高分求助：请高手进，XML读取时显示问题！

问题倒是不难
帮楼主写了一个,是采用递归的方式.
不过还是建议楼主在节点当中加上一个parent属性,或是深度属性,那样读取和解析起来更有效率.<%@ Page Language="C#" %>

  1.   

    但是西门大官人，您看见我那XML文件没，我那可是分三级的XML文件啊！
      

  2.   

    上边我的是普通取xml的代码 你说的分三级的 我没试过  
    如果用的话 把路径改了就可以了

    <root> 这个xml文件我如果想修改该怎么办呢？因为我这样修改的话：
    XmlNodeList nodeList = xmlDoc.SelectSingleNode("root").ChildNodes;
            foreach (XmlNode xn in nodeList)//遍历所有子节点
            {
                XmlElement xe = (XmlElement)xn;//将子节点类型转换为XmlElement类型
                if (xe.GetAttribute("code") == Cid)
                {
                    xe.SetAttribute("code", txtCode.Text);
                    xe.SetAttribute("name", txtName.Text);
                    break;
                }
            }
    只能找到第一级结点，子节点和子节点的子节点确找不到！
    请问该怎么办！？
