RegEx help

Hello all, Im a bit rusty with regular expressions and I know this is an easy one so im kicking myself for not having it that much more. Im simply trying to ensure that a given string has between 6 and 12 characters and contains at least 1 numeric character.

I say break it up into two different test: <cfif   REFind( "[\w]{6,12}", strText ) AND   REFind( "[0-9]+", strText )>    </cfif> It keeps it much more simple and easy to read than a bigger, more complex RegEx .....................

You can also still do it in one cfset with Ben's 2 separate expressions... <cfset var = "abcdefg1" /> <cfset newvar = refindnocase("[\w]{6,12}", var) AND refind("[0-9]+", var) /> .:.:.:.:.:.:.:.:.:.:.:.

Can't resist the challenge. :-) "^(?=.*\d).{6,12}$" I'm not sure if this will actually work in CF. Patrick ----- Excess quoted text cut - see Original Post for more -----

That looks VERY similar to one I found and tried for this thread :-) It didn?t work either. It was the same problem, '111111' validates but he asked for letters and at least 1 number. I took that as meaning it has to have at least 1 letter and at least 1 number. .:.:.:.:.:.:.:.:.:.:.:.

You could try this...   \b[(\d+|\w+)]{6,12}\b Hello all, Im a bit rusty with regular expressions and I know this is an easy one so im kicking myself for not having it that much more. Im simply trying to ensure that a given string has between 6 and 12 characters and contains at least 1 numeric character. Any help would be greatly appreciated! -chris

Forget my attempt, Patrick's works perfectly. You could try this...   \b[(\d+|\w+)]{6,12}\b

No it doesn't. Neither does yours. Patrick's was closer though. The only thing I could find that it failed on was an all numeric string 6 to 12 characters long. Yours failed for that as well as a string of all letters 6 to 12 characters long. Where's Ben Doom? lol .:.:.:.:.:.:.:.:.:.:.:. Bobby Hartsfield http://acoderslife.com Forget my attempt, Patrick's works perfectly. You could try this...   \b[(\d+|\w+)]{6,12}\b

What engine are you testing with?  Patrick's pattern validates against all numeric, all alpha, and mixed against Perl 5, JDK 1.4 and JDK 1.5 implmenetations. No it doesn't. Neither does yours. Patrick's was closer though. The only thing I could find that it failed on was an all numeric string 6 to 12 characters long. Yours failed for that as well as a string of all letters 6 to 12 characters long. Where's Ben Doom? lol

All numeric and all alpha should fail according to the requirements of th original post .:.:.:.:.:.:.:.:.:.:.:.

> What engine are you testing with?  Patrick's pattern validates against > all numeric, all alpha, and mixed against Perl 5, JDK 1.4 and JDK 1.5 > implmenetations. He's saying "all numeric" isn't valid; there must be at least one letter. If you want to require at least one number *and at least one letter* this should work. /^(?=.*\d)(?=.*[A-Za-z]).{6,12}$/ Patrick -- Patrick McElhaney 704.560.9117

'11111a111111' fails 'aaaaa1aaaaaa' fails '11111a' fails 'aaaaa1' fails Actually... I guess everything I feed that one fails. Just go with Bens original solution. It made it MUCH easier. .:.:.:.:.:.:.:.:.:.:.:.

Sorry, can't get this outta my head now.  Too interesting a challenge. I believe this one will do it.   ^(?=.*[A-Za-z])(?=.*[0-9])(?!.*[^A-Za-z0-9])(?!.*\s).{6,12}$ LOL, as was said originally, easier to break it up into two expressions than worry about creating a monstrous pattern (as shown above).

Niiiiiiiice :D Yeah, I know what you mean. I have gone back to this like three times and couldn't figure it out. I have never used chained look aheads. That's a nice little trick (or rather usage of the language). Freakin' sweet. .....................

NOW you got it :-) good job. I tried a couple times myself. Then gave up... then I got annoyed and tried some more.... wash -> rinse -> repeat.... lol .:.:.:.:.:.:.:.:.:.:.:.

>         ^(?=.*[A-Za-z])(?=.*[0-9])(?!.*[^A-Za-z0-9])(?!.*\s).{6,12}$ > Hmm... I don't think this part is necessary: "(?!.*[^A-Za-z0-9])(?!.*\s)"  No one said anything about non-alphanumeric characters being disallowed, did they? If that's what you're going for we can simplify a bit. ^(?=.*[A-Za-z])(?=.*[0-9])[A-Za-z0-9]{6,12}$ Patrick -- Patrick McElhaney 704.560.9117
