RSS 2.0 uses a <rss> root with a <channel> and <item> elements. Atom 1.0 uses a <feed> root (in the Atom namespace) with <entry> elements. The validator detects the type and applies the right rules.

Fetching a URL from the browser is subject to CORS. If the feed server doesn’t allow cross-origin requests, you’ll get a network error. Open the feed URL in your browser, copy the XML, and paste it into the validator instead.

RSS 2.0: <channel> must contain <title>, <link>, and <description>. Each <item> should have <title> or <description>. Atom 1.0: Feed must have <id>, <title>, <updated>. Each <entry> must have <id>, <title>, and <updated>.

No. Validation runs in your browser. When you enter a URL, the request is made from your browser to that URL (subject to CORS). No feed content is sent to our servers.
