我正在尝试查询此 XML 文件第 11 行的代码库属性。

<?xml version="1.0" encoding="utf-8"?>

        </dependentAssembly>
    </dependency>
</asmv1:assembly>

它需要与 /assembly/deployment/deploymentProvider/@codebase 类似，但需要考虑命名空间前缀。部署元素可能会导致问题，因为它不像其祖先那样位于 asmv1 命名空间中。

任何人都可以提供代码库属性的 ​​xpath 吗？

您没有向我们详细说明将在什么上下文中使用 XPath 表达式，但通常：

  1. 映射asmv1到urn:schemas-microsoft-com:asm.v1
  2. 映射asmv2到urn:schemas-microsoft-com:asm.v2

那么这个表达式会给你你想要的：

/asmv1:assembly/asmv2:deployment/asmv2:deploymentProvider/@codebase
