Let's look at an example of RSS. The National Aeronautics and Space Administration (NASA) maintains many RSS feeds, and you can see a list of them on the [NASA RSS Feeds](https://www.nasa.gov/content/nasa-rss-feeds) page. Go there now and select the [Breaking News](https://www.nasa.gov/rss/dyn/breaking_news.rss) feed which is at this URL:
<description>NASA Administrator Bill Nelson will speak to elementary school students about the future of space exploration Monday, May 9, and tour a lab working on robotic construction technologies Tuesday, May 10, during a trip to Florida.</description>
<description>NASA’s SpaceX Crew-3 astronauts aboard the Dragon Endurance spacecraft safely splashed down Friday in the Gulf of Mexico off the coast of Florida, completing the agency’s third long-duration commercial crew mission to the International Space Station.</description>

Observe the structure of the XML document. It describes a `feed` that has some metadata such as title, id, logo and information as to when it was last updated. That `feed` contains one or more `entry` elements, each of them representing a post in the list tagged with "ABAP Development". Think of this like a document, with a header and items.
