[GCC-XML]Some questions

No.  See this web page for an explanation:

This answer is subsumed by the fact that only declarations are dumped.
Every declaration has its exact location dumped, but function definitions
(bodies) are not dumped.

Yes, that is the ultimate goal.  Having an XML representation of all of
C++ will open the language to tools in many other languages.  For now, you
might want to look at OpenC++ for a more complete parser.
