使用 PowerShell Core 7.4.6。

鉴于文件/path/to/file.csproj

<Project Sdk="Microsoft.NET.Sdk">
    <ItemGroup>
        <ProjectReference Include="Path\To\Something.csproj" />
    </ItemGroup>
</Project>

我期望以下代码片段ProjectReference使用内置的 XPathends-with函数从该文件中选择节点

select-xml -path "/path/to/file.csproj" `
    -xpath "/Project/ItemGroup/ProjectReference[ends-with(@Include, 'Something.csproj')]"

但相反，它会产生错误

Select-Xml: Namespace Manager or XsltContext needed. This query has a prefix, variable, or user-defined function.

如果我尝试使用 XPath 函数命名空间明确地确定其范围

select-xml -path "/path/to/file.csproj" `
    -xpath "/Project/ItemGroup/ProjectReference[fn:ends-with(@Include, 'Something.csproj')]" `
    -namespace @{ "fn" = "http://www.w3.org/2005/xpath-functions" }

我收到了另一个错误

Select-Xml: XsltContext is needed for this query because of an unknown function.

我错过了什么？文档Select-Xml提到对调用 XPath 函数没有任何限制，因此我认为它们是本机支持的。
