Thanx a lot. ElementTree library works perfectly for me.

But I still have a problem. Is ElementTree considered hardrock stable? I
have a "memory protection violation" error after parsing about 60MB of xml
file.

Subject: [XML-SIG] python xml parser
Message-ID: <c22ttm$vjm$1@sea.gmane.org>

How can I pass stdout of processes, or output stream of network channels 
(like ssh) to a python xml parser (either through DOM or SAX) so that 
xml can be used as the communication tool among different components of 
the software? I think the standard python xml reader expects a file-like 
  object or string as the input, but not sure if it can take a stream. 
Any suggestions are highly appreciated.

If you're not passing large amounts of data around, httplib looks pretty 
easy to hook up:

# Pretty much straight from the Library Reference:

import httplib
conn = httplib.HTTPConnection("www.python.org")
conn.request("GET", "/index.html")
r1 = conn.getresponse()
data1 = r1.read()

# pass data1 to an XML processor's parseString() or similar method
# exercise for the reader ;-)

conn.close()

Hi, my name is Matt and I have a question reguarding

You need gcc compiler to build the new code.

The minidom parser in the Python standard library will take a file
name or a file object.  From
http://www.python.org/doc/current/lib/module-xml.dom.minidom.html:

    parse(filename_or_file, parser)
        Return a Document from the given input. filename_or_file
        may be either a file name, or a file-like object. parser,
        if given, must be a SAX2 parser object. This function will
        change the document handler of the parser and activate
        namespace support; other parser configuration (like setting
        an entity resolver) must have been done in advance.

J. Xu -

Yes, as you guessed and as Dave mentions, a file-like object is all you need
on the XML reading side.

You can obtain the stdout stream of a process as a file-like object when you
create the process via os.popen(), os.popen2(), os.popen3(), os.popen4() --
see the os module docs for info on how to use those functions.

The method for obtaining a file-like object that wraps a network stream will
depend on the library/software you are using. It may provide an API that will
give you a file-like object, or a socket object, or it may not give you any
hooks at all.

Your task will be to figure out what access (if any) you have to the network
stream, and then if it's not a file-like object, you'll need to wrap it in
one. I believe the main requirement for a file-like object, as far as the
Python XML reading tools are concerned, is just that is have a read() method
that supplies all the bytes of the XML to be parsed.

That assumes that you have a socket object. The question was very general,
asking about SSH and other network streams. I don't know what SSH libs are
available for Python and what their APIs are, so I make no assumptions as to
how they expose their decrypted incoming streams. General question gets a
general answer. :)

Subject: [XML-SIG] PyXML parser problem
Message-ID: <20040304221600.40d2c2c9.bob@robisonranch.net>

I'm trying to get some existing code running with py2exe 0.5.0 and am having some problems.

I've narrowed things down to a simple test file:

#!/usr/bin/env python
from xml.dom.ext.reader import Sax2
xr=Sax2.Reader()
print "Success"

If I run this with 'python test.py' then I get an Attribute error returned from saxexts.py:

  return drv_module.create_parser()
Attribute Error: 'module' object has no attribute 'create_parser'

If I run python interactively, and then type in the commands above from the prompt, it works fine.   I don't understand what the issues are, but obviously there is something in the environment that is different.

Putting in a few prints in the saxexts.py library, it appears that the parser that is trying to be created is pyexpat -- which fails.  When it works it apparently tries 'xml.sax.drivers2.drv_pyexpat' which seems to work.  I hard-coded to try the specific name mentioned above and then it works running the test.py file.  However, when I try to use py2exe I get a similar problem: The make_parser routine returns:
xml.sax._exceptions.SAXReaderNotAvailable: No parsers found.

Can someone offer some clues about the differences in these environments, and how to possible force the right thing?

I'm using py2exe 0.5.0, Python 2.3.3, and PyXML 0.8.3 on Windows 2000.  The original program (and all of my normal work) is done on Linux, where I've been using Python 2.2.  I haven't tried upgrading the Linux to 2.3 yet.  I would have tried Python 2.2 on windows, but py2exe was wanting the later python.

Help!

