cvc-complex-type.2.4.b: The content of element 'tns:patient' is not complete

Question

In the below xsd I am trying to create a list of 10 patients using the same schema. When I validate the xml file I get an error saying cvc complex type 2.4.b.Is there any other way I can use to create a list of 10 patients with the same schema definition.

XSD file:

Answer 1

The patient child of the patient root element of the XML has no children of its own, yet the XSD says that patient elements must have a sequence of various child elements (patient, name, age, etc).

If you want to have any hope of instantiating a valid XML document for your XSD, you'll at least have to make the patient child element be optional: minOccurs="0". Otherwise, your XSD will be specifying an infinite recursion of patient descendants. Note that by default, minOccurs="1", which means that the element is required.

If you want to allow your XML as-is (with an empty patient child element) to validate, similarly add minOccurs="0" to each of the declarations for name, age, dob, etc.
