost all XML toolkits will allow you to serialize to a string.  There
are many toolkits you can choose from.  Do you have any other details on
your specific needs?

My recommendation, just pick a toolkit and read its docs to see how to
write XML to string.  You may need to use the cStringIO module, but this
is very easy.

Subject: [XML-SIG] ANN: 4Suite XML 1.0b3
Message-ID: <57ac7f9e0512140605l6fb04d49ibd24d22246b096dc@mail.gmail.com>

Today we release 4Suite XML 1.0 beta 3, now available from Sourceforge and
ftp.4suite.org.

As of the last release (1.0b2) 4Suite is split into three separate packages:

4Suite XML - XML, XPath, XSLT, related technologies and support libraries
4Suite RDF - RDF processing libraries and stand-alone DBMS
4Suite Repository - XML and RDF repository

This is a release of just the first component.

Highlights of changes in 4Suite XML since the last release
------------------

* 4Suite now has native DTD validation for Domlette and Saxlette,
  implemented in C.  PyXML (xmlproc) is no a requirement for validation, and
  thus PyXML is no longer required for any feature in 4Suite.
  For Domlette validation, simply use ValidatingReader.  For Saxlette
  validation, use P.setFeature(xml.sax.handler.feature_validation, True).
  Also new to Saxlette are: DTDHandler, DeclHandler and ErrorHandler.
* New Ft.Xml.Lib.BaseUri function, which attempts to implement the semantics
  of the baseURI DOM Level 3 attribute as a stop-gap until some improvements
  can be made directly in Domlette.
* New Ft.Lib.Uri.Relativize function, which produces context-sensitive
  relative references from absolute URIs.
* Platform fixes for 64-bit Intel/AMD and HP-UX
* Deprecate Ft.Xml.ParsePath and Ft.Xml.Xslt.TransformPath (whose duties are
  now also taken up by Ft.Xml.Parse and Ft.Xml.Xslt.Transform)
* Deprecate category metadata property for XSLT extension elements
* Bug fixes, improvements to performance and documentation

4Suite is a comprehensive platform for XML and RDF processing, with base
libraries and a server framework.  It is implemented in Python and C,
and provides Python and XSLT APIs, Web and command line interfaces.
4Suite XML is the core set of XML, XPath, XSLT, related technologies
and support libraries.

For insulation from Domlette implementation changes, developers should
always use the generic Ft.Xml.Domlette APIs (rather than, say
Ft.Xml.cDomlette).

This is a neat feature, and similar to the append_xml_fragment() method
in Amara.  I do wonder whether it should be the default, though.  As an
example, in Amara the above would set text in that element and escape
the angle brackets.  If you wanted to add child elements you'd have to
do:

doc.definitions.message.append_xml_fragment('<h1>Hei I can assign XML to
elements that will be parsed on the fly.</h1> Good!')

My worry with your approach is that if I want to use such characters in
my regular XML, I'd have to escape them.  Rather than doing:

doc.definitions.message = '100 < 1000'

I'd have to do:

doc.definitions.message = '100 &lt; 1000'

Which seems a bit odd at the content API level?

Yes.  Nice.  What does doc.xml.composestream(stream) do, though?

I'm sorry that I don't have much time to peruse your code.

http://uche.ogbuji.net/tech/4suite/amara
ftp://ftp.4suite.org/pub/Amara/

Changes since Amara 1.1.6:

* Deprecate xml_text_content property
* Add xml_child_text property that concatenates all immediate child
  text nodes (no recursive descent)
* Change unicode coercion for documents and elements to recurse through
  all descendant text (now analogous to XPath's string() coercion)
* Return added or removed node in
  - xml_append
  - xml_insert_after
  - xml_insert_before
  - xml_remove_child
  - xml_remove_child_at
* Update allinone bundle to 4Suite 1.0b3
* Packaging fixes

Amara XML Toolkit is a collection of Python tools for XML processing--
not just tools that happen to be written in Python, but tools built from
the ground up to use Python idioms and take advantage of the many
advantages of Python.

Amara builds on 4Suite [http://4Suite.org], but whereas 4Suite focuses
more on literal implementation of XML standards in Python, Amara
focuses on Pythonic idiom.  It provides tools you can trust to conform
with XML standards without losing the familiar Python feel.

