我的问题是,是否存在xdt：Transform将清除空元素.我在这里找不到任何东西.

这是我的例子.

我当前的Web.config.install.xdt看起来像这样

<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
  <system.web>
    <compilation xdt:Transform="InsertIfMissing">
      <assemblies xdt:Transform="InsertIfMissing">
        <add xdt:Transform="InsertIfMissing" xdt:Locator="Match(assembly)" assembly="MyAssembly,Version=4.5.4.0,Culture=neutral,PublicKeyToken=asdfasdfasdfasdf" />
      </assemblies>
    </compilation>
  </system.web>
</configuration>

我的卸载看起来像这样

<?xml version="1.0"?>
<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
  <system.web>
    <compilation>
      <assemblies>
        <add xdt:Transform="Remove" xdt:Locator="Match(assembly)" assembly="MyAssembly,PublicKeyToken=asdfasdfasdfasdf" />
      </assemblies>
    </compilation>
  </system.web>
</configuration>

这是我的web.config之前(简化)

<system.web>
    <authentication mode="None" />
    <compilation debug="true" targetFramework="4.5" />
    <httpRuntime targetFramework="4.5" />
  </system.web>

这是install.xtd之后的web.config

<system.web>
    <authentication mode="None" />
    <compilation debug="true" targetFramework="4.5">
      <assemblies>
        <add assembly="MyAssembly,PublicKeyToken=asdfasdfasdfasdf" />
      </assemblies>
    </compilation>
    <httpRuntime targetFramework="4.5" />
  </system.web>

这是卸载后的web.config

<system.web>
    <authentication mode="None" />
    <compilation debug="true" targetFramework="4.5">
      <assemblies>
      </assemblies>
    </compilation>
    <httpRuntime targetFramework="4.5" />
  </system.web>

反正有没有摆脱标签？
