Did you read my previous message in this thread? If you have, then
you've just committed a strawman, and that's unlike you.

(And for the record, the complement of «*.doc» is «*[^c]|*[^o]c|*[^d]oc|*[^.]doc|».)

I'm aware of that, and have said so in so many words, but the problem
statement was "Ignore everything except XX* and YY*", and that _can_ be
achieved with negated patterns.

At this point I'd rather wait for Daniel to answer my question and
clarify his problem statement.
