Xindice, eXist, or something else?

[Peter Michelson]

Has anyone had success in using python with a native XML database such as
Xindice or eXist?  I am interested in any experiences or recommendations in
this regard.  In particular, I would like to store, query, modify, and
retrieve semi-structured data, in which the fields themselves would be
highly dynamic.

Would appreciate any relevant comments on this.  Thanks, Peter
