如何读取这样的XML?
<1>
<a> 3 </a>
<f> g </f>
<r> f </r>
<k> l </k>
</1>
<2>
<a> 3t </a>
<f> gg </f>
<r> fe </r>
<k> ls </k>
</2>
<3>
<a> 3v </a>
<f> ge </f>
<r> fdd </r>
<k> lhht </k>
</3>
<4>
<a> 123 </a>
<f> dd </f>
<r> ff </r>
<k> lb </k>
</4>
我想当我查询进来的ID=?的时候进行查询!
之后读取这个接点下的所有的东西!
怎么办?在线等急!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

private void previous_Click(object sender, EventArgs e)
{
XmlDocument xmlDoc = new XmlDocument();
string strPath = "root/itemData/cell "; //查询路径
XmlNodeList nodeList = null;
string strItem = " "; //item值
string strKey = " "; //key值
string strValue = " "; //value值
try
{
xmlDoc.Load( "e:\\新建 文本文档 (2).xml ");
//获取所有的itemData项
nodeList = xmlDoc.SelectNodes(strPath);
//遍历所有节点
foreach (XmlNode node in nodeList)
{
strItem = node.Attributes[ "item "].InnerText;
//遍历所有字节点
foreach (XmlNode subNode in node.ChildNodes)
{
strKey=subNode.Attributes[ "key "].InnerText;
strValue = subNode.Attributes[ "value "].InnerText;
//strItem,strKey,strValue值都获取了,剩下就是对数据库操作，我就不再多说
}
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}

}
}
catch (Exception e)

Console.WriteLine(e.ToString());
}
finally
{

Console.Read();

=====运行结果
name:a value:3t
name:f value:gg
name:r value:fe
name:k value:ls
