Sometimes it is easier to make a parser than to use an existing one.
In this case I might try LEX.

 You have a warped sense of fun.
 Tend to be?  Any cites?
 And how often does the (I suspect very marginal) performance benefits
of a hand-coded lexical analyzer surpass the development/testing cost of using
a well-tested lexical analyzer generated by lex or flex, both of which
are rather efficient?

I"m currently adding xpath suppport to my XML document model.
The code is here
https://github.com/MalcolmMcLean/babyxrc/blob/topic/dataimport/src/xpath.c
(Baby X resource compilier, branch topic/dataimport, file xpath.c.)
It has a hand-coded lexical analyser. Now could the code be made better by moving to lex / flex?
I'm working on the code so it is currently in flux. But github stores a list of changes.
