True.  I probably misunderstood the question.  Once you run normalize(), 
you don't have whitespace-only nodes in content anymore (unless the 
content is only whitespace, that is) - those nodes have been absorbed 
into other content nodes.

The Python interpreter is interpreting the backslashes before it gets
passed to pxdom.parse(). In particular, '\b' is seen to be the backspace
character (ASCII code 8) and treated as such.

You need to pass in "proxy_pxdom_xpath\\basedataschema.xml" or use raw
strings: r"proxy_pxdom_xpath\basedataschema.xml"

Yes, but whitespace-only nodes are very common in XML formatted for 
human consumption e.g.

<foo>
	<bar>Hello</bar>
	<bar>Hi</bar>
</foo>

I count 3 whitespace-only nodes (even after normalize). Those nodes are 
not useful to the application some I'm wondering about the canonical 
way of removing them (without writing the [admittedly simple] code myself).

  Seems the HTML parser has no notion of Processing Instruction,

I remember submitting a patch for this some time ago. Whilst doing some
XPath experimentation, it did occur to me that the xml.xpath package
could
do with some tidying up in certain respects, but I never got round to
looking into this more thoroughly. As for the exception you see, I
suspect
that some refactoring process which changed the representation of
certain
things left some corner cases that didn't get tested.

Hi there,

We are running a program using Python 2.3, pulling XML data from a server. All goes well if the data does not have a lot of entries. If it does all of a sudden there is a number in data; almost like a line number.
Below an example, I cutted some ReturnMessage tags because it takes a quite a few to get the line number but you get the idea...

----Example-----

<?xml version="1.0" encoding="UTF-8"?>

<MessagesWaiting>

<ReturnMessage id="98298996" />

<ReturnM
1000
essage id="98298997" />

<ReturnMessage id="98298998" />

<ReturnMessage id="98299132" />

<ReturnMessage id="98299167" />

2000

<ReturnMessage id="98299209" />

</MessagesWaiting>

Other users using the same server as we pull the data off don't have the problem; but they are not using Python...

Obviously Python can't use this mallformed data. I have an idea it has something to do with the http connector or so but are really in the dark what.

Anybody any ideas what it can be and how to resolve it?


Kind regards,

Pieter Smits

Here are some approaches that can be applied generally; your application may 
be able to use something more specific.

- Don't remove them, just ignore them.  How easy this is depends on how you 
application processes the DOM.  getElememtsByTagName() (and the 
namespace-aware varient) may help here.

- Use a DTD so the parser can determine which whitespace exists in element 
content so it can avoid adding them to the tree, and your initial example 
shows you tried.  This *requires* a DTD.

- Use a node filter that discards Text nodes in element content.  This 
requires that your filter knows enough about the document type you're 
expecting that it can identify whitespace in element content.

There are probably other approaches as well.

I an doing this now but the DOM that I am working with makes this very 
annoying. There are a lot of nodes where the next sibling element is 
relevant. I have a lot of calls to _skip_ws_nodes().

It's not my XML and I don't have a DTD for it.

I'll look into that.

So StripXml is not expected to work in this context? The problem seems 
to be that StripXml expects documents to have a createNodeIterator 
method and DOMBuilder is not creating a DOM that offers that method. 
Not sure why this is...

are those numbers authentic, or did you just make some 4-digit numbers up?
it could be HTTP chunking, in which case the server splits the response up in
parts, each of which is preceeded by the part size in bytes, where the size is
given as a hexadecimal number.  for details, see:

    http://www.w3.org/Protocols/rfc2616/rfc2616-sec3.html#sec3.6.1

what library are you using to talk to the server?

Note that in the elementtree model, most of those disappear into the "tail"
attribute.  No need to write code to skip over whitespace nodes; just get
the "bar" element's "text" attribute and you're done.

