This is a sample RSS 2.0 feed that uses several allowable extension modules in namespaces. The feed is annotated with links that show how each value can be accessed once the feed is parsed.
Caution
Even though many of these elements are required according to the specification, real-world feeds may be missing any element. If an element is not present in the feed, it will not be present in the parsed results. You should not rely on any particular element being present.
