- <description> - Describes the channel (e.g. Spotfire Analytics)
Each <channel> element can have one or more <item> elements.
Each <item> element defines an article or "story" in the RSS feed.
The <item> element has three required child elements:
- <title> - Defines the title of the item (e.g. Spotfire Today)
- <link> - Defines the hyperlink to the item (e.g. http://www.spotfire.tibco.com/en-xml-rss.html)
- <description> - Describes the item (e.g. All you need to know about Spotfire)
Finally, the two last lines close the <channel> and <rss> elements.
