Need some help with this Regex...
Hi, all... Why doesn't this Regex validate the field entry 24 as a valid number? : CFIF Len(Trim(Form.Years)) and Not IsNumeric(REReplace(Len(Trim(Form.Years)), [0-9],,All)) I thought this would mean: If Form.Years has some content and if, after taking away all digits 0 thru 9, what's left is not a valid number, then...

RE: Need some help with this Regex...
For starters, you probably want to remove the Len() inside of: REReplace(Len(Trim(Form.Years)), [0-9],,All) To: REReplace(Trim(Form.Years), [0-9],,All) Plus, the NOT IsNumeric() will ALWAYS be true since you are stripping out all numbers. IsNumeric() will never be true... Somewhere, your logic is screwey... What are you trying to do (in english)? ..

RE: Need some help with this Regex...
I would trim form.years only once... This is a jQuery Ajax validation, and the form field validates onblur every time after the field is focused. cfset form.years... I don't want to actually change for the form data... I want to return it to them as they entered it. If you're using CFMX 7... Ha! You don't realize you're talking to a luddite here...

RE: Need some help with this Regex...
Hi, Ben... and thanks for the reply... Ok... I figured out the problem... my Regex is correct as is, however, a conditional statement prior to it needed to be adjusted. Here's what's going on: jQuery is submitting info via Ajax from a form field to the code below for validation. (In this case I'll use the Years form data) CFIF Not Len(Trim(Form.Years)) CFSET Years_Error_Message = Please enter the number of years. /CFIF CFIF Len(Trim(REReplace(Form.Years, [0-9],,All))) and Not IsNumeric(REReplace(Trim(Form.Years), [0-9],,All)) CFSET Years_Error_Message = Please enter a valid number for years. /CFIF Now, I've change the first condition of the second CFIF to read: CFIF Len(Trim(REReplace(Form.Years, [0-9],,All)))... That verifies that there is data besides digits, which is what I'm trying to find out. The next condition, after the and, checks to make sure that the data is not numeric after all digits are removed... (this may be redundant now...) Here's the final code (at this point...) for validating the Years field. CFIF Not Len(Trim(Form.Years)) CFSET Years_Error_Message = Please enter the number of years. /CFIF CFIF Len(Trim(REReplace(Form.Years, [0-9],,All))) and Not IsNumeric(REReplace(Trim(Form.Years), [0-9],,All)) CFSET Years_Error_Message = Please enter a valid number for years. /CFIF Rick -Original Message- From: Ben Nadel [mailto:[EMAIL PROTECTED] Sent: Thursday, March 15, 2007 3:34 PM To: CF-Talk Subject: RE: Need some help with this Regex...

Hello I have the following regex: s = rereplace(s, a[^]*href="" ])*[^]*[^]*/a,\1,all); Which should (in theory) replace a href="" here/a With page.htm But instead it just returns click here.

Re: Help with this regex
Looks like Pascal already posted a fix, but (since you asked) it looks like your problem is that you've got (^[ ]) instead of ([^ ]).

After Ben's post I noticed a space I didn't see before. It should be s = rereplace(s, a[^]+href=""> with no spaces at all in the regexp.
