This is somewhat old news, but I've been using it lately, and figured I'd put a little reminder out here. Whenever you are trying to create a regular expression in ColdFusion and are having trouble with it, or if you're trying to use an advanced feature that just doesn't work (like lookbehind), remember that there IS a solution.
Here's a hint. Remember, CF is Java! Here's how to exploit the wonders of java.lang.String:
<cfset str = "This is my string!">
#str.matches("^.+$")#, displays YES
#str.replaceAll("\W","")#, displays Thisismystring
<cfdump var="#str.split("\W")#"/>, dumps an array of words
Everything you can do with a String can be found a the Java 1.4.2 API docs. (1.4.2 and not 1.5 because CFMX 6 & 7 support does not currently extend past 1.4.2)
