Python fuzzy binary/ascii file difference checker function

Python file compare routine. I need a small Python function to compare similar files. The routine should examine and compare file A and B, returning true or false if they match or not. The trick I need is that I know for sure the files will never be exactly identical. They are PDF files which are part ASCII and part binary streams. The files will normally be different in three or more areas, because of date stamps and ID tags in the files. If these are the ONLY differences, I need the filter to return True, ignoring these small differences. The three areas are all in ASCII sections of the PDF, so are easy to spot. Basically, lines such as: /CreationDate (D:********) /M (D:***********) /ID [ *********** ] There might be more than one /M line. I want these three cases IGNORED in the file comparison test. I can't use a simple ASCII loop because of the presence of stream binary-stuff.... endstream Differences in any other area, including the binary streams, should return false. Hopefully this is a simple job for someone who codes python night & day. It will go into an existing python regression test suite. I don't need a full technical document report, just a working python routine with good in-line comments. I prefer it does not depend on extra packages, just what is native in current python installs. Oh, and I need it to work on Python 2.5, windows XP environment. I've attached file A & B samples plus a difference report so you can see exactly what the problem is before bidding. Thanks to everyone that bids, I need some help!
