Generate sample XML from an XSD

Need a test file for an interface, an example for documentation, or a starting point for a message you have to write by hand? Pick an element in the tree and choose Sample XML.

Required content first — the minimal document that satisfies the schema, with the first branch of each xs:choice and the first enumeration value.
Everything optional on request, and repeating elements shown up to three times.
Plausible values — names suggest them (Currency → EUR, Email → an address, ISIN → a real ISIN), dates and numbers vary between occurrences, and patterns, lengths and ranges are respected.
Checked against the schema, so you know whether the sample is valid as generated.
Copy, download, or open in the XML Viewer to browse it as a tree.

From the command line

The same validation is available through the REST API: post a schema and an XML document and get a JSON list of errors with line numbers — useful in CI pipelines that produce XML.

Questions

Is the generated XML valid?

The generator checks every sample against the schema. In rare cases — very unusual patterns or XSD 1.1 assertions — a value may not fit; the check tells you, and such cases are reported so the generator can be improved.
