For a general solution you must know the geometric bounds of the header and
footer. You then compare the x/y location of each text string (that is,
contiguous sequence of characters within the PDF data stream) to see if they
are within or without that boundary (with some heuristic for overlap).

If the publications you're operating on are consistent in their page layout
then this can be relatively easy, but if they're not, you may need to have
humans do "zoning" on each page manually by some means (e.g, you build a
visual tool or use Acrobat to add boxes or whatever).

If the header and footer contents are consistent you may be able to
recognize them just be looking at the text content but that depends on the
details of the document's you're processing.

Cheers,
