Regular Expression Tools

I'm still at the point where I can use stuff like ^\d{3}[-| ]?\d{2}[-| ]?\d{4}$ and not fully understand the pieces. So i'm always looking for decent RegEx tools. Eric Gunnerson had a good post about suing RegEx to validate a SSN

But first, a word about tools. It's a lot easier to use a tool to do this sort of thing than it is to write code to do it. So, I suggest one of the following

• The Regulator. No fair to use the library if you choose this tool. Uses a bit of code I wrote to analyze regex for you.


• Regular Expression Workbench (classic) . I wrote this


• Regular Expression Workbench (updated). Version with a different UI on it.
