I would start in the System.ServiceModel.Syndication
namespace, there are classes to directly manipulate RSS feeds. In particular, this looks promising:
XmlReader reader = XmlReader.Create("http://your.uri.here/feed.xml"); SyndicationFeed feed = SyndicationFeed.Load(reader);
Then explore the SyndicationFeed
class, in particular the Items
collection should contain the RSS entries.
