Do you need to use regular expression on an occasional basis, but don’t use them enough to become a regular expressions expert. If you answered “yes”, then I have a great solution for you. RegEx Builder is a small utility to help you build regular expressions. Especially useful for those, like me, who don’t use regular expressions everyday, and therefore, don’t always remember all the details. RegEx Builder evaluates your expression as you type so you can see if it is going to match your target text in real-time. No more edit-compile-test loops.