The components of Amara are:

* Bindery: data binding tool (a very Pythonic XML API)
* Scimitar: implementation of the ISO Schematron schema language for
            XML; converts Schematron files to Python scripts
* domtools: set of tools to augment Python DOMs
* saxtools: set of tools to make SAX easier to use in Python
* Flextyper: user-defined datatypes in Python for XML processing

There's a lot in Amara, but here are highlights:

Amara Bindery: XML as easy as py
--------------------------------

Bindery turns an XML document into a tree of Python objects corresponding to
the vocabulary used in the XML document, for maximum clarity.  For example,
the document

<monty>
  <python spam="eggs">What do you mean "bleh"</python>
  <python ministry="abuse">But I was looking for argument</python>
</monty>

Becomes a data structure such that you can write

binding.monty.python.spam

In order to get the value "eggs" or

binding.monty.python[1]

In order to get the value "But I was looking for argument".

There are other such tools for Python, and what makes Anobind unique is
that it's driven by a very declarative rules-based system for binding
XML to the Python data.  You can register rules that are triggered by
XPattern expressions specialized binding behavior.  It includes XPath
support and supports mutation.  Bindery is very efficient, using SAX
to generate bindings.

Scimitar: Schematron for Pytthon
--------------------------------

Merged in from a separate project, Scimitar is an implementation of ISO
Schematron that compiles a Schematron schema into a Python validator
script.

You typically use scimitar in two phases.  Say you have a schematron
schema schema1.stron and you want to validate multiple XML files
against it, instance1.xml, instance2.xml, instance3.xml.

First you run schema1.stron through the scimitar compiler script,
scimitar.py:

scimitar.py schema1.stron

The generated file, schema1.py, can be used to validate XML instances:

python schema1.py instance1.xml

Which emits a validation report.

Amara DOM Tools: giving DOM a more Pythonic face
------------------------------------------------

DOM came from the Java world, hardly the most Pythonic API possible.
Some DOM-like implementations such as 4Suite's Domlettes mix in some
Pythonic idiom. Amara DOM Tools goes even further.

Amara DOM Tools feature pushdom, similar to xml.dom.pulldom, but
easier to use.  It also includes Python generator-based tools for
DOM processing, and a function to return an XPath location for
any DOM node.

Amara SAX Tools: SAX without the brain explosion
------------------------------------------------

Tenorsax (amara.saxtools.tenorsax) is a framework for "linerarizing" SAX
logic so that it flows more naturally, and needs a lot less state
machine wizardry.

License
-------

Amara is open source, provided under the 4Suite variant of the Apache
license.  See the file COPYING for details.

Installation
------------

Amara 1.1.7 requires Python 2.4 or more recent.  If you do not have
4Suite XML 1.0b2 or better, grab the Amara-allinone package.  If you
already have 4Suite XML installed, grab the stand along Amara package.
In either case, unpack to a convenient location and run:

python setup.py install

I don't agree with the change. You just broke source compatibility
between the core package and PyXML.

I can't quite understand why access to a key "0" is being attempted here.

Message-ID: <27182750.1134719662274.JavaMail.ngmail@webmail-01.arcor-online.net>

Looking at Uche Ogbuji?s Amara and David Mertz? Gnosis Objectify, I was impressed by their simple 'pythonic' bindings ? the network of Python objects generated from an XML document reflect the document's (schema's) object model, rather than impose a fixed (meta)model on the data, the way DOM does.  Dave Kuhlman's generateDS does something similar, but starts with an XML Schema rather than an instance document.

These approaches presuppose the existence of XML data (or of an XML Schema in the case of generateDS).

I need to go the opposite direction, however: I have a network of Python objects and need to generate XML from it.  In the past, I have simply persisted my object network using pickle.  This was sufficient until our customer discovered the need to generate reports from this data using (non-python) XML tools, so the idea was born to persist the data as XML document(s).

Xml_pickle immediately sprang to mind .  The problem is that it generates the XML according to a fixed (meta)DTD, like the DOM approach in reverse.  What we really need is a more 'XMLic' approach ;-), i.e. an XML that reflects the object model of our Python object network.  Ideally, this approach should also supply the DTD/XSD/RelaxNG schema (our customer favours XML Schema).

What would be the best way to go about it?  Is there any alternative to xml_pickle that is more 'XMLic'?

AFAIK there are tools that can infer the schema from an instance document, which could be a way of satisfying the second requirement, once we have succeeded in dumping an XML instance document.

I should also mention that our Python classes are modelled in UML using Enterprise Architect from Sparx Systems.  This tool has the capability of generating XSD for a model.  The XSD that it generates for our model would require quite a lot of post-editing, however.

