LinuxQuestions.org - Python XML won't work.

I am trying to get pyXML to work and am having no luck. I could tell that it was installed but not working, so I tried to install it again. This didn't do anything. Also, I am doing this on OS X.

I have made two programs by more or less copying from Python and XML (the O'Reilly book), but they don't work. And I have tried a program from http://www.rexx.com/~dkuhlman/pyxmlfaq.html, but that didn't work either. Hopefully someone will be able to figure out what is going on.

Code:

import xml.dom.pulldom

from xml.dom.pulldom import parse



xmlhandle = open("example.xml")

xmlfile = parse(xmlhandle)



print xmlfile

print xmlfile.firstChild

Gives the message:

Code:

<xml.dom.pulldom.DOMEventStream instance at 0x4ae648>

Traceback (most recent call last):

  File "xmltest.py", line 9, in ?

    print xmlfile.firstChild

AttributeError: DOMEventStream instance has no attribute 'firstChild'

This:

Code:

import xml.dom.minidom



print xml.dom.minidom.parseString("<pete>re</pete>")

print xml.dom.minidom.parse(open("example.xml"))

Gives the message:

Code:

Traceback (most recent call last):

  File "xmltest.py", line 4, in ?

    print xml.dom.minidom.parse(open("example.xml"))

  File "/System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/site-packages/_xmlplus/dom/minidom.py", line 1908, in parse

    return expatbuilder.parse(file)

  File "/System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/site-packages/_xmlplus/dom/expatbuilder.py", line 928, in parse

    result = builder.parseFile(file)

  File "/System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/site-packages/_xmlplus/dom/expatbuilder.py", line 207, in parseFile

    parser.Parse(buffer, 0)

    assert info._model is None

AssertionError

The program from http://www.rexx.com/~dkuhlman/pyxmlfaq.html, which I am just running because it's supposed to work is:

Code:

import sys

from xml.dom import minidom, Node



def showNode(node):

    if node.nodeType == Node.ELEMENT_NODE:

        print 'Element name: %s' % node.nodeName

        for (name, value) in node.attributes.items():

            print '    Attr -- Name: %s  Value: %s' % (name, value)

        if node.attributes.get('ID') is not None:

            print '    ID: %s' % node.attributes.get('ID').value



def main():

    root = minidom.parse(sys.argv[1])

    node = root.firstChild

    showNode(node)

    for child in node.childNodes:

        showNode(child)



if __name__ == '__main__':

    main()

When run with xmltest2.py example.xml gives the message:

Code:

File "xmltest2.py", line 20, in ?

    main()

  File "xmltest2.py", line 13, in main

    root = minidom.parse(sys.argv[1])

    result = builder.parseFile(fp)
