Take a look at Parse::RecDescent*. In general, it doesn't matter if you want to work with a small piece of a language or the whole language, you still need to implement a parser for the whole language. You can get an eighty or ninety percent solution without a full parser, but there will always be problems. * http://search.cpan.org/dist/Parse-RecDescent/lib/Parse/RecDescent.pm -- Chas.
