Using CAM::PDF, you can parse the document and find the string that corresponds to what you're looking for. As for how? I dunno. You might want to look at the source for
Test::PDF which uses
CAM::PDF to verify that two PDFs contain the same data and structure and see what
stvn does there.
My criteria for good software:
- Does it work?
- Can someone else come in, make a change, and be reasonably certain no bugs were introduced?
