XSD validation for unsorted and only one unbounded element

I have an xml file like this:

<customer>
  <field1 />
  <field2 />
  <field3>
    <item1 />
  </field3>
  <field3>
    <item1 />
  </field3>
</customer>
Field

* can appear in any order, and only field3 can appear more than once.

How do I create an XSD file to test this?

Thank!

Try

I'm not a guru, but it works.

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:element name="customer" type="customerType"/>
  <xs:complexType name="customerType">
    <xs:sequence>
      <xs:element name="field1" minOccurs="1" maxOccurs="1">
      </xs:element>
      <xs:element name="field2" minOccurs="1" maxOccurs="1">
      </xs:element>
      <xs:element name="field3" type="field3Type"
                  minOccurs="1" maxOccurs="unbounded"/>
    </xs:sequence>
  </xs:complexType>
  <xs:complexType name="field3Type">
    <xs:sequence>
      <xs:element name="item1">
      </xs:element>
    </xs:sequence>
  </xs:complexType>
</xs:schema>

I've used XML Copy Editor , but there are many editors out there that will validate XML.

Hum, this is the kind of work that xsd is really not comfortable with. Anyway, this should do the trick, if I'm not mistaken:



<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="http://www.example.org/NewXMLSchema"
xmlns:tns="http://www.example.org/NewXMLSchema" elementFormDefault="qualified">

  <element name="customer" type="tns:customerType"/>
  <complexType name="customerType">
    <sequence>
      <element>
        <complexType>
          <all>
            <element>
              <complexType>
                <sequence>
                  <element ref="tns:field3" maxOccurs="unbounded"/>
                  <element ref="tns:field1" maxOccurs="1"/>
                </sequence>
              </complexType>
            </element>
            <element>
              <complexType>
                <sequence>
                  <element ref="tns:field3" maxOccurs="unbounded"/>
                  <element ref="tns:field2" maxOccurs="1"/>
                </sequence>
              </complexType>
            </element>
            <element>
              <complexType>
                <sequence>
                  <element ref="tns:field3" maxOccurs="unbounded"/>
                  <element ref="tns:field4" maxOccurs="1"/>
                </sequence>
              </complexType>
            </element>
          </all>
        </complexType>
      </element>
      <element ref="tns:field3" maxOccurs="unbounded" />
    </sequence>
  </complexType>
  <complexType name="field1Container"/>
  <complexType name="field2Container"/>
  <complexType name="field3Type">
    <sequence>
      <element name="item1"/>
    </sequence>
  </complexType>
  <complexType name="field4Container"/>
  <element name="field3" type="tns:field3Type"/>
  <element name="field1"/>
  <element name="field2"/>
  <element name="field4"/>
</schema>
