in thread Storing Substitution Output String

say your text is in a string (or an array of strings) then I would use grep and map :-) to get a list of all matches nicely formatted as list items, but for sure there is an easier way which refuses to come to my mind now :-)

perhaps this might do :-)

# the substitution is none in effect, it just digs around $page2 =~ s|<title>(.*)</title>|${my_count(\$1)}|gi; my matches = (); sub my_count { my $occurance = shift; push @matches, ${$occurance} ; return $occurance; } # see what we've got foreach (@matches) { print '<li>'.$_.'</li>'."\n"; # just to format the output :-) }

Have a nice day
All decision is left to your taste

Update

fixed stupid error in the substitutional part where I inserted the '<title>' again.
