I use flex & lex a lot for stripping stuff from e-mail attachments in scritps. I wondered if there are moden versions and variants of the lex programs that have the perl REGEX extensions.

I know the boost libs support perl style but this is not quite what I am looking for.

I found Pro Perl Parsing to be a good book on the topic, covers grammars and lexing themselves as well as different cpan modules.
