I agree with aragorn with getting rid of the die. I would not even bother with the warn unless I wanted to watch it. I think that it would better to send your errors to a log file with the file_name or any other stats so you can continue to process the correct files that would include logging files we can't open perhaps. Also, you are performing a regex on the return value which may be undef. I would think you should do the regex before you return the field if (log that too) in case that doesn't meet your criteria so you can be sure you have a valid return.