Thanks a lot in advance

Examplotron (http://examplotron.org). It generates RelaxNG schemas
from an instance document. You can use trang to produce DTD or W3C
schemas.

It allows you to specify (with namespaced attributes in the document)
constraints when they are not inferable from the document (for
instance, the fact that an element is optional, something that
Examplotron cannot find itself).

being able to iterate over certain mappings is a relatively new addition
to Python.

if an object doesn't implement the __iter__ hook required for iteration,
the for-loop will call __getitem__ until it gets an IndexError.  any other
error will be propagated to the caller (like the KeyError you get in this
case).

try

    [a for a in n.attributes.keys()]

instead.

Subject: [XML-SIG] elementtree,
	element.text = value problem and a couple other questions
Message-ID: <43A6B1F9.7020807@free.fr>

I just don't get it.

Excerpt from my code:

def addElement(doc, name):
    new = et.SubElement(doc, name)
    return new

def addValueElement(doc, name, value):
    new = et.SubElement(doc, name)
    new.text = value
    new.text = '\n'
    return new

doc_header = """<wine></wine>"""
doc = et.XML(doc_header)
addValueElement(xml, u'name', string.strip(dbItem.winename))
addValueElement(xml, u'additionalname', string.strip(dbItem.winename2))
.... more

But the "value" writing to new.text doesn't show up in the xml file.

<wine><name>
</name><additionalname>
</additionalname><vintage><year>
</year><bottle><size>
</size></bottle></vintage></wine>

What am I missing?

By the way is it possible to write the file in a "pretty" format?

One last question (at least for the moment) is how to get something 
along the following lines into the header/beginning of the file:
<?xml version="1.0" encoding="UTF-8"?>
<?jaxfront version=1.60;time=2005-12-18 12:15:07.078;xsd=wineXML.xsd?>
<wine xmlns="http://www.winexml.org/XMLSchema" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="
</wine>

I added it to my "doc_header" variable but I can't get it to write 
exactly this.

Thanks
Werner

Only about the second one. The first one is the XML declaration, and  
is not considered a processing instruction, despite being  
syntactically extremely similar.

Well, that particular XML declaration is equivalent to not having  
one, since UTF-8 is the default encoding. If the system at the other  
end requires one, then either your MIME types need fixing, or the  
system at the other end is broken.

What's wrong with append here? Does it give the right result, or some  
problem?

The first is an XML declaration, rather than a processing
instruction..  See the XML specification for more info on this:

Just about any file I came acros they have these things in there, so is 
this just overkill or is it a convention that one puts them in.

So, if they were not the default, i.e. if I would use "ISO-8859-1" how would I add them.

I like it at the top of the file and not in the middle.  I was starting 
with a doc containing the root, but I think I am changing this in which 
case I could do this append as the first thing.

Thanks for your hints and sorry if these are stupid questions or are 
answered in the specifications (frankly they are more confusing then 
helpful to me).

I am trying to figure out what tools to use (easy to use, but still 
pretty full featured) and at the same time learn XML.  I was jumping 
between lxml, elementtree and amara and just got more confused along the 
lines.  So, as elementtree will become part of Python, I assume that 
this is happening as it is the best of the crop, I will just use it.

Best regards
Werner

But :-(  it does not work.

If I do this:
pi = et.ProcessingInstruction("twcb version=1.7;xsd=wineXML.xsd")
 >>> wine = et.Element('wine')
 >>> pi.append(wine)
 >>> et.dump(pi)
<?twcb version=1.7;xsd=wineXML.xsd?>

There is no "wine" element.

And if I do this:

 >>> wine = et.Element('wine')
 >>> wine.insert(0, pi)
 >>> et.dump(wine)
<wine><?twcb version=1.7;xsd=wineXML.xsd?></wine>

Then I have it in the middle again (same result with append or insert).

So back to square one.  Is there another way of building the 
document/tree which allows me to put the PI at the top?

