如何根据文件名部分过滤MsBuild中的ItemGroup? [英] How to filter ItemGroup in MsBuild based on filename part?

问题描述

我有一个ItemGroup，其中包含一些文件(而且我无法控制此列表的生成方式):

I have an ItemGroup that contains some files (And I have no control on how this list is generated):

<ItemGroup>
    <AllFiles Include="Assembly1.dll;Assembly1.Tests.dll"/>
    <AllFiles Include="Assembly2.dll;Assembly2.Tests.dll"/>
    ...
</ItemGroup>

我想创建第二个ItemGroup(基于第一个)，仅用于匹配****.Tests.dll的文件名.即FilteredFiles应为:Assembly1.Tests.dll，Assembly2.Tests.dll，...

And I would like to create a second ItemGroup (based on the first one) holding only for filenames matching ****.Tests.dll. That is FilteredFiles should be: Assembly1.Tests.dll, Assembly2.Tests.dll, ...

到目前为止，我已经尝试过:

So far I tried:

<ItemGroup>
    <FilteredFiles Include="@(AllFiles)" Condition="$([System.Text.RegularExpressions.Regex]::IsMatch(%(Filename), '\.Tests\.dll'))"/>
</ItemGroup>

但是它似乎不起作用.

But it doesn't seem to work.

PS:我也想进行不区分大小写的匹配，但这是另一个问题.

PS: I would also like for non case sensitive matches but that's another issue.

推荐答案

您需要使用％而不是@使用项目批处理.这将逐项处理项目，而不是同时包含所有项目.您的条件正确，我认为您在其他地方找到了.

You need to use item batching using the % instead of the @. This will work on the items one by one instead of including them all at the same time. You had the condition right, which I assume you found somewhere else.

<ItemGroup>
  <FilteredFiles Include="%(AllFiles.Identity)" Condition="$([System.Text.RegularExpressions.Regex]::IsMatch(%(Filename), '\.Tests\.dll'))"/>
</ItemGroup>