If you don't have a DTD (or the functional equivalent), then you're out 
of luck, because in that case the machine doesn't having any way of 
knowing what you mean by "insignificant whitespace."  You don't want the 
software to assume that every text node which contains only whitespace 
is insignificant, even if you have "normalized" the document to collapse 
adjacent text nodes into one.  Consider:

<Diagnosis>... the <Glossary id='1234'>cancer</Glossary> <Glossary
id='2345'>patient</Glossary> requires ...</Diagnosis>

Would you *really* want the presentation of this text to omit the space 
between 'cancer' and 'patient'?

If you *know* that the documents will never contain such inline markup
(because, for example, you've had a peek at the elusive DTD, and have
been assured that it won't change), then you can write software to take
advantage of this special knowledge.  Probably the most straightforward
approach would be an XSLT script with a template that strips whitespace
text nodes and another template which passes everything else through
unscathed.

Message-ID: <1094064093.7809.6.camel@localhost.localdomain>

Hi there,
I am using DOM to read an external DTD and then create and fill a
corresponding document. Then I save the result with PrettyPrint.My
problem is that the resulting XML file has the name of the external DTD
which is fine, but I would rather have the DTD copied in extenso, id est
transforming the external DTD into an internal one.

I did not find the way to do that easily. Can someone help me?

hi!

Is it possible for me to compile and use cDomlette for a different
platform. can i compile using embedded visual c++. Or does it rely on some
native system calls which wont work on a PDA?

thanks

If you reread my original post, you'll see that I am not arguing for 
different default behavior. I was asking if there was some way of 
removing all whitespace-only text nodes. StripXml() claims to do what I 
want but it doesn't work with the DOM created by DOMBuilder (this seems 
like a bug or misdesign).

How could I correctly manipulate the DOM without making assumptions 
about it's semantics i.e. if whitespace-only nodes were to suddenly 
become significant, how could I correctly process them without some 
knowledge of their meaning?

I just wrote a trivial little function to do this. The cookbook recipe 
is here: http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/303061

Subject: [XML-SIG] several XML newbie questions
Message-ID: <11C0F3AA5F32EB3D52557F71@[192.168.2.201]>

I've been programming with Python for a few years now.  I've written a lot 
of CGIs for customers in which I've used either the DocumentTemplate or TAL 
modules from Zope to produce output from templates.  I've decided it's 
probably time for me to move on to using XSL for templates instead.

One of my first questions is, which modules should I be using for this? 
The information page about this mailing list suggested PyXML, but that 
module doesn't do XSLT, does it?  (At least, XSLT isn't mentioned on the 
project's SourceForge page.)  If PyXML does do XSLT, is that module 
recommended over the libxml2/libxslt combination?  How about 4Suite?

I don't necessarily need to use whatever the "best" module is right now. 
I'd be happy to use a more "standard" module that may be imperfect.  As 
long as it does what I need, I don't mind waiting for more features in the 
future.

I've been reading "Python & XML" by Jones and Drake.  It's a pretty good 
book, but it needs to be updated.  For example, I've found that the 
examples that use 4Suite don't work as written.  I understand that change 
will happen, but I hope that O'Reilly will publish a new edition of the 
book.  What other books would you folks recommend?  As I said, I'm mostly 
interested in XSLT and a Python slant on the subject would be nice.

Thanks in advance!

Hello.

 

This might be an trivial question, bet feel free to help a newbee :-)

 

XML:

          <subject>TODO</subject> 

          <body>xxx</body> 

 </appointment>

 

My stupid code:

 

doc = xml.dom.minidom.parse(inXML)

tagSubject = doc.getElementsByTagName('subject')

for subject in tagSubject:

  content = subject.nodeValue

  print content

 

Ok so why can I not see the the text "TODO"??

I have tried many similar approaches, but it just want work.

If someone can help me, I would become a happy man!

A common mistake when just starting out: the "TODO" string is the
content of a child of the subject node -- the child is a text node. In
this case, it is the first and only child, so you really want to be
looking at subject.firstChild.nodeValue, instead of subject.nodeValue.

