The Regular Expression Library lists a lot of common used expressions. You’ll also find a handy expression-tester in there.

Regular Expressions are used for searching and parsing of text and is a powerful feature, implemented in most programming and scripting languages.

I tend to get dizzy over this stuff, so next time I need to do a regular expression that somehow can be generalized into a common task, this site would be my first shot.

Example: This regular expression matches a six character “password” that has to consist of numbers and letters with at least one letter in it:

     ^(?![0-9]{6})[0-9a-zA-Z]{6}$

I know — it’s not easy to read. See A Tao of Regular Expressions for an introduction. And there’s also a RegExp weblog.
