There must be some external library freely available, no?
I think we basically have what we need: routines for unzipping
composite files (we have this for gretl session files), and
routines for parsing XML (we're already linked to libxml2).
In fact, I think we can read ODS (and the Microsoft stuff too, if
we want to) using a slightly modified version of the existing
gnumeric_import.c. I'm not going to start on that before 1.6.6,
but once that's out the door we could start on generalizing
gnumeric_import to handle the other XML formats.
Allin.
