XML (eXtensible Markup Language) is a widely used format for storing and transporting structured data. Validating XML is crucial to ensure that documents are well-formed and conform to expected schemas, preventing errors in applications that process this data.
XML validation is the process of checking if an XML document follows the syntax rules of XML (well-formedness) and optionally conforms to a schema definition (validity). It's important because valid XML ensures proper data interchange between systems, prevents parsing errors, and maintains data integrity in applications that rely on XML.
Our XML validator performs two main checks: well-formedness (ensuring the XML follows proper syntax like balanced tags and correct nesting) and optional schema validation against XSD or DTD. It processes your XML entirely in your browser for complete privacy, provides detailed error messages with line numbers, and offers suggestions to fix common XML issues.
The tool supports checking XML well-formedness (proper structure), validation against XML Schema Definition (XSD), validation against Document Type Definition (DTD), and includes checks for common XML issues like encoding problems, namespace errors, and character entity issues.
Absolutely! Our validator processes your XML entirely within your browser—no data is ever sent to our servers. This provides complete privacy and security, making it safe to validate even sensitive XML documents without concerns about data exposure.
Yes! You can upload or paste your XML Schema Definition (XSD) file, and our validator will check if your XML document conforms to the rules defined in that schema. The tool provides detailed validation reports that help identify exactly where and how your XML fails to meet schema requirements.
Our free XML validator is here to help you ensure your XML documents are error-free and schema-compliant.
