[Zope] Indexing and Searching through XML files

[FNk]

Hi,

I got lots of XML-files(about 100.000) in a directory tree on my file
system. I want to publish those files using Zope/Plone.

I need to be able to index them in their native format without having to
upload them in the ZODB, let users search their contents through zope, and
have the result displayed.

Is it possible? Did anybody ever do this? Any suggestions? 

I'm running zope-2.6.2 and Plone-1.1.

Thanks,

Fab.
