Don't do the refind() in the loop. Running it once with "all" specified
will return (you're right on this one) a struct of arrays. It will find
all of the matches (hence scope "all" :-P).
You then only need to loop over the results. Much more efficient.
Plus, OMG, you're using a condition that runs the regex and throws away
the answer. Don't do that. Ever. Please. It makes me weep.
