Thanks for the investigating, Jacob. So the JDK uses Perl which is why my lookbehind worked in my class, and then CF uses a "proprietary" version of Perl's implementation. Something just doesn't feel right about all that... just not sure what.
Well, no matter. You're right that tinkering with how you structure your pattern, you can mimic the [negative/positive] lookbehind function. -----Original Message----- From: Munson, Jacob [mailto:[EMAIL PROTECTED] Sent: Friday, January 06, 2006 6:04 PM To: CF-Talk Subject: RE: Regex ex question. How to match NOT this string. I just looked in my "Advanced Macromedia ColdFusion MX 7 Application Development" book (what a title! ;)), written by Ben Forta and a bunch of other folks, and this paragraph is very on topic: "...these additions make ColdFusion's RegEx support much more powerful, and much closer to the way regular expressions work in Perl, which for many people is the de facto standard for how regular expressions should behave". The additions they are talking about are things like look ahead, word boundaries, escape sequences, etc. Also, this sentence answers our previous question "ColdFusion does not support (Perl's) lookbehind processing..." Also, it looks like Java uses Perl's syntax as well: http://tinyurl.com/ay8kc ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Message: http://www.houseoffusion.com/lists.cfm/link=i:4:228693 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54
