C# 操作xml移动节点到指定位置.............................................新手求解,在线等

XML code

<?xml version="1.0" encoding="utf-8"?><root>  <left>    <div1></div1>    <div2></div2>    <div3></div3>  </left>  <center>    <div4></div4>    <div5></div5>    <div6></div6>  </center>  <right>    <div7></div7>    <div8></div8>    <div9></div9>  </right></root>

C# code

/// <summary>        /// 将节点下的子节点移动至其他节点下        /// <root>        /// <test>        /// <test2></test2>        /// </test>        /// <test1>        /// </test1>        /// </root>        /// 将test2移动到test1下        /// </summary>        /// <param name="xmlPath">xxx.xml</param>        /// <param name="oldNode">root/test</param>        /// <param name="newNode">root/test1</param>        /// <param name="node">test2</param>        public static void XmlMoveNode(string xmlPath, string oldNode, string newNode, string node)        {            XmlDocument xDoc = new XmlDocument();            //加载app.config            xDoc.Load(xmlPath);            XmlNode xNode = xDoc.SelectSingleNode(oldNode);            XmlNode targetNode = xNode.SelectSingleNode(node); ;            if (targetNode == null)            {                throw new Exception("Node not found:" + node);            }            else            {                xNode.RemoveChild(targetNode);            }            XmlNode yNode = xDoc.SelectSingleNode(newNode);            yNode.AppendChild(targetNode);            xDoc.Save(xmlPath);        }

XmlMoveNode(xxx.xml,"root/left","root/right","div1");
这个方法只实现了将div1子节点从left移动到right,放在right最后一位。
我想修改XmlMoveNode(xxx.xml,"root/left","root/right","div1",2);
实现将div1子节点从left移动到right的第二个
结果如下：

XML code

<?xml version="1.0" encoding="utf-8"?><root>  <left>    <div2></div2>    <div3></div3>  </left>  <center>    <div4></div4>    <div5></div5>    <div6></div6>  </center>  <right>    <div7></div7>    <div1></div1>    <div8></div8>    <div9></div9>  </right></root>

我该怎么实现，最好给个XmlMoveNode()的源码。先谢过了。

[解决办法]

C# code

        //XmlMoveNode("..\\..\\test.xml", "//root/left", "//root/right", "//div1",2);        public static void XmlMoveNode(string xmlPath, string oldNode, string newNode, string node, int index)        {            XmlDocument xDoc = new XmlDocument();            //加载xml文件            xDoc.Load(xmlPath);            //获取原来所在节点            XmlNode xNode = xDoc.SelectSingleNode(oldNode);            //获取要移动的节点            XmlNode targetNode = xNode.SelectSingleNode(node); ;            if (targetNode == null)            {                throw new Exception("Node not found:" + node);            }            else            {                //在原位置删掉要移动的节点                xNode.RemoveChild(targetNode);            }            //获取需要移动到的目标节点            XmlNode yNode = xDoc.SelectSingleNode(newNode);            //判断目标节点是否有足够的子节点,有则按顺序插入，没有则添加。            if (yNode.HasChildNodes && yNode.ChildNodes.Count > index - 1)            {                //在目标节点指定的位置插入要移动的节点                yNode.InsertAfter(targetNode, yNode.ChildNodes[index - 2]);            }            else            {                yNode.AppendChild(targetNode);            }            xDoc.Save(xmlPath);        }
