About XML Validation

XML Validator checks whether your XML is syntactically well-formed, including properly nested elements, valid closing tags, attributes, quotes, and XML structure.

A valid XML document must have one root element containing the rest of the document structure.

This tool performs syntax validation only. It does not validate an XML document against an XSD, DTD, or external schema.

All processing happens locally in your browser. Your XML data is never uploaded to a server.
