Just wanted to say: It works really nice! And it seems to make
easy to tackle the problem of all those different feed formats.
I've just yesterday released AnyEvent::Feed, which is a nice
convenience wrapper around AnyEvent::HTTP and XML::Feed. It works
really well for me :) Without XML::Feed I would've stayed out of
the Web 2.0 feed world :-)
I have several blogs. Now, in order for them to be syndicated in a certain Planet, I was instructed to aggregate all their feeds into one feed. At first, due to the constraints imposed by the Debian Woody that my remote system had, I used an Evil hack with a patched XML::RSS::Aggregate, a patched XML::RSS module, and lots and lots of evil logic.
Now I converted everything to using XML::Feed and just upload the RSS feed to the server (which is Sarge now). My code is so clean it isn't even funny. I've also used XML::Feed to syndicate my home site blog as news on my homepage.
