Are you asking what the ^ and $ regex operators do and why they are (or should be) used? In that case check out www.regular-expressions.info
Basically it will force the match across the entire line of text (rather than match in the middle somewhere). This has nothing to do with the <t:validateRegExpr> tag specifically. Btw, off topic a bit, but I think it would have been more elegant to call the tag t:validateRegex instead. Just my 2 cents. -----Original Message----- From: Jeff Bischoff [mailto:[EMAIL PROTECTED] Sent: Thursday, 20 July 2006 11:43 PM To: MyFaces Discussion Subject: Re: t:validateRegExpr Yes, that's the documentation webpage I was speaking of... >> By the way, I noticed in the source that you wrap all regex patterns >> with: >> '^' + pattern + '$' >> >> Do you think it is worth mentioning that in the documentation webpage >> for this tag?
