W3 Validation of Angular code online

If you tried to validate your AngularJS code with http://validator.w3.org/, you must have noticed that it does not allow AngularJS ng-* attributes.

The W3C HTML5 validation team has developed a tool which allow to filter errors during the validation, and accept well ng-* attributes.

You can try it at this URL: http://validator.w3.org/nu/

After you submit a document for checking, on the results page you’ll see a Message filtering button, and if you press that, you’ll get a list of all the error messages grouped into sets, with Show/Hide checkboxes.
