我正在尝试将转换应用于 HTML 文件。转换适用于 div 和 span，但只要我插入 P 标签，它就会失败。

我正在转换的 HTML 文件是：

<!DOCTYPE html>
<html>
  <head>
    <title>STREAM Interactive - UAT</title>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

  </head>
    <body>
          <p>my para</p>
    </body>
</html>

转换文件非常简单：

<html xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
   <head>
     <title xdt:Transform="Replace">TITLEHEADINGHERE</title>
   </head>  

</html>

用于进行转换的项目文件是：

<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<UsingTask TaskName="TransformXml" AssemblyFile="C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v10.0\Web\Microsoft.Web.Publishing.Tasks.Dll"/>

    <PropertyGroup>
        <SourceFile>web.config</SourceFile>
        <TransformFile>web.debug.config</TransformFile>
        <OutputFile>final.config</OutputFile>
    </PropertyGroup>

    <Target Name="GenerateConfigs">
        <Message Text="Beginning Transformation." />
        <Message Text="$(SourceFile)" />
        <TransformXml Source="$(SourceFile)" Transform="$(TransformFile)" Destination="$(OutputFile)" />
        <Message Text="Completed Transformation." />
    </Target>

</Project>

使用的命令是：

C:\Windows\Microsoft.NET\Framework64\v4.0.30319\msbuild.exe D:\SAM\SAMSite\bin\msbuild-transform-Template.xml /p:SourceFile="C:\temp\buildTest\BlueZone\2.3.10.5\PublishedClickOnce\index.html" /p:TransformFile="D:\SAM\SAMSite\bin\TransformTemplates\clickonce.index.transform.temp" /p:OutputFile="C:\temp\buildTest\BlueZone\2.3.10.5\PublishedClickOnce\index.html.temp"

我得到的输出/错误是：

HTML 已被尽可能地精简，以前那里有 div 和 span。有趣的是，如果我给 P 标签一个类，它就可以工作。

我不知道为什么会这样。

编辑

根据@Kieren 的建议，我尝试直接使用 TransformXml 运行。我收到一个新错误：

Data at the root level is invalid. Line 1, position 1.

根据我提交的错误报告，此问题现已修复。假设它将包含在 MsBuild 的下一个版本中，（不知道什么时候会）：
