About XML Validation
XML (eXtensible Markup Language) is a text-based format designed to store and transport data in a structured way. Validation ensures your XML is well-formed and optionally complies with a defined schema, preventing errors when using it in applications, APIs, or configuration files.
Common XML Validation Errors:
- Missing or mismatched tags
- Improper nesting of elements
- Missing closing tags
- Unquoted attribute values
- Unescaped special characters
- Duplicate ID attributes
- Schema inconsistencies when using XSD
XML Schema Definition (XSD):
The XSD section in this validator is optional. When provided, our validator will check if your XML is not only well-formed but also adheres to the structure and constraints defined in your schema. XSD validation helps ensure your XML follows the expected format, including element types, allowed values, and required elements.
