Validate XML well-formedness before using the document in another system

XML must follow structural rules for elements, attributes, escaping and nesting. A validator helps detect malformed markup before the file reaches an application.

Well-formed XML is not automatically valid against a particular schema. Schema rules and business requirements are additional checks.

Useful XML-validation workflows

  • Find mismatched or unclosed tags.
  • Check generated XML before sending it to another service.
  • Review markup after manual editing.

What validation means

  • Well-formedness is different from schema validity.
  • Correct syntax does not guarantee correct business data.
  • Namespaces and encoding declarations may also matter to the destination.

Before relying on the result

Keep the source until you have checked the generated output. The source and destination formats can represent structure, layout and metadata differently, so important documents should be reviewed in the application or device where the result will actually be used.
