Regular Expressions can really be a pain in the ass – so any help is normally welcome. Today I will present a Cheat Sheet by AddedBytes.com which is really helpful when dealing with regular expressions. I'm proud to announce this sheet, because they also have a variety of other great cheat sheets available for download on their site.
The newest one concentrates on regular expressions – simple yet colorful as ususal.
In the end I would like to recommend another useful Plugin for Firefox this time. The Regular Expression Tester can also be of great help.
