Yes, thanks Martin this saves us a lot of time.  Question, will it
handle "mod mod mod" or "* * *"?  These needs to translate to the token
wildcard name, operator, wildcard name.  I ask 'cause this caused us
many headaches with 4XPath.  We had to do it with flex state.

This wouldn't be that difficult.  A simple interface to get a list of
tokens(and the matched string) from the scanner would suffice.  We will
need some logic to turn this list into YY unions for Bison, but that is
pretty simple as well.
