XML Validator
Check whether an XML is well-formed: correctly opened and closed tags, proper nesting, and a single root element.
What it checks and what it doesn't
This tool validates that the XML is syntactically correct ("well-formed"): closed tags, valid nesting, a root element. It does NOT validate against an XSD schema or check that the data makes sense for your specific case — that would require the schema itself, which this tool doesn't process.