ElementTree is pure Python, and uses only mechanisms that have been
in Python since the early days.  If an application using it crashes, the
cause of the crash is probably somewhere else.  In order, I'd suspect
the following:

    a C extension you've written yourself (look for reference count errors)
    the database interface
    the Python bindings for the database interface
    the database
    that other C extension you've written yourself
    the Python bindings for the XML parser or the parser itself
    hardware problems (bad RAM)
    a computer virus
    that newly introduced odd corner of Python that your code is using
    a bad day
    several bad days in a row
    the parts of the Python core used by element trees

A slightly odd question here, I'd think.

To 'pass stdout' you simply use the shell 'piping'

  myprocess_whatever | python mypython

If you have created a tunnel with SSH then that will have established
a local port to connect to. You simply let your Python script connect
to that port. It does not have to know that that is SSH tunnel anyway.

Not sure about the 'standard python xml reader', but pretty much
everyone allows to parse from a stream, file or a string.

Reading the docs helps.

For me the following worked with py2exe 0.4.2, Python 2.3.3, PyXML 0.8.3 on 
Windows XP:

setup.py py2exe --includes xml.sax.drivers2.drv_pyexpat --packages encodings --
force-imports encodings

Using "-p xml" or "-p _xmlplus" instead of "--includes xml.sax.drivers2.drv_pyexpat" 
didn't work for me, but are suggested elsewhere.

Also note that py2exe 0.4.2 and 0.5.0 differ a bit, but probably only in other 
respects.

Chris,

  Thanks!  That did the trick.  py2exe 0.5.0 didn't like the --force-imports argument, so I had to leave that out, but using the --includes seems to have solved the problem.  I appreciate the help!

Summary: HTMLDocument and HTMLElement upper case attributes sometimes

Initial Comment:
xml.dom.html.HTMLDocument overrides createAttribute of
xml.dom.Document to create an attribute with an
uppercase version of the attribute name passed in. 
xml.dom.html.HTMLElement then overrides getAttribute,
getAttributeNode, hasAttribute, removeAttribute and
setAttribute of xml.dom.Element to look for attributes
with an uppercase name.  So far so good (bug: 555303
not-with-standing).

Unfortunately xml.dom.ext.reader.Sgmlop calls
setAttributeNS (which eventually calls through to
createAttributeNS in xml.dom.Document) to create
attribute nodes on the HTMLElements.  This neatly
bypasses the uppercasing done in HTMLDocument and
HTMLElement and means that none of the neat
htmlanchorelement.href attribute references work.  Shame :(

Seems like the simple fix is to add createAttributeNS
to HTMLDocument and/or setAttributeNS to HTMLElement
and have these methods pass through to the base class
methods with uppercased names instead. Although it
seems like a more thorough fix would invovle making
sure that all the (get|set)Attribute(.*) methods of the
xml.dom.html objects are made auto-upper-case-magic.

hi
if you need speed, check out libxslt
(www.xmlsoft.org).
it is written in C and comes with Python bindings
included. 
it is way faster than a pure Python processor.

if speed is not important, 4suite has a great XSLT
processer

I regret to bring this up and offend the hard workers who have written
4suite, but I noticed the same thing.

I processed a 2 Megabyte document on my 300MHZ machine. libxst took 6
seconds. xalan and saxon took about 15 seconds(counting how long it took
java to "warm up.") 4suite took 1 minute and 50 seconds.

Perhaps I am missing something? Or is the feeling that speed is not that
important, since most people process relatively smaller docuemnts, where
one wouldn't notice the speed? For example, with a 20k document, 4suite
might be faster than the java appications.

Did you try the C implementation of Xalan? It should have less startup
overhead. And there are Python bindings here:

Subject: [XML-SIG] Problems with "ignorable whitespace" in python's minidom
 and pulldom !
Message-ID: <405025EE.9050203@aon.at>

Hello,

I hope this is the right mailinglist for this kind of topic. If not, do not 
hestiate to ignore this posting or direct me to another mailing list.

