Come si annidano gli elementi complexType in un xsd?

Question

Ho un file xml e xsd che entrambi convalidano correttamente (testato su http://xsdvalidation.utilities-online.info/).

Tuttavia, l'xml non viene convalidato rispetto a xsd. Penso che questo sia dovuto al fatto che sto incoraggiando in modo errato elementi complexType in xsd, rispetto all'xml. L'elemento esterno di people sembra essere la causa del problema ...

Ecco il xml:

<?xml version = "1.0"?> 

<people> 
    <person> 
     <firstname>Joe</firstname> 
     <lastname>Schmoe</lastname> 
    </person> 

    <person> 
     <firstname>Cletus</firstname> 
     <lastname>Jenkins</lastname> 
    </person> 
</people> 

... e qui è il xsd:

<?xml version = "1.0"?> 
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> 

    <xs:element name = "people"> 
     <xs:complexType> 
      <xs:sequence> 

       <xs:element name = "person"> 
        <xs:complexType> 
         <xs:sequence> 

          <xs:element name = "firstname" type = "xs:string" /> 
          <xs:element name = "lastname" type = "xs:string" /> 

         </xs:sequence> 
        </xs:complexType> 
       </xs:element> 

      </xs:sequence> 
     </xs:complexType> 
    </xs:element> 

</xs:schema> 

Answer 1

Aggiungi maxoccurs="unbounded" all'elemento denominato "persona". È una sequenza di uno o più elementi di una persona.

Answer 2

Prova questo per il vostro XSD:

<?xml version = "1.0"?> 
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> 

    <xs:element name="people" type="people"/> 

    <xs:complexType name="people"> 
     <xs:sequence> 
      <xs:element name="person" type="person" maxOccurs="unbounded" minOccurs="0"/> 
     </xs:sequence> 
    </xs:complexType> 

    <xs:complexType name="person"> 
     <xs:sequence> 
      <xs:element name="firstname" type="xs:string" maxOccurs="1" minOccurs="1"/> 
      <xs:element name="lastname" type="xs:string" maxOccurs="1" minOccurs="1"/> 
     </xs:sequence> 
    </xs:complexType> 

</xs:schema>
