Well, feel free to send any ideas or help to me! It seems simple... Do a binary read. Find 'stream' and 'endstream' sections. zlib.decompress() all the streams. Find BT and ET markers (Begin Text & End Text) and finally locate the parens within those and string the text together. This works great on 3 out of 10 PDF documents, but my main issue seems to be the zlib compressed streams. Some of them don't seem to be FlateDecodeable (although they claim to be) or the header is somehow incorrect. But, once I get a good stream and decompress it, things are OK from that point on. Seriously, if you have ideas, please let me know. I'll be glad to share what I've got so far. Not many people seem to be interested. I'll stop adding to this thread... I don't want to beat a dead horse. Anyone interested in helping, can contact me via emial. Thanks, Brad -- http://mail.python.org/mailman/listinfo/python-list
