XML Schema Validator

About the tool

An XML schema defines the structure of an XML document. Validating an XML document against an XML schema ensures that the XML document adheres to the rules defined in the schema. This is useful when you need to ensure that the XML document is in a specific format before you can process it.

I've built this tool to allow you to validate XML against XML Schema (XSD) in the browser. The tool uses the WASM port of the xmllint library and performs the validation synchronously on the client side (no data is sent to the server).
