xml文档如下:
<?xml version="1.0" encoding="UTF-8"?>
<students>
    <student>
         <name>zhangfayu</name>
         <pwd>21</pwd>
         <id>123</id>
   </student>
 <student>
        <name>lichao</name>
        <pwd>23</pwd>
        <id>234</id>
   </student>
</students>
删除代码(根据给定的id查找相应的项并删除)
XmlDocument Doc =new XmlDocument();
        XmlNodeList xnl;
            Doc.Load(Application.StartupPath + "[url=file://\\students.xml]\\students.xml[/url]");
            xnl = Doc.SelectSingleNode("students").ChildNodes;
            for (int i = 0; i < xnl.Count; i++)
            {
                if (xnl.Item(i).ChildNodes.Item(1).InnerText == cmbID.SelectedItem.ToString())
                {
                   xnl.Item(i).RemoveChild(xnl.Item(i));
                     
                }
            }
红色部分为删除代码
但是执行之后xml将变为
<?xml version="1.0" encoding="UTF-8"?>
<students>
    <student>
    </student>
<student>
        <name>lichao</name>
        <pwd>23</pwd>
        <id>234</id>
   </student>
</students>
只删除了信息 节点却还在
问怎么才能够删除啊?
谢谢

主要是我查找的时候是 根据<student>下的<id>标签进行的
xnl.Item(i).Removeall(xnl.Item(i)) 上面删除代码是这
还是不行啊

返回父节点
将会变成
<studnets>
中间全被删除了
</students>

谢谢大家了　　
搞定　　了

回LS
假设xml.Item(i)为你要删除student的pwd
xnl.Item(i).RemoveChild(pwd);
