MSBuild 迭代带标签的 PropertyGroup 中的属性并检索名称和值

Question

有没有办法迭代 MSBuild 文件的属性，访问特定 <PropertyGroup> 内每个属性的名称和值？也许是这样的:

<Project ToolsVersion="4.0" DefaultTargets="test" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">

  <PropertyGroup Label="testPropertyGroup">
    <Property1>Value1</Property1>
    <Property2>Value2</Property2>
  </PropertyGroup>

  <Target Name="prop">
   <Message Text="Name=%(testPropertyGroup.Name)"/>
   <Message Text="Value=%(testPropertyGroup.Value)"/>
  </Target>

</Project>

如果您使用具有多个子节点的 ItemGroup，则它可以工作:

<ItemGroup>
  <ApplicationLanguages Include="zh-chs">
    <Name>Chinese.Simplified</Name>
    <IsAppLanguage>true</IsAppLanguage>
  </ApplicationLanguages>
  <ApplicationLanguages Include="zh-cht">
    <Name>Chinese.Traditional</Name>
    <IsAppLanguage>false</IsAppLanguage>
  </ApplicationLanguages>
  <ApplicationLanguages Include="fr">
    <Name>French</Name>
    <IsAppLanguage>true</IsAppLanguage>
  </ApplicationLanguages>
  <ApplicationLanguages Include="de">
    <Name>German</Name>
    <IsAppLanguage>true</IsAppLanguage>
  </ApplicationLanguages>
  <ApplicationLanguages Include="es">
    <Name>Spanish</Name>
    <IsAppLanguage>true</IsAppLanguage>
  </ApplicationLanguages>
</ItemGroup>
<Target Name="PrintValues" Outputs="%(ApplicationLanguages.Identity)">
  <Message Text="Identity: %(ApplicationLanguages.Identity)" Importance="high" />
  <Message Text="Name:     %(ApplicationLanguages.Name)" Importance="high" />
  <Message Text="IsValid:  %(ApplicationLanguages.IsAppLanguage)" Importance="high" />
</Target>
