I’ve been having a need to do a lot of regex / pattern-matching stuff lately and, in looking at different examples / forum posts from my web searches it seems people sometimes mention that perl has good modules to help in simplifying pattern matching / regex tasks, however they neglect to mention which ones are the best for this.. I have looked at CPAN for this but their site isn’t very easy to navigate as I can’t seem to search effectively by category.. any advice is appreciated.

Take a look at Regexp::Common
Also, look at YAPE::Regex::Explain and the web front end to it. Invaluable.
