I was reading ICU documentation and came across this fine advice:

For common tasks like this there are libraries of freely available regular expressions that have been well debugged. It's worth making a quick search before writing a new expression.

To which libraries of well-debugged regular expressions do you commonly refer?

I'm not much taken with http://regexlib.com where the expressions don't seem all that well debugged. It appears to have no QA process besides user comments and ratings.
