Hi Alexander. Thanks for the reply. Instead of using the content method of Mechanize::Firefox I used CAM::PDF to extract the text from each PDF page and then search the text for my filter phrases. The only wrinkle is that I have to save the URL in a file and then load the file into CAM::PDF. When the script ends I get multiple clean up errors about removing a call back on an undefined value. This does not affect the script in any way.
