Frequently asked questions
- Does this validate against a schema (XSD)?
- No, this checks that the XML is well-formed (correctly nested, matched tags, valid syntax) but doesn't validate against a specific schema or DTD.
- Is my XML uploaded anywhere?
- No, parsing happens locally using the browser's native DOMParser — nothing is sent to a server.
