It looks like you're using a bunch of negative look-ahead assertions to make sure your strings don't start with certain patterns. There are ways to combine them, but you'll have something that's a bit hairy and inefficient. I would rethink what you're parsing a bit, perhaps focusing on positive rather than negative matches for the data you want.

I recall there being a Regexp merging module on CPAN, but I've never used it and cannot find it at the moment. It might be helpful for you.

Check the regular expressions manpage here. I also recommend reading the Mastering Regular Expressions book (O'Reilly information is here and author's web site here) for a tutorial about optimizing regular expressions.