Here is the problem:
My application is a web server centered programm that uses mod_python and xml 
has to process xml files. These xml files have most of the time ignorable white 
spaces like \n, \r \t between the different tags. The problem is that minidom 
seems to interpret these white spaces as text nodes and I cannot know in before 
how many of these "text nodes" are in between the real data nodes. This seems to 
disturb the real structure of the dom tree and child nodes are no longer child 
nodes etc. That makes it hard to write a reliable xml application since I cannot 
know how many spaces the writer/editor of the xml file has put in between the 
tags. So I tried to find a way of getting rid of these unwanted text nodes with 
this piece of code but that did not help either:


################################################################################
#
################################################################################
def cleanUpNodes( nodes ):
	"""Removes all TEXT_NODES in parameter nodes that contain only 		characters
	that are defined as whitespace in the string library"""

	for node in nodes.childNodes:
		if node.nodeType == Node.TEXT_NODE:
			node.data = string.strip(node.data)
	nodes.normalize()

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


I tried out also pulldom, but it interprets the white spaces as "CHARACTER" 
envents and not as "IGNORABLE_WHITSPACE" events. Another thing is that pulldom 
seems to never generates an "END_DOCUMENT" event ?!

The big question is:
Does anybody know a way around this problem ?
Am I missing something ?
How can I get rid of this unwanted white-space-text-nodes ?

Here is an example that shows what the same code inteprets as child node when 
processing the same xml file without and with white spaces in between the tags:


<############### XML File with white spaces #################>

That's correct. That's what the DOM specification says should be done by 
default.

In DOM Level 3 Load/Save there is a DOMConfiguration parameter 
'element-content-whitespace' which can be used to filter out ignorable 
whitespace at parse-time. However minidom does not yet support DOM 3 LS.

(Plug detour:) pxdom does support this, but like minidom it does not 
(yet) read external entities such as the DTD external subset, so unless 
you're putting <!ELEMENT> declarations in the internal subset of the 
<!DOCTYPE> they won't be able to tell which elements contain 'element 
content'; in this case whitespace is not 'ignorable' by design.

A workaround - and the only way to do it if you're not using DTDs anyway 
- is to tell pxdom to assume all undefined elements contain 'element 
content'. Hence the following example would give you a document free of 
whitespace nodes:

   import pxdom
   doc= pxdom.parse('filename.xml', {
     'element-content-whitespace': False,
     'pxdom-assume-element-content': True
   })

(End plug detour.)

DOM specifies that the document text nodes will be in 'normal' form 
after parsing, so you can be sure it'll be 0 or 1, no more. (Unless 
you're using a *really* old minidom where this may not hold true.)

That should work, you'd just need to make it recursive so it does the 
whole subtree not just the immediate children. Here's another version:

   def removeWhitespaceNodes(parent):
     for child in list(parent.childNodes):
       if child.nodeType==node.TEXT_NODE and node.data.strip()=='':
         parent.removeChild(child)
       else:
         removeWhitespaceNodes(child)

Hello Andrew,

thanks for your answer. After doing some research on the internet I have found 
out that you are the author of the python pxdom module. How is pxdom compared to 
the standard dom and minidom implementation shipped with python itself ? Can it 
already be used in production environments ? How "fast" is it when parsing 
larger documents ? I have read that the next version 1.1 will also support 
external resource resolution & loading. Does that mean that it can also load 
external xml files linked to the actual xml document by a kind of url ?

regards,

Arno Wilhelm

Yes. Hello!

> with python itself?

I haven't devised any sort of proper DOM benchmark, but timing (a) the 
W3C DOM test suite and (b) the PXTL test suite showed pxdom to be 
similar in speed to PyXML's 4DOM, considerably slower than minidom.

It depends on what kind of operation is being done, of course. YMMV.

> Can it already be used in production environments ?

For the DOM Level 1 and 2 features, yes; these have been pretty static 
for some time. DOM Level 3 was a moving target up until recently so the 
implementation is not so mature, but 1.0 [final] seems fairly stable. 
There is still the chance that the specification for DOM Level 3 might 
change again before it hits final Recommendation, but hopefully not in 
any significant manner.

> How "fast" is it when parsing larger documents ?

Really slow. It's a pure-Python parser with minimal optimisation, quite 
apart from DOM memory footprint issues. pxdom aims for correctness and 
ease of embedding in other projects (without having to worry about 
whether/what-versions-of other XML packages are installed); for speed, 
by design, it's very poor.

