Regexenator

Regexenator is a powerful yet simple regular expression tool. You can use Regexenator to create, test, and evaluate regular expressions and search text for matches of your regular expressions. The Replacement feature allows you to use your regular expression to easily find/replace text. If you need to perfect your RegEx later, you can save your work and come back later. If you need some examples, you can use the Cookbook to get started.
