What is XML validation?
XML validation checks well-formedness: matching start and end tags, properly quoted attributes, a single root element, and correct entity references. Unlike schema validation, well-formedness is a syntax check that every XML parser requires before it will read the document.
FAQ
Does this check against a schema (XSD, DTD)?
No. It checks well-formedness only. Schema validation would require fetching or providing the schema, which is a different operation.
Are external entities loaded?
No. The browser parser does not fetch external entities, which prevents XXE attacks.
Is my XML sent anywhere?
No. Parsing uses the browser's built-in XML parser.
