I have positive experiences with regex-compat, regex-posix packages, you can get these from hackage. When your expression becomes more complicated it may be worth to use parsers instead: faster processing, refactoring parsers is also easier.

In Haskell virtually everyone uses parser combinator libraries like parsec, megaparsec, or attoparsec depending on their needs.
Many people ask this question and are then disappointed when they can't find a definitively standard regex library to use. That's because they are barely needed.
That's not to say that there are no such libraries There are. But I personally couldn't suggest any as I have not been compelled to use one in many years.

Hi,
Which package is the most popular and/or easy to used for dealing with regular expressions? My regex is quite simple and I just need to get 2 or 3 capture groups from the result.
Many thanks
