Re: PDF Parsing Revisited

[Doug Cutting]

I'm currently using xpdf's pdftotext program to parse pdf, via the parse-ext plugin. It seems much faster than PDFBox.

To try it, copy the attached plugin.xml file to

  build/plugins/parse-ext/plugin.xml

then copy the attached parse-pdf.sh script to

  bin/parse-pdf.sh

and make it executable

  chmod +x bin/parse-pdf.sh

finally, include the parse-ext plugin in your nutch-site.xml.

What do you think?
