I think I tried xdocdiff once, and I think it is text only.

If you use Cygwin, you can try pdftotext, which is part of the xpdf
Cygwin package, which is text only.

You can also try the OpenOffice PDF Import extension
(http://wiki.services.openoffice.org/wiki/Pdf_Import_Extension),
importing, and then performing a diff using OpenOffice. If you can do
it this way, it is probably scriptable. I have not used this myself.
