Really Simple Syndication, or RSS, is a dialect of XML that is commonly used for providing news-related content. Things such as news headlines are the realm of RSS. The only issue is that because RSS is XML, it doesn't appear as pretty as HTML does in a web browser. Consider the RSS shown in Listing 7-4 as an example.
