"XMLtreeview" under "Cool Contribs" in the demo that is included 
with wxPython shows how to ~read~ an XML doc into a tree 
control. I can't evaluate this in comparison with what Cameron Laird 
has already posted in response to your query; however, 
XMLtreeview is a particularly easy-to-read example.
