new office formats, REs and Python

[tubby]

How are Python users dealing with some of the new OASIS Open Document 
formats (Open Office) or MS Open XML formats. These formats store data 
in a file which is actual a zip archive that contains numerous files and 
folders. For example, a file saved from Open Office 2.0 named 'test.odt' 
can be unzipped into many parts... content.xml, meta.xml, settings.xml, 
etc, etc.

How can I read these files do re searching and matching on them, etc? 
content.xml may have a string I'm searching for, but how would I attach 
that back to the original 'test.odt' file?

Perl seems to have a module to handle this, does Python?
