Test this regexes with foo <!-- bar --> baz <!-- qox --> blurb - it removes too much.

You could do something like this: $xml =~ s/<!--.*?-->//g;

Update: You can use the fact that '--' may not occur in xml comments:

$xml =~ s/<!--(?:.(?<!--))*-->//g;

Sadly lookarounds are error prone (from the programmer's side), so don't trust this regex unless you've tested it carefully. I don't think there is a big speed gain in it (if at all), I hope I find the tuits to benchmark it.
