XSD Validation
Checks whether an XML document conforms to a given XSD schema, using libxml's schema validator on our server (no external resources are ever fetched during validation).
How it works
Paste an XML document into the input panel, its XSD schema into the second panel, and click Validate.
Frequently asked questions
- Does this fetch any external schemas or DTDs referenced in my documents?
- No — network access is disabled during parsing and validation (LIBXML_NONET), so any xsd:import/include or external DTD reference is ignored rather than fetched. Include everything needed directly in the schema you paste.
