Validate RSS and Atom Documents

Use an online validator to check your RSS and Atom documents.

You can check RSS 0.91, RSS 1.0, RSS 2.0, and Atom documents online using Mark Pilgrim and Sam Ruby’s Feed Validator (http://feedvalidator.org). The project is hosted on SourceForge (http://sourceforge.net/projects/feedvalidator/). This hack will use Feed Validator to check an RSS or Atom document.

Go to http://feeds.archive.org/validator/ and in the text box, enter the URL http://www.wyeast.net/news.rss (0.91) as shown in Figure 6-4, or an Atom document, http://www.wyeast.net/atom.xml. (The scheme name http:// is already provided in the text box.) Click the Validate button. The file is processed and the results are posted to the browser (Figure 6-5).