 > Does that mean that [1.1] can also load external xml files linked

Kind of: the URI is used in an entity declaration, for example:

   <!ENTITY fish SYSTEM "../entities/fish.ent">
     ...
   &fish;

Most notably, the DTD external subset ("xhtml1-strict.dtd" etc.) is 
loaded like this in the <!DOCTYPE> declaration.

The feature is only of use if you're dealing with DTD-reliant 
(non-standalone) documents. If you're looking for a general-purpose XML 
inclusion scheme, check out XInclude.

cheers,

HI, I'm trying to install PyXML and also Imaging just to run Skencil (vetorial graphics), but it is being hard. 
I read in the Imaging's readme file that I needed the Python with support for development. So, I downloaded the source code of python 
2.33 and installed it, as recommended in the readme file. 
However, and I type "python setup.py build" to install PyXML, the following msg appears: 
running build 
running build_py 
running build_ext 
error: invalid Python installatinon: unable to open /usr/lib/python2.3/config/Makefile (No Such file or directory) 
 
Well, I'll wait for help because I'm having a lot of trouble just to install a simple program that has a lot of dependencies. 
Bye 
Rafael

Subject: [XML-SIG] Locator and unknown line and column numbers
Message-ID: <40584CB7.6080104@livinglogic.de>

Hello XML-SIG!

How should a parser report unknown line and column numbers?

I have a SAX parser for sgmlop that handles line numbers
simply by splitting the input into lines and feeding
them to the parser. This takes care of the line numbers, but
feeding character by character to the parser to get column
numbers would probably be to slow, so the column number is
unknown.

I've implemented getColumnNumber() as:
    def getColumnNumber(self):
       return None

as None is IMHO the best representation of "unknown".
Unfortunately this doesn't work with SAXParseException,
because SAXParseException.__str__() uses "%d" for
formatting the column number.

So should I use some nonsense integer value for this
or should SAXParseException.__str__() be changed to
be able to handle None?

Bye,
    Walter D?rwald

I'd certainly prefer to see the later; it makes more sense for Python.

Subject: [XML-SIG] Python Web Service Client Question
Message-ID: <6.0.3.0.0.20040324160335.0223cdd8@localhost>

Good afternoon,

         I'm trying to write a simple web service client in Python.  The 
web service I'm trying to access is simple.  It takes an integer and 
returns a String.  For some reason, when Python serializes the request, I 
get this snippet (sanitized a bit):

....snip....
<SOAP-ENV:Body>
<methodName>
<empno>
<empno xsi:type="xsd:integer">123</empno>
</empno>
</methodName>
</SOAP-ENV:Body>
....snip....

     The web service complains that it expects a simple type, and I can 
understand why, given what I pasted above.

     I can get Python to name the first <empno> whatever I want it to be 
named, but I can't get Python to remove it.  So, I guess there are two 
approaches:

1) Figure out how to get Python to remove the outer <empno>
2) Name the outer <empno> something that the web service won't complain 
about (i.e., <doNotParseMe>)

     I can't figure out how to do either of the two approaches.  Perhaps 
there is also another approach (this is only my second day coding in 
Python, though I'm already thoroughly amazed by the language).

         Here is the Python web service client code:

from ZSI.client import Binding
from ZSI import TC

log_file = open('soaplog.txt', 'w+')
u = '/WebService.jws'
n = 'http://www.openuri.org/'
b = Binding(url=u, ns=n, host='localhost', port=7001, tracefile=log_file)

class MyInt:
     def __init__(self, Empno):
         self.empno=Empno
MyInt.typecode=TC.Struct(MyInt, [TC.Integer('empno')], 'empno')

empnum=MyInt(123)

result=b.methodName(empnum)[0]
print result

Thanks,

Josh

Hi everyone,

I'm going to be teaching a course on building Web pages with Web standards
and I thought it would be fun to show a little demo of a python script that
could extract information from an XHTML document. I found Simon Willison's
description of using Xpath and Python, but I haven't had any luck getting an
Xpath expression that works.

