Typical use cases

Check sitemaps and feeds

XML sitemaps, RSS feeds and Atom feeds can be formatted for readability and checked for basic parser errors.

Inspect interfaces

XML responses from APIs or web services can be reviewed, copied and prepared for testing.

Clean up configurations

XML configuration files become easier to read when elements, attributes and nesting are indented consistently.

Note: The check validates the basic XML structure in the browser. It does not replace schema validation against XSD, DTD or specific feed rules.
