I haven't used gcc-xml but it would seem to me the right tool for the job.

As an alternative you could use SWIG, and output the results to xml (use 
the -xml or -xmlout options). Then parse that XML with rexml or libxml.

C++ is a pretty complex language to parse, but SWIG understands most of 
it - certainly enough to locate methods and functions.
