我想将BuildingCode设置为主键并验证buildings.xml文件。我添加了一个名为PKBuildingCode的键，但即使在xml文件中添加了重复的BuildingCode，它也没有验证xml文件。有人可以帮助我解决问题吗？

Answer 1

您可能只想要xsd:unique：

<xs:unique name="PKBuildingCode">
    <xs:selector xpath="building"/>
    <xs:field xpath="BuildingCode"/>
</xs:unique>

另见：

Difference between xsd:key and xsd:unique

如何在xsd文件中定义xml主键并在xml文件中进行验证