Sorry to be a bother
Werner

here's a simple (and only lightly tested) in-place indenter:

def indent(elem, level=0):
    i = "\n" + level*"  "
    if len(elem):
        if not elem.text or not elem.text.strip():
            elem.text = i + "  "
        for elem in elem:
            indent(elem, level+1)
        if not elem.tail or not elem.tail.strip():
            elem.tail = i
    else:
        if level and (not elem.tail or not elem.tail.strip()):
            elem.tail = i

to prettyprint, just call this before you serialize the tree.  (note that
this doesn't work well on documents that contain mixed content).

which can, in fact, be simplified too:

def indent(elem, level=0):
    i = "\n" + level*"  "
    if not elem.text or not elem.text.strip():
        elem.text = i + "  "
    for elem in elem:
        indent(elem, level+1)
    if not elem.tail or not elem.tail.strip():
        elem.tail = i

(however, this is perhaps a bit too clever...)

Subject: [XML-SIG] Ebbeding image data in XML
Message-ID: <43A84E79.4040609@free.fr>

I would like to embed an image in an XML file.

I was thinking of using PIL.tostring() and put it into the imageasstring 
element.

<imagedata>
    <imagemode>RGB</imagemode>
    <imagesize>(540, 982)</imagesize>
    <imageasstring>HERE GOES IMAGE DATA</imageasstring>
</imagedata>

Currently I use lxml.etree and get encoding errors when I write the 
image into the element.

I would like the file to XML Schema complient, so what "xs:" type should 
one use for the imageasstring element?

Any hints as always much appreciated.
Werner

You'll need to encode the imagestring data to base64, and use the
appropriate type.

Hello everybody.
I have a problem with xmlproc.
If I have a dtd in the direcory of this file, the parser send me to

this is the video output:

It works perfectly. The question is: what is the "u" in the elements??
Thanks to all.
below there is my code.


from xml.parsers.xmlproc import xmlproc
import sys

class DTDReporter(xmlproc.DTDConsumer):
    "A simple class that just prints out the events it receives."

    def __init__(self,parser,out=sys.stdout):
        xmlproc.DTDConsumer.__init__(self,parser)
        self.out=out

    def new_attribute(self,elem,attr,a_type,a_decl,a_def):
        self.out.write("ATTRIBUTO: %s - Elemento: %s - Contenuto: %s %s 
- Default:[%s]\n" % (attr,elem,a_type,a_decl,a_def))

    def new_element_type(self,elem_name,elem_cont):
        self.out.write("ELEMENTO: %s - %s\n" % (elem_name,elem_cont))

    # --- Client methods

    def close(self):
        self.out.close()

# --- Main program

if __name__ == '__main__':
    t=xmlproc.DTDParser()
    t.set_dtd_consumer(DTDReporter(t))
    #Si sceglie se parsare il file messo come input da tastiera o se il 
file sul disco. Si puo' dare anche il percorso di localizzazione del file.
    #t.parse_resource(sys.argv[1])
    t.parse_resource("MeshAP2.dtd")

Fundamentally, an XML document is a sequence of Unicode characters,
independent of any encoding. Therefore, when a the contents of a document or
DTD are being read, it is often very convenient for APIs to use Python's
unicode type as a means of reporting what is in the document. That's why the
unicode objects exist for you. (Although, I would not count on xmlproc to be
consistent about returning unicode).

As for why you see them printed as u'...', that's because you are "print"-ing
tuples and lists that contain unicode objects. If you instead print the
unicode objects individually, rather than their containers, then the unicode
strings will be encoded for you automatically to whatever Python thinks your
screen can handle.

>>> print [u'hello world', u'greetings']
[u'hello world', u'greetings']
>>> print u'hello world'
hello world

Which kind of schema? W3C XML Schema? RELAX NG? I assume not DTD since
PyXML has xmlproc and 4Suite XML 1.0b3 has built-in validation.

I'm not sure references to recent W3C standards, pyxml, and
pythonic can really be used in a sentence without negations,
but here's another schema implementation that you might find
interesting:

Message-ID: <8e2a98be0512231222t787ffdd0r3097b5e55045ed99@mail.gmail.com>

Hello all,

I appologize for positing such a trivial question, but I am having trouble
decrypting the python XML documentation.

I am parsing a relatively simple strings, each of which consist of a single
xml tag.  For example:

<user first="jean" last="valjean" dob="17290101" children="1"
hobby="stealing bread" />

What is the best way to determine only the user's hobby?  pulldom, sax,
something else?  is there guidance on using xml tools for single tags?  This
is what I have so far

  from xml.dom.pulldom import *
  a = parseString('<user first="jean" last="valjean" dob="17290101"
children="1" hobby="stealing bread" />')

I've tried getEvent() and expandNode(), but am not getting any closer to
accessing the content in the string.  What are your suggestions on the best
way to retrieve the hobby?  Thank you very much any help.

