I don’t think you’ll need to modify the parse-plugin.xml because Tika (the
default parser) is capable of handling RSS feeds [1]. Second using the default

Don’t think you’ll find all your answers on the out-of-the-box nutch, but you
should study some of the extension points Nutch has, as far as I can see you
should be able of writing custom plugins that will allow you to achieve your

Like Raja said, it's possible the thing is that out of the box, nutch is only
