Hmmm. I started my system with (RedHat 6.2):

$ rpm -q python PyXML
python-1.5.2-13
PyXML-0.6.5-1

Then bootstrapped with ARK to:

$ ls python*.xml PyXML*.xml
PyXML--0.6.5.xml  python--2.1.xml

Here's what I get:

$ python
Python 2.1 (#3, May 27 2001, 14:54:04)
>>> import xml.dom.core
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
ImportError: No module named core
>>> 

Interesting... Took a look at the code and I see:

        try:
            # this ought to be Python 2.0 with PyXML 0.6.1 or
            # thereabouts.
            import xml.dom.ext.reader.Sax
            [...]
        except ImportError:
            # this is probably something like Python 1.5.2/1.6
            # with PyXML 0.5.5.1.  Or *something*.
            import xml.dom.core
            [...]

If I try:

$ python
Python 2.1 (#3, May 27 2001, 14:54:04)
>>> import xml.dom.ext.reader.Sax
>>> 

No problem. Similarly:

$ /usr/bin/python
Python 1.5.2 (#1, Feb  1 2000, 16:32:16)
>>> import xml.dom.ext.reader.Sax
>>> 

So I can only guess that something is weird with your installation where 
it looks like an old PyXML, even though it's a new one. Can you try the 
above and report back what you get. Also:

>>> import xml
>>> xml.version_info
(0, 6, 5)
>>> 

and of course, which version of Python you're using.

I'm not sure it's the "latest and greatest" that's the problem, I think 
it's all the ones in between. Unfortunately, Python and PyXML have been 
through some revisions and we've not tried all of them together.

I understand your frustrations and we do appreciate your criticism. I 
think one of the problems at the moment is that the only people using 
Arusha are Arusha-users ;-) It's a FAQ-chicken-and-egg thing.

I'm sure this is some curious incompatibility that we can iron out.
