This is a validator for syndicated feeds and works with RSS 0.90, 0.91, 0.92, 0.93, 0.94, 1.0, and 2.0, and Atom feeds. Enter the address of your feed and click Validate. If the validator finds any problems in the feed, it will give a message for each type of problem and highlight where the problem first occurs in the feed. If the messages are unclear, 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 and elements from some commonly used namespaces like Dublin Core.
