Formatting XML safely
The formatter parses the markup before it changes indentation, so malformed tags produce an error instead of a formatted result. The XML plugin uses whitespace-sensitive formatting because spaces between text nodes may be meaningful in some documents.
Formatting changes presentation and may normalize quotes or empty-element syntax. Keep the original file and compare results when a consuming system depends on exact whitespace or serialization.
