xsd:keyref上的验证错误

Question

我想要将job元素的jobGroup属性与jobGroup元素的name属性“匹配”，但是我无法通过验证来验证这个约束

这是我的模式和应该失败的示例。

Answer 1

您忘记在选择器中使用完全限定的名称。您丢失了命名空间。

试试这个：

<xs:element name="cluster" type="tns:clusterType">
    <xs:keyref name="jobGroupKeyRef" refer="tns:jobGroupKey">
        <xs:selector xpath=".//tns:job"></xs:selector>
        <xs:field xpath="@jobGroup"></xs:field>
    </xs:keyref>
    <xs:key name="jobGroupKey">
        <xs:selector xpath=".//tns:jobGroup"></xs:selector>
        <xs:field xpath="@name"></xs:field>
    </xs:key>
</xs:element>
