How XML Formatter & Validator works
XML formatting makes element hierarchy visible through indentation while validation checks whether the document is well formed. This helps reveal missing closing tags, invalid nesting, and difficult-to-read machine-generated XML.
The browser parses the document as XML and checks for parser errors. A valid tree is serialized with line breaks and indentation so parent, child, attribute, and text relationships can be inspected more easily.
Well-formed XML is not automatically valid against a DTD or XSD schema. Namespaces, mixed text content, and whitespace-sensitive documents deserve extra review because visual formatting may affect how some consumers interpret text nodes.