  Question mark are fine in attribute value. but you still have an unescaped

Sorry for disturbing. This link really is generated dynamically by python
and is a bit more complicated than this posted below. I haven't notice
that one of ampersats was not changen into &amp; (In my example link there
was the same problem, one & remained). I was trying to find solution for
few hours (please, do not laugh :)) but just posting on your mailing list
enlightened me. Thank you.

As far as I know, it's pretty standard C lib (plus Python extension
lib).  Of course Expat is the big unknown for me.

I'd suggest trying it and reporting any errors.  We'll fix what we can
as portability issues.

XML 1.1 is fairly new and i know of no Python tools that support it
yet.  Personally I recommend that people wait a good while before making
the move to XML 1.1.

This is a bug that was reported a month ago or so.  The main problem is
that the XPath implementation in PyXML has fallen a long ways behind the
code in 4Suite, and no one has the spare cycles for a re-merge.

StripXml only works on 4DOM nodes :-(

I usually use simple generator code for this sort of thing.  See

http://www.xml.com/pub/a/2003/01/08/py-xml.html

Using domtools from that article, or a more recent version of the
module:

http://cvs.4suite.org/cgi-bin/viewcvs.cgi/Scimitar/domtools.py

You could do something like (untested):

doc.normalize()
ws_only_nodes = domtools.doc_order_iter_filter(
  node, lambda n: n.nodeType == Node.TEXT_NODE and not n.strip()
)
for node in ws_only_nodes:
    node.parentNode.removeChild(node)

I think the XPath impl in PyXML only uses C for the boolean type.  If
you're on Python 2.3+, you could easily tweak it to use the built-in
bool instead.

Also, ElementTree is pure Python and offers partial XPath support.

Subject: [XML-SIG] PyOOTools - Request for Announcement,
	Testing and Bug Reports
Message-ID: <413D5942.4020008@t-online.de>

I just released an alpha version of a python class library:

PyOOTools - Process OpenOffice.org Writer Files and transform them to 
PDF without installing OpenOffice.org
=>
     *  Make serial letters and reports from templates in the SXW-Format 
and store them anew as SXW-Files
     * Extract the pure text information from the SXW-Document and store 
it in a plain text file or a PDF-File
     * Perform simple transformations from SXW-Files to PDF-Files 
without installing OO - for example on a webserver

It contains about 1300 lines of python code and uses the 
ReportlabToolkit, the Python Imaging Library and the XML-Sax-Parser from 
the Standard Library.

As far as I know there is nothing comparable in Python yet. Could you 
list it in your SIG list of Python XML Tools?

The library is found here:
http://www.bezirksreiter.de/PyOOTools.htm

Thanks and greetings,
Martin Simon

hi!

in my code, i am giving make_parser the name of the parser i'd like to use
the code is below

parser = make_parser(['xmlproc'])
parser.setFeature(feature_namespaces, 0)
dh = FindIssue()

# Tell the parser to use our handler
parser.setContentHandler(dh)
# Parse the input
f = open('\um\proxy\policy-eg1.xml')
str = f.read()
f.close()
print "file read"
parser.parseString(str)

this throws an error saying ExpatParser instance has no attribute
'parseString'

what am i doing wrong? i thought i was using xmlproc

thanks

cheers

No, Uche is saying that a bug that was reported last month might be fixed in 
4Suite (Ft.Xml.XPath), but probably not in PyXML (xml.xpath).

Nowadays, _xmlplus (xml.* replacements & extensions) are only installed by 
PyXML. When PyXML installs XPath support in xml.xpath, it is installing the 
4Suite 0.11.1 XPath implementation, which is 3 years old this month.

4Suite 0.11.1, if you installed it separately, also installed its XPath 
implementation in xml.xpath, so for a time there was no difference between 
installing PyXML --with-xpath, and installing PyXML --without-xpath and then 
adding 4Suite later.

After 0.11.1, 4Suite's implementation moved to Ft.Xml.XPath and kept on 
improving (and kept on becoming increasingly incompatible with minidom). But 
PyXML's xml.xpath is still pretty much unchanged from 3 years ago. Well, there 
may be a few patches here & there, but it definitely has not kept up with 
4Suite.

