msbuild - msbuild数组迭代

Question

<ItemGroup>
    <!-- Unit Test Projects-->
    <MyGroup Include="Hello.xml" />
    <MyGroup Include="GoodBye.xml" />     
</ItemGroup>

我如何做遍历此列表并执行某些操作的任务？

<XmlPeek XmlInputPath="%(MyGroup.Identity)"
         Query="/results">
    <Output TaskParameter="Result"
            ItemName="myResult" />
</XmlPeek>

如果myresult里面有特定文本，我想发出一条错误消息。但是对于我一生，我无法弄清楚如何在Msbuild中遍历数组……任何人都知道如何实现这一点？

您可以在内部目标上使用batching，例如：

<ItemGroup>
  <!-- Unit Test Projects-->
  <MyGroup Include="Hello.xml" />
  <MyGroup Include="GoodBye.xml" />     
</ItemGroup>

<Target Name="CheckAllXmlFile">
  <!-- Call CheckOneXmlFile foreach file in MyGroup -->
  <MSBuild Projects="$(MSBuildProjectFile)"
           Properties="CurrentXmlFile=%(MyGroup.Identity)"
           Targets="CheckOneXmlFile">
  </MSBuild>
</Target>

<!-- This target checks the current analyzed file $(CurrentXmlFile) -->
<Target Name="CheckOneXmlFile">
  <XmlPeek XmlInputPath="$(CurrentXmlFile)"
           Query="/results/text()">
    <Output TaskParameter="Result" ItemName="myResult" />
  </XmlPeek>

  <!-- Throw an error message if Result has a certain text : ERROR -->
  <Error Condition="'$(Result)' == 'ERROR'"
         Text="Error with results $(Result)"/> 
</Target>
