Can you compound back references Ie if I find
<div>blah</div> And lets say <div> is ref1, blah is ref2 and </div> is ref 3 Can you rereplace with something like /1xyz/2 Thus replacing blah with xyz?

REReplaceNoCase(string, "<a([^(href)]*)(href="")([^""]*)("")>([^<]*)</a>", "<a href=""\3"">\5</a>", "ALL") For reference i actually use the regular expressions cf docs (http://livedocs.adobe.com/coldfusion/8/htmldocs/regexp_01.html) Steve -----Original Message----- From: cfaussie@googlegroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Dale Fraser Sent: Tuesday, 25 November 2008 5:28 PM To: cfaussie@googlegroups.com Subject: [cfaussie] Re: RegEx Banging Head Im trying to use it, I even have Ben Forta Regular Expressions in 10 minutes.

I * love * regex, and use it quite regularly, including doing all sorts of crazy find and replaces in Eclipse to essentially do code generation. Regex FTW ;) RLY!
