The problem is that the maximal ("greedy") match consistent with the + in your regexp extends all the way to the last mousedown in the string. Just put a ? after the +, to force a minimal instead of the (default) maximal match.

BTW, I don't see how the use of regexes to weed out unwanted URLs argues in favor of using them to parse HTML. The latter is a much harder problem, due to the presence of nested balanced delimiters. So much harder, in fact, that "true" regular expressions (as opposed to Perl's regexes-on-steroids) cannot solve it.

I think you are far better off with HTML::LinkExtor or HTML::TokeParser to extract the links. Here's how you'd do it with HTML::TokeParser:

my $parser = HTML::TokeParser->new( \$google_results ); my @links_found; while ( my $token = $parser->get_tag( 'a' ) ) { my $url = $token->[ 1 ]{ href }; next unless $url =~ m{^http://www\.}; push @links_found, $url; } print "$_\n" for @links_found; __END__ http://www.ets.org/toefl/ http://www.ets.org/testcoll/ http://www.test.com/
