Sorry for not beign clear, but I don't manage the technical vocabulary yet
;-). I mean the SAXHandler struct.

I fixed this, and it's working great. James's docs and LibGlade code were
very useful in this sense. I put all the code in one handler
and I use the same to read worksheets, plots, and projects. You also have
the option to save all separate.
Now I have more doubts:
1) Can I find some documentation abour XML string handling --the
functions XMLStr*? Most of them look obvious, but anyways...
2) How do I do to parse special characters like '<' '>' in a string when
I read a content using characterSAXfunc?. I understand that they are
represented by expressions like 'lt' and 'gt' (just viewing gnumeric
files). Where can I read more to understand how to handle this?
3) Where can I read about using SAX + compression?
BTW, you migh already noted that I'm completely new to libXML and XML
itself.
Thanks a lot for your help,
