Ok , I realize, my question was to simple. I will try to ask the question in a generic way...Assume, there are two rules: 1) A : character_set_a;2) B : character_set_b;How do I set up a rule for parsing a character which must be in the character_set_a but not in character_set_b? Or by other words, a rule C succeeds when the rule A succeeds but the rule B fails Thanks to all who sent the responses, but still, it is not what I am looking for......Vlastimil
