How do I split a string using a regex?

问题

I’d like to split a string using a regular expression. I have browsed the various regex modules on Hackage, but I can’t make any sense of them. (I have noticed Data.List.Split, but it doesn’t seem to offer what I need, either.)

This may help you:

ghci > import Text.Regex.Posix
ghci > getAllTextMatches ("good food" =~ ".ood" :: AllTextMatches [] String)
["good","food"]

Real world haskell book has a nice chapter on it.
