[Sage] an idea for improvement with regex

[Tymek W]

Hi,

I've got an idea for improvement to Sage. I subscribed to many RSS
feeds, but I'm looking there for specific informations - I don't read
everything. I thought it could be nice if it was possible for user to
make a rule for sage using regular expressions to filter feeds and make
of them one feed with summary of interesting news. It would be an extra
 feed called 'Summary' or something. For example: person subscribes to
some computer feeds and uses linux OS, he doesn't want to read news
about Windows crap because it doesn't interest him; he makes rules
filtering news with "linux" words in feeds. Of course someone could want
to filter different words or make regular expression rules for better
performance.

What do you think about that?

greetz,
