I’m hacking on a feed reader sort of thing right now, and experimenting with parallel feed fetching. I’ve spent a few hours this afternoon trying to find a perl-based feed reader module that will do RSS2.0 and Atom, and failure has dogged me in my travels. I’m not so bothered about the RSS2.0 stuff since I already have that covered, but I can’t find anything which will sensibly do Atom and has some reasonable documentation (the latter being probably where most things are failing right now).
Tried (so far): XML::Atom, XML::FeedLite, XML::RSS::FromAtom, XML::Atom::Syndication. Any others?
