RSS feeds are received as xml and are then displayed at the receiving computer in html.
Thus 'raw' xml' content looks a little like html with similar 'markup' features.

Sometimes you are able to use a website’s features to display an RSS feed.
RSS feeds may be generated by blogs like this one
They enable to user to monitor additions to the blog
The text version of podcasts are also often available as an RSS feed.
RSS feeds thus enable the user to select sources of information and keep up to date without having to remember to visit the original website.
The source site pushes the RSS feed out, the receiving end pulls the RSS feed in.
