The solution I discovered is this... `$contents =~ s/(<IMG\s.*?>)/&addalt($1)/sige; $contents =~ s!\>alt=\"\"! alt=\"\"\>!sig; print $contents; sub addalt { my $returned=shift; if ($returned!~m/\salt/){ $returned=$returned.'alt=""'; } return $returned; }` [download] The key I discovered was the "e" switch on the regex.

$contents =~ s/(<IMG\s.*?>)/&addalt($1)/sige;
$contents =~ s!\>alt=\"\"! alt=\"\"\>!sig;
print $contents;

sub addalt {
   my $returned=shift;
   if ($returned!~m/\salt/){
      $returned=$returned.'alt=""';
   }
   return $returned;
}