Hope you all have a happy holiday,
Mike Gilbert

Hello again,

I think I found a way to accomplish my goal with minidom.  Is this the most
direct solution for my goal, or is there a simpler way?  Thanks again.

import xml.dom.minidom

document = '<user first="jean" last="valjean" dob="17290101" children="1"
hobby="stealing bread" />'

dom = xml.dom.minidom.parseString(document)

t = dom.getElementsByTagName("user")[0]

if t.hasAttributes():
    for cnt in range(0, t.attributes.length):
        if t.attributes.item(cnt).nodeName == "hobby":
            print 'hobby = ' + t.attributes.item(cnt).nodeValue

minidom is a good choice because it is part of the standard Python
library.  If you, or your users, are willing to install extra
software, you may want to look at ElementTree and lxml:

- ElementTree: http://effbot.org/zone/element-index.htm

- lxml: http://codespeak.net/lxml/

They are DOM-like, but some consider it a better DOM.

Yes.  But, there may be a slightly more direct way.  minidom
attributes are a NamedNodeMap which is a sort of dictionary-like
object.  So you can use indexing, for example, in your case,
something like:

    t.attributes['hobby']

and also:

    if t.attributes.has_key('hobby'):
        val = t.attributes['hobby']

Use dir(t.attributes) to get a list of other methods.

Hi All,
     I am using libxml2dom for DOM support in libxml2. There are some test examples in the package itself. but when I try to run those sample examples, I face following error:
   
  Traceback (most recent call last):

I am installing libxml_domlib(1.2a) on linux but when I build it it searches for  includes of libxml2 in folder 
  /usr/local/include/libxml2 but  libxml2 have includes under /usr/include/libxml2. For this reason it gives me following error:

  In makefile I changed the places for libs and given the correct path for includes of libxml2 under INCL_DIR instead of that its picking up /usr/local/include/libxml2 and searches headers there . the makefile(afer chages) I am using is following:

Subject: [XML-SIG] PyCon TX 2006: Early-bird registration ends Dec. 31!
Message-ID: <43B2AB53.1000409@python.org>

Early bird registration for PyCon TX 2006 ends on December 31st,
so there are only a few days LEFT. To register, please visit:

	http://us.pycon.org/TX2006/Registration

You can still register after Dec. 31st, but the cost will go up by
US$65 (US$25 for students).

This year PyCon will feature a day of tutorials before the three days
of regular presentations.  Course outlines for all the tutorials have
been posted; see

	http://wiki.python.org/moin/PyCon2006/Tutorials

All of the PyCon tutorials are still open for new registrations, but
space is limited, and we suspect they'll all be filled up by the time
early-bird registration closes.

Don't forget to book your hotel room, too.  PyCon TX 2006 is being
held at a Dallas/Addison hotel, and we have negotiated a special low
rate:

Message-ID: <20051228160237.26673.qmail@web54115.mail.yahoo.com>

I am having problem with parsing CDATA section. I am using PyXml and minidom for parsing the xml document. 
  My motive is to get the data back in the same format in one string as it is writen in xml file. Here is the sample:
  --
  <StateChg>
      <![CDATA[
                check.. its cdata section
  
                 all data is printed in it s format
                 ]]>
<StateChg>
  --
  put when I print all its childs using:
  ---
   print StChg.childNodes  #StChg. is instance to <StateChg> element
  --
  It gives following output
  --
  [<DOM Text node "\n">, <DOM Text node "\t\t\t\t \t">, <DOM Text node "\n">, <DOM Text node "\t\t\t\t\t chec...">, <DOM Text node "\n">, <DOM Text node "\t\t\t\t\t all ...">, <DOM Text node "\n">, <DOM Text node "\t\t\t\t\t ">, <DOM Text node "\n">, <DOM Text node "\t\t\t\t\t">]
--
   
  The output Shows it is text node but we had declare it as CDATA_SECTION_NODE.
   
  and also the output is not desired ( format lost and some data is lost), 
   
  Why its happening. What I have to do to get the same output as in xml with the format and indentation.
   
  Please,correct me, where I am wrong

You might be interested in the "normalize" DOM method: it combined
adjacent text nodes into a single one.

In XML, you have the logical constructs: elements, attributes, character data,
processing instructions, and comments. You use markup to represent these
constructs. And you are currently using the DOM API to access an abstract
representation of them -- an implicit tree of nodes.

