Parsed XML an ZCatalog

I'm trying to perform searches on a parsed XML file.  No luck yet. 
Users come to my portal.... fill out a form and submit the form.  My
form posts to a python script which creates an xml file (basically a
user profile).  I would like to be able to search these xml
"user-profile" files.  I created a Catalog and did the "find-objects"
thing by selecting "parsed XML."  I'm not sure how to utilize the
indexes and meta-type features.  I have tried both.  The catalog finds
the xml objects..... but I can't seem to query elements within the xml
file.  Heck, it might be better to do this in python...... I thought I
would try the catalog feature... so far I am getting nowhere... Any
gurus out there?

Tux rules!