The hope is (or was) to re-merge 4Suite's implementation into PyXML as an 
updated xml.xpath. This may have become a much more daunting task now that 
minidom and Domlette have diverged so much.

> apart from doing a traversal myself, is there a way around it?

Probably not, if you have to use PyXML's implementation.

the error does not appear if i use expat.

Just to be sure, the bug was reported WRT PyXML's XPath, not that in
4Suite.  Back then I checked the problem expression in 4Suite and it
worked fine.  So it probably hasn't been a bug in 4Suite for years.

Actually, I think there's a patch on this.  I really need to carve out
some time to work on my PyXML tasks.

Message-ID: <20DA376D0C991745A4D5249F7BCD7A2521B42C@largo.campus.ncl.ac.uk>

Dear All,

Problem:
Example xml file:
<aaa>
	<bbb />
	<bbb />
<aaa>

I want to replace a part of the xml file, identified by an xpath
construct with something else. For example, 
replace //bbb[2] with <ccc />
To get 
<aaa>
	<bbb />
	<ccc />
<aaa>
 
Is this possible with pyxml & xpath? If not, can anyone suggest what
would be the best way to tackling this problem.

Thanks

You thought wrongly, and it's easy to check:

>>> from xml.sax import make_parser
>>> print make_parser(['xmlproc'])
<xml.sax.expatreader.ExpatParser instance at 0x553e56ac>

clearly expat

>>> print make_parser(['xml.sax.drivers.drv_xmlproc'])
<xml.sax.drivers.drv_xmlproc.SAX_XPParser instance at 0x553e590c>

clearly xmlproc

make_parser falls back to its defaults if none of the drivers you list
can be imported.

the xpath construct would give you a single node or a list of nodes.
get the parent node, remove the current child node and add the node you'd
like to have instead.

You've got some odd code here.  The following works for me (no errors):

>>> from xml.sax import make_parser
>>> parser = make_parser('xml.sax.drivers2.drv_xmlproc')
>>> ruleSet = parser.parse("foo.xml")

Where "foo.xml" is the file I pasted in from your message.

Message-ID: <1094792329.26934.11.camel@ws14.commsecure.com.au>

Hi guys,

We are about to start working on a project that will involve having to
do some (correctly implemented) XML signing and encryption work. I do
not have any real experience with Python libraries for doing this.

Can anybody share some real-world war stories about doing this sort of
thing in Python? My normal method -- find one of Uche's articles where
he has written about this -- does not seem to be working this time.

My "if all else fails" plan is to use the xmlsec library (on top of
libxml2) and write Python bindings if needs be, since I quite like the
library. But I would rather use something with proven bindings if
possible.

Cheers,
Malcolm

I don't have direct experience on the topic.   A friend (Larry Bugbee,
are you on this list?) has been expeimenting with pyxmlsec.  
   http://labs.libre-entreprise.org/projects/pyxmlsec/

When I last looked, it was a lot of special-purpose C extensions.   
That bothered me because of the opportunities for security-damaging
bugs.   I recommended using libxml2+xmlsec and putting SWIG-based python
bindings on that (as you suggest).

i should have put my import statements. i am actually trying to use minidom
with xmlproc. thus the code really is
from xml.dom.minidom import parse
from xml.sax import make_parser

parser=make_parser('xml.sax.drivers2.drv_xmlproc')
ruleSet = parse('foo.xml', parser=parser)

this throws the error i described earlier for the document which i also
posted earlier.

so what am i doing wrong?

A bug in a C extension.

It returns "NULL" (indication of an error) but it did not
set any exception (telling Python about the kind of error).

Almost surely, "xsltSaveResultToString" is to blame.

I don't think you're doing anything especially wrong.  This looks like a
bug in pulldom.  Seems as though it can't handle "global" attributes
when fed from parsers that don't report namespace prefix mappings.