I've got a Web page at

http://www.hopkins.k12.mn.us/Pages/district/special/pq/timelytopics.html

that lists a bunch of upcoming tech classes in our school district. I'd like
to extract the coursetitles and dates.

Would anyone be willing to have a quick look at the source for that page and
suggest a way to address the <h3 class="coursetitle"> and <p class="date">
information?

Perhaps

from xml.dom.ext.reader import PyExpat
from xml.path import Evaluate
from xml.dom.ext import PrettyPrint

path0 = '//h3[@class="coursetitle"]'

reader = PyExpat.Reader()
dom = reader.fromUri('http://www.hopkins.k12.mn.us/Pages/district/special/pq/timelytopics.html')

myElements = Evaluate(path0, dom.documentElement)
for element in myElements:
    PrettyPrint(element)

The question is - are you asking for help with getting Python to apply 
an xpath expression, or are you asking for help in writing the correct 
xpath expressions?

Hey Tom,

I understand how to use the Xpath expression once it's created. I'm just
having trouble finding the right expression. I wrote a little script that
used Xpath on an RSS feed a year or so ago, but this XHTML file has me
puzzled.

It is simple in xslt.  It would be an expression like this -

//html:h3[@class='coursetitle']

The problem is that you are using a default namespace, and there is no 
standard way to tell XPath to use it.  There is no prefix bound to the 
xhtml namespace.  In xslt, you can bind a prefix in the stylesheet, and 
that is where the "html:" would come from.

Some xpath processors let you bind a namespace, but I am not sure about 
the PyXML one.

One approach would be to run the source through an xslt stylesheet that 
is an identity transform except that it adds an explicit namespace 
prefix.  Then an xpath expression like the one above would work.

Cheers,

Tom P

Yes, it's quite possible.

To expand on Luis's example, I added the 'html' prefix to the XPath
expression, and created an explicit XPath context with the appropriate
binding, rather than letting a simple, default context be created by
Evaluate() (don't worry if you don't know what I mean by that) (and
I haven't tested this):

from xml.dom.ext.reader import PyExpat
from xml.path import Evaluate
from xml.xpath.Context import Context
from xml.dom.ext import PrettyPrint

path0 = '//html:h3[@class="coursetitle"]'

reader = PyExpat.Reader()
dom = reader.fromUri('http://www.hopkins.k12.mn.us/Pages/district/special/pq/timelytopics.html')

ctx = Context(dom.documentElement, processorNss={'html': 'http://www.w3.org/1999/xhtml'})
myElements = Evaluate(path0, context=ctx)
for element in myElements:
    PrettyPrint(element)


If you need the empty namespace (no namespace), use xml.dom.EMPTY_NAMESPACE.
If you need an empty prefix to assign the default namespace, use
xml.dom.EMPTY_PREFIX. Note however that changing the default namespace does
not affect how QNames are interpreted in XPath expressions.

You can also create variable bindings in the same way, with a dictionary named
varBindings. Make the keys be tuples consisting of (namespace, local-name) of
each variable.

The API in 4Suite is about the same, but with Ft.Xml.XPath instead of
xml.xpath, and you must supply a Domlette document, not a minidom document, in
the context.

I've got a ton to learn about XML processing, but I was able to piece the
following together using libxml2 and Simon Willison's information at
http://simon.incutio.com/archive/2003/10/21/xpathRocks

#!/usr/bin/python

import libxml2
import urllib2

url = 
'http://www.hopkins.k12.mn.us/Pages/district/special/pq/timelytopics.html'

dom = libxml2.parseDoc(urllib2.urlopen(url).read())
ctxt = dom.xpathNewContext()
ctxt.xpathRegisterNs('xhtml', 'http://www.w3.org/1999/xhtml')

titles = [t.content for t in
ctxt.xpathEval('//xhtml:h3[@class="coursetitle"]')]
newtitles = []
for title in titles:
    newtitles.append(' '.join([word.strip() for word in title.split()]))
newtitles.sort()
for title in newtitles:
    print title

I couldn't find any way to remove extraneous whitespace from the tag
contents without all the splitting, stripping, and joining.

