No, that won't work. The [^gallery] bit is saying "... and doesn't contain a g, a, l, e, r, y after the slash after the domain". While there's plenty of magic in regexes to let you solve the problem, I don't bother trying so hard for things like this. If it were me, I'd try doing it in two steps, like so:

$ cat t.pl use strict; use warnings; while (<DATA>) { if (m".*?/(.*?)/" and $1 !~ m"gallery"i) { print "Match: $_"; } else { print "No match: $_"; } } __DATA__ foo bar/baz/boffo bar foo/gallary/gallery bim bam/gallery/blam/blim arg blarg/gallery/flarg $ perl t.pl Match: foo bar/baz/boffo Match: bar foo/gallary/gallery No match: bim bam/gallery/blam/blim No match: arg blarg/gallery/flarg

As you can see, I first check to see if it matches the overall form of the URL and capture the contents of the first thing between slashes. The second part of the if statement checks to see whether the thing I captured matched the string I don't want to see.

Also, to make the regex look a little less confusing, I used the m"regex" so I wouldn't have to have all the backslashes before the forward slashes.

When your only tool is a hammer, all problems look like your thumb.