IOW, 

<p3p:PURPOSE appel:connective="or">
             ^^^^^^

breaks in this case.

This will probably require some work in PullDOM to address :-(

Man, you seem to have the worst luck here.

Sure you can do this with pyxml and xpath.  I personally would probably
use XUpdate if I had many such types of replacements to do.

Sorry, the closest I've come to the topic is c14n.

Doesn't libxml2's xmlsec lib already have Python bindings?  I thought
the whole library was wrapped?

The LBL folks are doing xmldsig and xmlenc; not sure what they're
planning on doing for the actual crypto.  You can probably ask them on the
pywebsvcs-talk list at SourceForge.

Aleksey's package is built on libxml and is high quality.  I believe
someone did python bindings to his package.  The python bindings to libxml
are stable, but (as Uche has pointed out) not very pythonic, making you
worry about memory management too much.

m2crypto has an excellent swig-based wrapping of openssl.  you could use
that as a starting point for your own dsig, etc., implementation.  but
getting the c14n right will be very hard.  (I know, I've done it three
times, including a free python version with the editor of the dsig spec;
it's part of pyxml.)

Hope this helps.

The xmlsec library is a separate project. It does not ship with Python
bindings. There are some bindings at sourceforge for it, it appears, so
I need to look at them more closely.

Subject: [XML-SIG] XML Dom question
Message-ID: <20040914142211.GA31226@spock.fcs.uga.edu>


I am trying to insert a new element and value into a XML Dom structure
and am having some trouble.

When I read the file in from disk, I have this:

    <object name='menu__File__Exit' class='wxMenuItem'>
      <label>E_xit</label>
      <event class='EVT_MENU'>On__File__Exit</event>
    </object>

When I run this code:

        w = walker.currentNode
	if "menu__File__Exit" == name and 0 == needs_value and 0 == test:
		myNode = doc.createElement("shortcut_key")
		myNode.setAttribute("modifier","SHIFT")
		w.appendChild( myNode )  
		test = 1

I get this result:

    <object name='menu__File__Exit' class='wxMenuItem'>
      <label>E_xit</label>
      <event class='EVT_MENU'>On__File__Exit</event>
      <shortcut_key modifier='SHIFT'/>
    </object>

This is what I really want:
      <shortcut_key modifier='SHIFT'/>F4</shortcut_key>

Can some one post code on how to do this?  I tried creating a new Node
(called newNode) and setting the nodeType and NodeValue and the use
the appendChild() method, but I keep getting this error:

code:
myNode.appendChild(newNode)

error:
AttributeError: Node instance has no attribute 'childNodes'

Any help would be greatly appreciated!

Thanks,
-John

With the DOM, you have to create a text node and set its nodeValue to 
the  desired content.  Then you can appendChild() it to its to-be-parent 
node.

Message-ID: <414A96A1.40509@t-online.de>

Hi all,

since no XML schema validator seems to be available for Python,
I started to write my own.
The validator uses minidom or elementtree (Fredrik Lundh).
A very first version can be found at http://www.leuthe.homepage.t-online.de.

One drawback of the current release is that no line numbers are 
displayed for the error messages.
How can I retrieve the related line number for a DOM node or an 
elementtree node?
Start AND end line number where the node is located in the XML file 
would be best.

Who can help?

Thanks,

Roland

  libxml2 python bindings now include access to libxml2 W3C Schema
support. This is a work in progress, but considering the "complexity"
of Schemas structure, not surprizing. The Schemas types support is
complete though.

Message-ID: <1095566323.414d03f3076d8@www-mail.usyd.edu.au>

hi!

i have an xml document and would just like to get information placed in a
certain tag. I am thinking of using SAX with a content handler which then
handles the particular tag.
the tag will most likely appear at the start of the document. Is it
possible to stop the document parsing after i receive the tag? how would i
do it?

thanks

cheers

here's one way to do it:

class Found(Exception):
    pass

class MyContentHandler(...):
    def startElement(self, name, attrs):
        if name == "some tag":
            raise Found("some information")

...

try:
    parser.parse(data)
except Found, value:
    # found it
    print value

(this returns the value inside the exception instance.  it might be better
to attach it to some other object (such as the parser instance), but I'm
too lazy to figure out how to access the parser from inside the content
handler...)

