[Zope] More XML Doc questions (and ZCatalog)

[Jason Jones]

Is it possible to catalog individual XMLDocument elements with ZCatalog? For
instance, if my XMLDocument has something like "<abstract>some
text</abstract>" can I catalog only that individual element, plus any
sub-elements (by setting up an "abstract" text index in my ZCatalog)?

What I would eventually like to do is build a system for storing scientific
papers and I want to use XML as the archive format, but I'd like the ability
to run searches over arbitrary sections of the document collection. From the
readme file, it seems like XMLDocument would parse the file into a
collection of objects that could be cataloged, but in practice it doesn't
seem to work this way. I can catalog the entire document or add stuff to a
property sheet and catalog that, but I can't catalog pieces of the xml file.

Is this possible?

Also, I thought I'd repost my earlier question as it's also along these
lines -------
