RegEx find/replace and CFE

I've never heavily used RegEx find/replaces (which up to this point makes me wonder how?) so I didn't properly take in Adam Howitt's post about Simplifying Form Validation with Eclipse Backreferences first time round. If i did i could of saved myself some time last week...thats another story. Not only does it show the power of CFE (as well as other editors) but is shows the power of RegEx find and replace.
