Frequently Asked Questions
How does XML validation work?▼
The tool uses the browser's native DOMParser to parse your XML. If parsing fails, the error message shows the exact location and nature of the problem.
What XML errors can be detected?▼
Missing closing tags, mismatched tag casing, invalid characters in element names, malformed attributes, duplicate attributes, and incorrect XML structure.
What is the difference between XML and HTML validation?▼
XML is stricter than HTML. All tags must be closed, attributes must be quoted, and element names are case-sensitive. XML validation catches all these issues.
Does this tool upload my XML?▼
No. All validation happens locally in your browser using the native DOMParser API.
