XML Validator

XML Validator allows you to check whether an XML document is correctly structured and follows the basic syntax rules required for valid XML. You can paste XML directly into the tool or select an XML file from your device.

To validate a document, add your XML and click Validate XML. If the document is valid, the tool confirms that the XML is correctly structured. If there is an error, the validation result identifies the problem so you can find and correct the invalid part of the document.

For example, this XML contains a syntax error:

<user>
  <name>CodeLiqo</name>
  <role>developer<role>
  <active>true</active>
</user>

The problem is the role element. It starts with <role> but does not have the corresponding closing tag </role>. XML elements must be properly opened and closed, so this prevents the document from being valid.

XML Validator is useful when working with API responses, configuration files, data exports, integrations, or XML documents that need to be checked before being processed by another application. Validating XML before using it can help identify syntax problems early and make troubleshooting easier.

The tool works directly in your browser, so you can quickly check XML without installing additional software. It is also useful during development when creating or modifying XML and you want to verify that the document remains correctly structured.
