Thank you John for your prompt reply. I tried the same example by replacing [:xdigit:] with [[:xdigit:]] in the expression However, I still do not get the desired match. Regards, Chandan John Maddock <john@johnmaddock.co.uk> wrote: Chandan Nilange wrote:
Hello,
Why does the boost regex sample program attached here, doesnot generate match for character class [:xdigit:] Do we need to enable this character class explicity? If yes, how to enable it?
The expression "[:xdigit:]" that you're using will match any of the characters ":", , "x", "d", "i", "g" or "t". Use "[[:xdigit:]]" to match a hex digit character.
