What is an XML Validator?

An XML Validator checks if your markup is 'well-formed' (tags are correctly closed and nested, attributes have valid values, and standard declarations are present).

Does this validate against DTD or XSD schemas?

Currently, this validator checks XML well-formedness. Schema validation (DTD/XSD) is not supported.
