Read RSS - not return a link with the same page

[Israel]

Hi,

I have this problem: My Nutch read rss, for example RSS:


http://www.edutube.org/en/taxonomy/term/7/feed

But I want that Nutch perform searches within the links (links),.... and
that not return the RSS in search results.... that is, not return a link
with the same page

http://www.edutube.org/en/taxonomy/term/7/feed


Somebody have some plugin; or know how i can do it?? the steps

Thanks.
