我的要求是有一个XSD文件,它根据属性值检查元素.我能够将XSD编写到可以限制Application / @Type的属性值的位置.任何人都可以帮我完成XSD文件,我可以根据Application / @Type属性制作一些所需的元素吗?
我要实现
>只有当Application / @ Type为“Batch”时才需要PackageArg
>仅当Application / @ Type为“Service”时才需要版本
>仅当Application / @ Type为Web“或”Service“时才需要项目
XML文件
- <Applications>
- <Application Name="ConfigManagement" Type="Web">

- </Application>
- <Application Name="Util" Type="Web">

XSD文件

更新:OP已编辑问题以删除xs:assert的使用,并在评论中声明验证必须在C#中进行. OP问题的答案现在变为:
您不能使用XSD 1.0强制执行基于属性值改变元素要求的约束,并且Microsoft不支持XSD 1.1,因此您必须放松约束或在XSD之外检查它们.
原XSD 1.1的答案
(留作未来读者的利益)
你很亲密,但你的断言,
- <xs:assert test="count(./PackageArg[@type eq 'Batch']) eq 1"/>
当它应该在Application上测试@Type时,对PackageArg上的@type进行测试.
以下XSD将验证您的XML并强制执行依赖于属性的要求:
