About Free Online XML Validator

Our Strict XML Validator checks your codebase directly against the core browser DOM parsers to ensure your XML trees contain standard encodings, perfectly matched tags, and non-breaking hierarchies.

🚀 Structural Checking

Catch subtle missing closing tags, unescaped ampersands, or illegal characters automatically. If the internal browser XML DOM fails to parse your layout, this tool throws the exact error location.

⚡ Syntax Highlighting

It features advanced Ace editor logic, displaying colored syntax blocks that make spotting stray attributes and incorrect node orders significantly more intuitive to humans.

🌐 No Logs, Super private

It protects API footprints by retaining everything inside your temporary browser cache layer. Rest easy validating configuration blocks without any API outbound queries.
