in reply to Regexp for range of numbers

I'm sure you have your reasons for wanting to do this with a regular expression , but surely the smart way to do it would be: 

   $number >= 0 and $number <= 255

numeric comparison is going to be faster as that is something that computers can do natively.

    Thanks for the reply. Actually I have other people's reasons for having to do this with a regexp. The regexp is an attribute in an XML file, which is at some point read by a Perl script.
