Validate XML structure and root

For checking an exchange, configuration file or service response before use, XML Validator identifies structural faults and the root.

Check an XML document for structural errors and inspect its root before integration or exchange. You get the result directly in your browser.

How to use

Paste the XML you want to check into the input area or import the file.
Run validation to detect structural errors and identify the root.
Read the result to find unclosed tags, bad nesting or invalid characters.
Fix the source, then run validation again until the document is accepted.

Example

A developer receives an XML response from a service and wants to check that it can be used. They paste the content, run validation and inspect the root along with any errors. This prevents them from integrating a broken response into their application.

Limits and formats

Validation checks XML well-formedness, not compliance with a business schema.
A well-formed document may still be incorrect for your application.
Reported errors depend on the parser used and may require manual correction.
Very large or badly encoded files may not be processed correctly.

Where processing happens

Everything runs in your browser: the XML document is parsed locally to check its structure. The content you provide is never uploaded, shared or stored.

Frequently asked questions

What is the difference between well-formed and valid?

Well-formed XML follows syntax rules, such as closed tags and a single root. Valid XML also follows a schema or business rules. This tool mainly checks well-formedness and shows the root element.

Does the tool always show the exact line of the error?

The result helps locate the problem, but the position may be approximate depending on the error. Use the message as a starting point and inspect the tags close to the reported area.

Can I validate XML with multiple roots?

No, an XML document must have a single root. If your content contains several top-level elements, wrap it in a root tag before running validation again and checking the structure.