Message-ID: <5.2.0.9.1.20040920164957.0240e4f8@127.0.0.1>

I have tried without success to install the latest (0.8.3 and 0.8.2 for 
Python 2.2,
and 0.8.3 for Python 2.3) versions of pyXML. I have obtained the files from 
various
different download mirrors and also tried the installation on two different 
WinXP machines.

I come up against the same problem each time:
the executable simply does not install the package!?

After allowing me to choose a few directory details (the defaults are fine),
it goes to the 'installation in progress' stage, but just sits there doing 
nothing!
'Cancel' exits.

I have not had difficulty with other software installation on these machines
(even today!) so could something be wrong with the pyXML distribution files?

Can anyone help?

works for me (on fedora, using a fresh build).

$ ./python
Python 2.3.4 (#1, Sep 20 2004, 12:46:02)
>>> from elementtree.ElementTree import Element, SubElement, dump
>>> elem = Element("window")
>>> dump(elem)
<window />
>>> from elementtree.ElementTree import VERSION
>>> VERSION
'1.2'

$ ./python elementtree-example-1.py
<window />

note that the error occurs in the regular expression compiler.  my guess is that
you've accidentally modified the ElementPath file in some strange way.  here's
what the offending pattern looks like on my machine:

xpath_tokenizer = re.compile(
    "(::|\.\.|\(\)|[/.*:\[\]\(\)@=])|((?:\{[^}]+\})?[^/:\[\]\(\)@=\s]+)|\s+"
    ).findall

does the elementtree selftest.py script work on your machine (you should get
a deprecation warning followed by "246 tests ok").

Subject: [XML-SIG] Ignoring white-space in Dom trees
Message-ID: <FBB356A6-0CD1-11D9-87DA-000A95E35E1E@jameskingexpress.co.uk>

Hi,

I'm parsing XML documents into Dom trees and then trying to manipulate 
the XML. In short, I'm having trouble traversing the child-nodes in the 
tree due to unwanted white-space text-nodes.

In more detail:
The XML documents that are parsed into the DOM look like this sample 
below:

<root>
	<chapter>
		<page>Lorem ipsum</page>
	</chapter>
	<chapter>
		<page>Lorem ipsum</page>
	</chapter>
</root>
	
I'm using 4Suite's Domlette to parse this XML. The relevant Python 
script is below:

###############

from Ft.Xml.Domlette import NonvalidatingReader
from Ft.Lib import Uri
from Ft.Xml.Lib.Print import PrettyPrint

docUri = Uri.OsPathToUri("doc.xml")
domlette1 =  NonvalidatingReader.parseUri(docUri)

nodeList = domlette1.childNodes

#### If I make a copy of the root node and then print it ...
clnd = nodeList[0].cloneNode(1)
print clnd

#### ... I get something like this result:
#### <cElement at 0108DA30: name=u'root', 0 attributes, 5 children>

################

The 5 children include the 3 text nodes that are made up solely by the 
white-space characters between the <chapter> elements. I'm only 
interested in the chapter elements and I don't want to have to worry 
about the haphazard whitespace-only text nodes that may or may not be 
there.

My Questsions:
Is there a way exclude these nodes from the Dom; something like an 
ignore_whitespace setting for the 4suite Domlette? (something like the 
ignoreWhite property for XML objects in Flash Actionscript) Otherwise, 
are there other python Doms that ignore these whitespace nodes by 
default? Or has anyone got a work-around for this problem?

I may be missing something obvious, I'm very new to python.

Thanks in advance if anyone can help.

