使用 ASP.NET Grid 显示分层 xml 数据

我有以下 XML 数据。我需要以分层表格格式将它们呈现在 ASP.NET 网页上。


XML：


<Developers>

  <Region name="UK">

    <Region name="England">

      <Region name="London">

        <Data Date="01-01-2019">

          <Value name="DotNet">100</Value>

        </Data>

        <Data Date="01-01-2020">

          <Value name="DotNet">200</Value>

          <Value name="Java">300</Value>

        </Data>

      </Region>

      <Region name="Other">

        <Data Date="01-01-2019">

          <Value name="DotNet">400</Value>

        </Data>

        <Data Date="01-06-2019">

          <Value name="DotNet">500</Value>

        </Data>

      </Region>

    </Region>

    <Region name="Scotland">

      <Data Date="01-01-2019">

        <Value name="DotNet">600</Value>

      </Data>

    </Region>

  </Region>

  <Region name="France">

    <Data Date="01-06-2020">

      <Value name="DotNet">700</Value>

    </Data>

  </Region>

  <Region name="Germany">

    <Data Date="01-06-2019">

      <Value name="Java">800</Value>

    </Data>

  </Region>

</Developers>

其中 (-) 是树视图的展开/折叠控件。

是否可以使用 ASP.NET 数据网格来实现此目的？任何代码示例都会非常有用。
