What is RSS?

RSS is a form of site content aggregation.

Its name is the abbreviation of Really simple syndication .

RSS is one of the XML. All RSS documents follow the XML 1.0 specification , which is posted on the Web site.

here is an overview of the RSS version history.

In an RSS document, the outermost layer is a <rss> element that must specify the version attribute, which makes clear what RSS version specification this document complies with. If an RSS document is represented by this specification, then its version attribute must be 2.0.

The <rss> element has only one child element <channel>, and contains some information about the channel (metadata) and its contents.

Sample file

Here are some RSS sample files: RSS 0.91, 0.92 , and 2.0.

Note that the link addresses and servers that these sample files point to May no longer exist. By the time the 0.91 document was written, this 0.91 sample file had been created. The history of maintaining a sample file may be a good idea.
