About the XML Validator
Well-formed XML must have matching tags, properly quoted attributes and a single root element. This validator uses the browser's native XML parser to detect violations and report the parser's error message, helping you fix structural problems quickly.
Validation is private and instant, making it safe to check XML that contains sensitive data.