At the markup level, a span of character data can be written using either (1)
literal characters, numeric character references, and entity references, or
(2) a CDATA section, consisting of literal characters only, bounded by start
and end markers. There is no semantic difference between the two ways of
writing character data; it is just two different ways of writing the same
thing. Thus "1 &amp; 2 are &lt; 3" in regular markup is exactly the same as "1
& 2 are < 3" in a CDATA section.

It is common for a parser to report each span of character data separately. It
may say "this character data was written using a CDATA section" and "this
character data was written with regular markup"; or it may just say "I saw
this character data, and then I saw this other character data". It is also
possible that character and entity references in the markup will be treated as
separate spans of character data. Very long spans might be split as well. 

Consequently, in both the SAX and DOM APIs, these separate reports from the
parser *may* manifest as separate, subsequent 'characters' events (in SAX) or
as separate Text nodes (in DOM). You must be prepared to see them in chunks.

You must also realize that it is not incorrect to see CDATA sections as Text
nodes in an implementation that only supports the Core Interfaces of DOM.

DOM does have a CDATASection node, which is a subclass of Text, but it is only
in the Extended Interfaces, which are optional. So if an implementation
chooses to support DOM's Extended Interfaces, then CDATA will manifest as
CDATASection instead of Text.

CDATASection nodes are in fact supported in newer versions of minidom, despite
the docs at http://python.org/doc/2.4.2/lib/minidom-and-dom.html which say
otherwise.  These nodes and some of the other extended interfaces blur the
distinction between lexical markup and logical constructs that the markup is
intended to represent, so they actually make things more difficult for users,
typically, which is why they're optional.

As Dieter Maurer pointed out, you can merge adjacent Text nodes by calling the
normalize() method on any ancestor of the nodes. However, by design, this only
works on Text nodes, not CDATASection nodes, as per DOM requirements.


Python 2.2.3:
>>> from xml.dom.minidom import getDOMImplementation, parseString
>>> impl = getDOMImplementation()
>>> impl.hasFeature('Core', '2.0') # core interfaces?
1
>>> impl.hasFeature('XML', '2.0')  # extended interfaces?
0
>>> doc = parseString('<test>1 &amp; 2 are &lt; 3 ... <![CDATA[1 & 2 are < 3]]></test>')
>>> doc.childNodes[0].childNodes
[<DOM Text node "1 ">, <DOM Text node "&">, <DOM Text node " 2 are ">, <DOM Text node "<">, <DOM Text node " 3 ... ">, <DOM Text node "1 & 2 are ...">]
>>> doc.normalize()
>>> doc.childNodes[0].childNodes
[<DOM Text node "1 & 2 are ...">]
>>> doc.childNodes[0].childNodes[0].data
u'1 & 2 are < 3 ... 1 & 2 are < 3'


Python 2.4.2:
>>> from xml.dom.minidom import getDOMImplementation, parseString
>>> impl = getDOMImplementation()
>>> from xml.dom.minidom import parseString
>>> impl.hasFeature('Core', '2.0') # core interfaces?
True
>>> impl.hasFeature('XML', '2.0')  # extended interfaces?
True
>>> doc = parseString('<test>1 &amp; 2 are &lt; 3 ... <![CDATA[1 & 2 are < 3]]></test>')
>>> doc.childNodes[0].childNodes
[<DOM Text node "1 & 2 are ...">, <DOM CDATASection node "1 & 2 are ...">]
>>> doc.normalize()
>>> doc.childNodes[0].childNodes
[<DOM Text node "1 & 2 are ...">, <DOM CDATASection node "1 & 2 are ...">]
>>> doc.childNodes[0].childNodes[0].data
u'1 & 2 are < 3 ... '
>>> doc.childNodes[0].childNodes[1].data
u'1 & 2 are < 3'


If you need to merge adjacent CDATASection nodes and/or mixed Text and
CDATASection nodes, there are no functions built-in to do that. You'll have to
roll your own. There's no way to disable the creation of CDATASection nodes in
minidom.

Anyway, you should not expect to be able to precisely reproduce or even know
exactly what was in the lexical markup in your original, unparsed document
when you run it through a parser, and especially not after you access the
parser's reports through a relatively abstract API like DOM or SAX or the
XPath tree model. You can produce XML that *means* the same thing as the
original, but you're not going to get XML That *looks* exactly like the
original. If you expect to do that, then you shouldn't be running your XML
through a real XML parser at all.
