如何使用MSBuild创建XML文件？

我想在MSBuild任务中创建一个XML文件

我有一个文件列表：

<CreateItem Include="$(TestsAssembliesOutputDir)\Emidee.*.Tests.dll">
  <Output ItemName="TestsAssemblies" TaskParameter="Include" />
</CreateItem>

我想创建一个如下所示的XML：

<?xml version="1.0" encoding="utf-8"?>
<xunit>
  <assemblies>
    <assembly filename="PATH OF FILE #1" shadow-copy="true" />
    <assembly filename="PATH OF FILE #2" shadow-copy="true" />
  </assemblies>
</xunit>

我怎样才能做到这一点

提前谢谢

迈克又快又脏

<Target Name="CreateXml">
  <ItemGroup>
    <TestAssembly Include="$(TestsAssembliesOutputDir)\Emidee.*.Tests.dll" />
    <Line Include="line01"><Text>&lt;xunit&gt;</Text></Line>
    <Line Include="line02"><Text>&lt;assemblies&gt;</Text></Line>
    <Line Include="line03"><Text>&lt;assembly filename=&quot;%(TestAssembly.Identity)&quot; shadow-copy=&quot;true&quot; /&gt;</Text></Line>
    <Line Include="line04"><Text>&lt;/assemblies&gt;</Text></Line>
    <Line Include="line05"><Text>&lt;/xunit&gt;</Text></Line>
    <LineText Include="%(Line.Text)" />
  </ItemGroup>
  <WriteLinesToFile
     File="out.xml"
     Lines="@(LineText)"
     Overwrite="true"
     />
</Target>

有。

一个选项是使用内联任务。这允许您编写任意C#代码来生成Xml，这可能比其他解决方案更容易（或更难）。下面是一个例子，我用它在我的构建中拼凑出一个NuGet-nuspec文件

                var root = Path.GetFullPath(BaseFolder);    

                using (var w = XmlWriter.Create(OutputFile.ItemSpec)) {
                    var ns = "http://schemas.microsoft.com/packaging/2010/07/nuspec.xsd";
                    w.WriteStartElement("package", ns);

                    w.WriteStartElement("metadata");

                    w.WriteStartElement("id");
                    w.WriteValue(ProjectName);
                    w.WriteEndElement();

                    w.WriteValue("Test");
                    w.WriteEndElement();

                    w.WriteEndElement();


                    w.WriteStartElement("files");

                    foreach(var file in Files) {
                        w.WriteStartElement("file");
                        var inFile = file.ItemSpec;
                        inFile = inFile.Replace(root, "");
                        w.WriteAttributeString("src", inFile);
                        w.WriteAttributeString("target", inFile);
                        w.WriteEndElement();
                    }

                    w.WriteEndElement();

                    w.WriteEndElement();
                }
