regex - How can I match everything that is after the last occurrence of some char in a perl regular expression?

For example, return the part of the string that is after the last x in axxxghdfx445 (should return 445).

my($substr) = $string =~ /.*x(.*)/;

From perldoc perlre:

By default, a quantified subpattern is "greedy", that is, it will match as many times as possible (given a particular starting location) while still allowing the rest of the pattern to match.

That's why .*x will match up to the last occurence of x.
