  I'm a bit puzzled by your question. I do not know "STL Map", I have no idea
if this may have an influence. All I can tell is:
   - the xmlChar* string obtained from libxml2 is encoded in UTF-8
     (UTF-8 encoding and ASCII encoding match for characters in the ASCII range)
   - the string may be deallocated if you free the document or if you
     free the XPath object which was returned, I assume that's the
     problem you're facing.

   otherwise no idea.
