Hmm, it is a bit difficult to state the position of an unmatched text pattern... More generally, the idea should probably be to use a regex to check if you can match "doesn't" or "don't", but you don't give enough details on the circumstances. May be something like: 
if ($string =~ /doesn't/ or $string =~ /don't/) {
     do_something();
} else {
     something_else();
}
