我想将 BuildingCode 设置为主键并验证 building.xml 文件.我添加了一个名为 PKBuildingCode 的键，但即使在 xml 文件中添加重复的 BuildingCode，它也不会验证 xml 文件.有人可以帮我解决问题吗?

I want to set the BuildingCode as primary key and validate the buildings.xml file.I added a key named PKBuildingCode but it is not validating the xml file even if add duplicate BuildingCode in the xml file. Can someone help me in solving the problem??

推荐答案

你可能只想要 xsd:unique:

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

另见:

xsd:key 和 xsd:unique 的区别
