If I understand you problem correctly,

here there is a small example to parse string of the type
TEST ------ END 
where ----- can be whatever you want.

http://caml.inria.fr/pub/ml-archives/caml-list/2005/07/244afe98fd8ddfb6aff6f0bcda52d9ac.en.html

read the thread further as you need to add Stream.junk strm to the
function test.

this way you can basically switch to an other parser (to parse "----" )
and get back to camlp4.

hope it helps.
