RSS feed validation is a validator for syndicated feeds. It works with RSS 0.90, 0.91, 0.92, 0.93, 0.94, 1.0, 1.1, and 2.0. It also validates Atom feeds.
To use it, simply enter the address of your feed and click Validate. If the validator finds any problems in your feed, it will give you messages for each type of problem and highlight where the problem first occurs in your feed. If you're unsure what a message means, click the "help" link next to the message for a fuller explanation.
It validates RSS feeds against the rules defined in the RSS 2.0 specification. It also validates elements of commonly used namespaces:
- Dublin Core
Note: For Atom feeds, it validates against RFC 4287, which describes version 1.0 of the Atom feed format.
RSS validator is an attempt to codify the specification to make it easier to know when you're producing RSS correctly, and to help you fix it when you're not.
The validator also supports the IETF standard Atom format for syndicated feeds.
There are validators for other web technologies, such as HTML, CSS, and accessibility guidelines, and these have all proven quite popular. As personal news syndication is becoming more widespread, we saw a need for a comprehensive but easy-to-use validator for syndicated feeds.
Mainly RSS validator is used to check the syntax.