I just did this a couple days ago. Here's what I did:

1. Visit http://homepages.cwi.nl/~jack/macpython/download.html and download
the MacPython 2.3 for Panther addons installer.
(http://ftp.cwi.nl/jack/python/mac/MacPython-Panther-2.3-2.dmg)

2. Once installed, you'll find a MacPython-2.3 folder in your Applications
folder.

3. Run the PackageManager

4. At this point, PackageManager will probably give you an error that it
couldn't download an information.

5. Now visit http://www.python.org/packman/ to try downloading a different
database. I found that the experimental version for 10.3 worked for me.
(http://www.python.org/packman/version-0.3/exp-darwin-7.0.0-Power_Macintosh.
plist)

6. Use the URL of that plist file in the "Open URL" option in the File menu
of the PackageManager.

7. Once PackageManager is able to connect to that database, you'll be able
to choose to install libxml2 from the list of available packages.

8. Q.E.D.

Hope this helps.

Could you be a little more explicit? 

I installed libxslt on my girlfriend's Mac OS X. It was just a matter of
downloading the package and doing the typpical

python setup.py build
python setup.py install

Are you having specific problems?

Anyone else think this looks fishy?  The originating address is outright 
wrong - it claims to be from mail.python.org ([12.155.117.29], which 
would not make sense and is the wrong IP address for python.org anyway, 
and the intent seems to be to get you to click on the links.  That's 
suspicious right there.

The constructor for the Text class has never been part of the documented API.  
The __init__(), in particular, was removed to support faster creation of an 
entire tree (which was very successful).

The Document object has a factory method, createTextNode(), that takes the 
text for the node as the only argument.  This is the only documented and 
supported way to construct new text nodes.  Other factory methods are used 
for other node types.

Hi Fred,

So does that mean that the Text class can not be subclassed?  Looks like Text's parent class
CharacterData has an __init__, i thought calling init on Text would have been forwarded to its
parent?
Here's my code:

class TextNode(BaseNode, xml.dom.minidom.Text):
	def __init__(self, data):
		BaseNode.__init__(self)
		xml.dom.minidom.Text.__init__(self, data)

You certainly can subclass Text, but CharacterData does not have an __init__() 
either (else Text would inherit it).  Your subclass will need to either 
initialize the .data and .ownerDocument attributes in the __init__(), or 
you'll need to initalize them after construction.

I've added a comment to the source since this question comes up so frequently.

Subject: [XML-SIG] ANN: exportLiteral extension to generateDS.py
Message-ID: <20040330113236.A85233@cutter.rexx.com>


I've implemented an extension to generateDS.py.

generateDS.py generates Python classes that represent the elements
in an XML document, given an Xschema definition of the XML
document type.

The new extension will export a Python literal representation of
the XML document.


What It Does
============

When generateDS.py generates the Python source code for your
classes, this new feature also generates an "exportLiteral" method
in each class. If you call this method on the root (top-most)
object, it will write out a literal representation of your class
instances as Python code.

generateDS.py also generates a function at top level
(parseLiteral) that parses an XML document and calls the
"exportLiteral" method on the root object to write the data
structure (instances of your generated classes) as a Python module
that you can import to (re-)create instances of the classes that
represent your XML document.


Why You Might Care
==================

This feature means that the classes that you generate from an XML
schema support the interchangeability of XML and Python literals.
This means that, given classes generated by generateDS.py for your
XML document type, you can perform the following transformations:

- Translate an XML document into a Python module containing a
  literal definition of the contents of the XML document.

- Translate the literal definition of a Python data structure into
  an XML instance document.

This capability enables you to:

- Work with an XML (text) document, then exchange it for a Python
  text representation of the content of that document.

- Work with a Python literal text representation of your XML
  document, then exchange that for an XML document that represents
  the same content.

- "Freeze" your XML document as a Python module that you can
  import. The module can be edited with your text editor, so
  perhaps it would be better to say that it is frozen, but not too
  hard. The classes that you generate with generateDS.py can be
  used to:

  1. Read in an XML document.

  2. (Optionally) modify the Python instances that represent that
     XML document.

  3. Write the instances out as a Python module that you can later
     import.


Where to Find It
================

You can find generateDS.py at:

    http://www.rexx.com/~dkuhlman/generateDS.html.
