That's perfectly understandable if you were using the
Tcl implementation of the parser. However, TclXML already
has a wrapper for Expat - did you try that?

As I said, TclXML already has a wrapper for Expat - a very
old version heavily modified by Ajuba. It would be very
helpful to update the TclXML/expat code to use the version
that's now on SourceForge (as I recall that is the
expat-1.95.0 version that you mention).
Submit the patches on the TclXML SF site and I will
incorporate them. If you are willing to be responsible
for ongoing maintenance then I'll add you as a developer
to the project.
Cheers,
Steve Ball
