About this tool

Paste XML to check that it is well-formed — properly nested tags, matching closing tags and a single root element. If parsing fails, the browser parser's error message is shown to help you locate the problem.

Examples

  • <root><a>1</b></root> is invalid because the closing tag does not match.
