Frequently Asked Questions (FAQ)
Does this tool validate XML?
Yes. Well-formedness is checked — unclosed tags, illegal characters, and mismatched namespaces are flagged with error messages.
Can I minify XML?
Yes. The 'Minify' option removes all whitespace and indentation, producing compact XML suitable for API payloads.
Is DTD or Schema validation supported?
This tool checks XML well-formedness only. Full DTD/XSD schema validation is not currently supported.
