We're (my Perl script and I) reading binary data from a dBase file. One piece of data is a 4-byte string, which may contain trailing zero bytes: 4A 04 00 00, say, or F6 00 00 00.

I want to remove the trailing zeros, if there are any. I was thinking a regexp would be the prime tool (especially seeing as I'm a regexp idiot at this point, and want to improve).

I tried s/(\x[01-FF]+)\x00/$1/ as something of a stab in the dark (can Perl even interpolate a range of hex values?) - it didn't substitute anything; the hex string comes back unchanged.

What's wrong with my regexp? What regexp(s) would work? Am I foolish for even using a regexp?

Many thanks...
