Reading an RSS Feed
RSS (Really Simple Syndication) feeds allow websites to provide a structured listing of content that can be parsed out across various tools such as news aggregators, social sites, and so on. RSS feeds are created using a specialized XML format that makes it easy to parse through.
Getting ready
