XML Validator

XML Validator guide

Check whether your XML is valid.

Input and limitations

Well-formed XML. Nested structures and attributes are supported.

Check the selected options before using the result. Formatting and conversion do not establish that data is safe or suitable for your application.

How to use XML Validator

  1. Paste your XML into the Enter XML Content field.
  2. Validation runs automatically as you type.
  3. The result appears below the input.
  4. Click Clear to empty the input and remove the validation result.

Example

Try <root><name>Ada</name></root>, then remove </root> to see a well-formedness error. Well-formedness is not schema validation.