James

Yes indeed, and this question was asked 2 days ago on the 4Suite list,
coincidentally. Please see

http://lists.fourthought.com/pipermail/4suite/2004-September/012895.html

You just need to set the stripElements argument in the InputSource
constructor or the XML reader parse method. It's a list of 3-tuples,
not very well documented, but just follow the example.

documents using XSLT style sheets. In our XSLT we have something like:
	<script type="text/javascript" src="menu.js">
		// Some stuff
	</script>

If we use the doctype-public and doctype-system attributes on the  
xsl:output element like so:
	<xsl:output method="xml" indent="yes"
	     
doctype-system="http://www.w3.org/TR/xhtml1/DTD/xhtml1- 
transitional.dtd"
	    doctype-public="-//W3C//DTD XHTML 1.0 Transitional//EN" />
the XSLT parser insists on making the text within the <script> a CDATA  
section (in spite of the XHTML spec saying the <script> elements a  
PCDATA):
	<script type="text/javascript" src="menu.js"><![CDATA[
		// Some stuff
	//></script>

We need to both include script text within the output document and  
`include' external JS files (using an src attribute or whatever). For  
some reason, we just can't get it to work (in a browser) without  
removing the doctype-public and doctype-system attributes from  
<xsl:output>. Does anyone have any suggestions?

Also: for some reason the XSLT processor modifies the content attribute  
of a <meta> element (that is specified in the XSLT):
	<meta http-equiv="Content-Type" content="application/xhtml+xml"/>
if turned into:
	<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
How do I make it stop and why is it doing it?

Finally: we are using libxml2 and libxslt because we had to abandon  
4Suite due to instability. Are there known problems with using 4Suite  
with ModPython and Apache 2? We had a range of problems (complaining  
about the expat version 'til we recompiled Apache, Apache SEGFAULTing  
when trying to do XSLT processing, etc) which suggest to me at least  
that there are some problems with the way 4Suite does things.

Cheers,
Thomas Sutton

  It does it because the spec suggests it:
  http://www.w3.org/TR/xhtml1/#h-4.8

> Also: for some reason the XSLT processor modifies the content attribute

  That's also what the spec suggests:
  http://www.w3.org/TR/xhtml1/#C_4
but I agree overriding the content type is problematic, it should just fix
the charset, that should be fixed.
  Anyway proper place to discuss this and report libxml2 bugs is not this
list, see http://xmlsoft.org/bugs.html

Wa that really intended as a general purpose suggestions? In any case,
when this is done, we have strange problem occur (i.e. the browser
doesn't appear to use the script) and I have been unable to find the
appropriate information with google.

The main reason I asked here is that I am trying to do XSL
transformations from Python. I see libxml2 and libxslt as being
incidental in that, had we not run into problems with 4Suite, we
[probably] wouldn't be using them. I shall though, join the appropriate
libxml2 and libxslt list/s and pose my questions there.

Thanks for the suggestions,
Thomas Sutton

Message-ID: <1096421745.4009.4217.camel@borgia>

http://uche.ogbuji.net/tech/4Suite/scimitar

Scimitar is an implementation of ISO Schematron that compiles a
Schematron schema into a Python validator script, making it a
faster and somewhat more flexible approach than the usual XSLT
implementations.

http://www-106.ibm.com/developerworks/edu/x-dw-xschematron-i.html
http://www.ascc.net/xml/resource/schematron/schematron.html

Schematron is an XML schema language in which you express a set of rules
that the document must meet, rather than expressing a full grammar for
the XML vocabulary (which is the more common approach to XML schemata).
It is by far the most flexible XML schema language available.

Scimitar now support all of the draft ISO Schematron specification.
It will go through a mostly-bug-fix phase until the 1.0 release.
See the TODO file for known gaps in Scimitar functionality and
convenience.

Scimitar is open source, provided under the 4Suite variant of the Apache
license.

The compiler program runs standalone on Python 2.2 or more recent,
although if you are using an earlier version than 2.3, you must also
install Optik 1.4.1 or more recent.  In addition to the above
requirements
the generated validators require 4Suite 1.0a3 or more recent (really
only tested with latest 4Suite CVS).
