in reply to Regex to match file extension in URL

How about:

$myvar =~ /\.html$/;

The $ will anchor the match to the end of the string.

If that wasn't what you wanted, could you provide examples of what you want as a result of the match?

    Sorry if that wasn't clear. What I need is a regex to match the extension of the remote file, whatever it is, not just if it's .html. The $myvar was just an example.

      If that's the case, then how about 
      if ($myvar =~ m/\.([^.]+)$/) {
print "Matched $1";
}

      Of course, this won't work for URL's with an implicit filename, like "http://www.yahoo.com" or "http://www.somewhere.com/home/" You'll have to catch those bad boys elsewhere in your code.

        Let me break this down and learn :) 
        \.    # literal period
    (    # start capture
        [^.]   # any character that's not...any character?
            +    # one or more of them
    )    # stop capture
$    # end of line
