Hello Fellow Monks

I have a problem that I beleive should be quite simple but I just don't know the syntax for what I want to do.

I have a file containing lots of documents separated by checkpoints identified by the special sequence af characters at the start of the line. Within the checpoint is a unique identifier.

In another file, I have a list of unique identifiers that I want to use to modify the checkpoint.

If I slurp the list of IDs into an array, then read the documents in one line at a time, how can I tell if any of the IDs in the ID list are contained in the checkpoint

Thanks in advance
