Do you mean "match 3 characters,but not 'xyz'"? yes, 3 characters,but not 'xyz'. (xya, xxx, 12z ...) "You can get whatever effect you want by using a lookahead. For example: (xyz)(?!\1) no. (3)(?!\1) ... matches 3 from input string a3bc the term (?!\1) is just a conditional term, but (?!\1)is not included in the match. The good résult would be 3b. "Nothing like you suggest exists in Perl ..." I suspected a answer like this one. I understand, but it's a pity. i think that be able to get the opposite of a reference would be sometimes a very useful feature ! (in Perl and therefore also in PCRE) but like you say, if nothing like i suggest exists in Perl ... then this is a dead end. :-) Regards, ouadji, -- Configure bugmail: http://bugs.exim.org/userprefs.cgi?tab=email -- ## List details at https://lists.exim.org/mailman/listinfo/pcre-dev
