Question

我有两个具有相同名称但属性不同的子元素。有没有办法为它编写有效的XSD。

我现在得到的错误是：模型组中出现了具有名称链接和不同类型的多个元素

我有这样的XML：

        <entry>
            <id> 123 </id>
            <link rel="alternate" type="text/html" href="ABC.html" />
            <link rel="amphtml" href="https:ABCD.html" >
              <inline:inline type="text/html">
                <![CDATA[
                  <!doctype html>
                  <html amp>

                  </html>
                ]]>
              </inline:inline>
            </link>
        </entry>

我正在定义XSD：

        <xs:element name="entry" type="atom:entryType"/>
        <xs:complexType name="entryType">
              <xs:annotation>
                 <xs:documentation>
                    The Atom entry construct is defined in accordance with the XML defined in Just-in doc.
                 </xs:documentation>
              </xs:annotation>

              <xs:choice maxOccurs="unbounded">
                 <xs:element name="id" type="atom:idType"/>
                 <xs:element name="link" type="atom:linkType" minOccurs="0" maxOccurs="unbounded"/>
                 <xs:element name="link" type="atom:secondLinkType" minOccurs="1" maxOccurs="unbounded"/>
                 <xs:any namespace="##other" minOccurs="0" maxOccurs="unbounded"/>
              </xs:choice>

              <xs:attributeGroup ref="atom:commonAttributes"/>
           </xs:complexType>

    <xs:simpleType name="KnownRelCodeType">
          <xs:restriction base="xs:string">
             <xs:enumeration value="alternate">
                <xs:annotation>
                   <xs:documentation>
                   The value "alternate" signifies that the IRI in the value of the href attribute identifies an alternate version of the resource described by the containing element.
                   </xs:documentation>
                </xs:annotation>
             </xs:enumeration>

          </xs:restriction>
       </xs:simpleType>

                </xs:annotation>
             </xs:enumeration>

       </xs:simpleType>


       <xs:simpleType name="SecondRelCodeType">
          <xs:union memberTypes="atom:SecondKnownRelCodeType xs:string"/>

    <xs:complexType name="linkType" mixed="true">

             The Atom link construct is defined in section 3.4 of the format spec.

          <xs:attribute name="type" type="xs:string" use="required"/>

不，XML兄弟元素的名称不能相同，但在XSD中输入的方式不同。

为元素赋予不同的名称，或者为两者使用相同的类型，可能使用可选性来适应各种类型所提供的可能性的结合。

XSD用于具有两个同名元素的XML
