.NET Forum / Languages / C# / August 2006RegEx question?
I am looking for a regular expression that will match a string that contains the word "clamp" but will not match if the string also contains the word "arch". So, No Match: "Arch Clamp" "ArchClamp" "archclamp" "yada archie clamp" Match: "Clamp" "sring clamp" "deck clamp" Is there an easy way to do this in a single expression? Thanks in advance.

Check out ultrapico.com GPG > Maybe something like this > > (?i)(?-imsnx)^((?!(.*arch.*)).*(clamp))$ Thanks! Very very close. I had to remove the trailing $ as "clamps" is also a match. > There is a fantastic tool called Expresso that I use to develop and > analyse regular expressions - it is even free. Check out ultrapico.com Tool looks great! I haven't given it a try as of yet, but I did open the tutorial. I think there is a risk that my Regex skills might actually decrease after this ;-) SignatureThomas T. Veldhouse Key Fingerprint: 2DB9 813F F510 82C2 E1AE 34D0 D69D 1EDC D5EC AED1 No problem! Expresso is extremely handy plus is will generate c# code for you based on the regex that you develop. Just the ability to run test matches and build expressions makes this app a must in my toolbox.
