One easy way to do it is to split it into two scripts, and connect them with a pipe. In the first script you produce output to STDOUT, in the second you read from STDIN.

But in your case that won't help you at all, because you're slurping input into a variable at once, which means a chunk by chunk processing can't happen.

What you can do is to sest local $/ = 'END-OF-DOCUMENT' and thus read the file block by block (assuming you actually have multiple such blocks in your file).
