使用LINQ to XML查询子节点的内部xml

Question

让我们说我有这个xml:

<items>
  <item name="thumb">
    <downloadStream>test1</downloadStream>
    <downloadStream>test2</downloadStream>
    <downloadStream>test3</downloadStream>
  </item>
  <item name="photo">
    <downloadStream>test5</downloadStream>
    <downloadStream>test6</downloadStream>
    <downloadStream>test7</downloadStream>
  </item>
</items>

我正在尝试编写一个返回我的LINQ to XML语句:

{"test5","test6","test7"}

换句话说,它返回每个"downloadStream"节点的内部xml,其中父节点具有属性(name ="photo").

我该怎么做呢？

像这样的东西:

            var rootElement = XElement.Parse(xml);
            var results = rootElement.
               .Elements()
               .Where( e => e.Attribute("name") == "photo" )
               .SelectMany( e => e.Elements )
               .Select( e => e.Value );
