XML Validator (Well-formedness Check)
Check if your XML data is well-formed (syntactically correct). DTD/XSD validation is not supported client-side.
About the XML Validator Tool
The XML Validator checks if your XML (Extensible Markup Language) data is 'well-formed'. Well-formed XML adheres to basic XML syntax rules, such as proper tag nesting, correct attribute quoting, and having a single root element. This tool performs a syntax check but does not validate against a DTD (Document Type Definition) or XSD (XML Schema Definition) client-side.
Why Use This XML Validator?
Ensuring XML is well-formed is the first step before it can be processed by any XML parser or application. Errors in well-formedness will cause parsing to fail. This tool helps you quickly identify syntax errors in your XML documents, making debugging easier.
Example Use Cases
- Checking an XML configuration file for syntax errors before deployment.
- Validating XML data received from an API or external source.
Pro Tips
- Error Messages: The tool uses the browser's built-in XML parser. Error messages often provide line and column numbers to help pinpoint the exact location of the syntax issue.
