Asp.net 使用XMLNodeList的嵌套中继器

我被一个问题困住了。我想我可能已经接近解决方案了，但似乎无法实现。我有一个XMLDoc，它从一个存储过程加载到一个数据集中，然后从中提取xml（我想我不能更改这部分的任何内容）。XML如下所示：

<data>
  <datanode>
    <name>11</name>
    <group>G1</group>
    <value>val1</value>
  </datanode>
  <datanode>
    <name>12</name>
    <group>G1</group>
    <value>val2</value>
  </datanode>  
  <datanode>
<name>21</name>
<group>G2</group>
<value>val1</value>
  </datanode>
  <datanode>
<name>22</name>
<group>G2</group>
<value>val2</value>
  </datanode>
  <datanode>
<name>23</name>
<group>G2</group>
<value>val3</value>
  </datanode>  
  <datanode>
<name>31</name>
<group>G3</group>
<value>val1</value>
  </datanode>
  <datanode>
<name>32</name>
<group>G3</group>
<value>val2</value>
  </datanode>
  <datanode>
<name>33</name>
<group>G3</group>
<value>val3</value>
  </datanode>
  <datanode>
<name>34</name>
<group>G3</group>
<value>val4</value>
  </datanode>
</data>

到目前为止，我所拥有的： Default.aspx：

    <asp:Repeater ID="Repeater1" runat="server">

    <ItemTemplate>
        <p>                
            COUNT: <asp:Literal runat="server" ID="Literal3" Text='<%# XPath("count(group)") %>' />                
            <br />Text: <asp:Literal runat="server" ID="Literal4" Text='<%# XPath("text()") %>' />
            <br />Group: <asp:Literal runat="server" ID="Literal2" Text='<%# XPath("group") %>' />
            <br />ID: <asp:Literal runat="server" ID="displayname" Text='<%# XPath("name") %>' />
            <br />VAL: <asp:Literal runat="server" ID="Literal1" Text='<%# XPath("value") %>' />
         </p>            

    </ItemTemplate>

    </asp:Repeater>

我可以让它们一个接一个地显示每个数据节点，但我不知道如何嵌套中继器并进行分组。我对XPath和Repeater还不太熟悉，我认为我的知识一定有一些差距，只是无法连接点（除非我完全走错了路）

谢谢

好的，在进一步试验后找到了我的解决方案：

                             - <%# XPath("count(..//box_item[manifest_number=" + CurrentManifestNumber + "])")%> Box(s)
