I've never done this, but I found a recipe on the ActiveState website
that looks like it would be helpful:

http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/159100

I think you could modify it to make it work.

You could probably also use a combination of the csv module and the
pyxml module (links below).

http://pyxml.sourceforge.net/topics/
http://www.rexx.com/~dkuhlman/pyxmlfaq.html

I also found a Python XML book: http://www.oreilly.com/catalog/pythonxml/chapter/ch01.html

I hope that helps. I've started my own adventure into XML with XRC and
wxPython.
