我页面传递一个ID过来 我想判断下如果ID等于XML中的ID，那么删除这个LIST节点
我试着写了下 都没删成功，希望各位牛人能帮下小弟。  
  string id =Request.QueryString["ID"].ToString();
                string xmlPath = Server.MapPath("/act/info.xml");
                XmlDocument xml = new XmlDocument();
                xml.Load(xmlPath);
                XmlNodeList xmlNode = xml.DocumentElement.ChildNodes;
                for (int i = 0; i < xmlNode.Count; i++)
                {
                    if (xmlNode[i].InnerText.Equals(id))
                    {
                        xml.RemoveChild(xmlNode[i]);
                    }
                }

Answer 1

 public static void Delete(string path, string node, string attribute)
        {
            try
            {
                XmlDocument doc = new XmlDocument();
                doc.Load(path);
                XmlNode xn = doc.SelectSingleNode(node);
                XmlElement xe = (XmlElement)xn;
                if (attribute.Equals(""))
                    xn.ParentNode.RemoveChild(xn);
                else
                    xe.RemoveAttribute(attribute);
                doc.Save(path);
            }
            catch { }
        }

子夜  我这个NODE应该怎么写呢？

Answer 4

随手写的，比较粗糙，见谅string id = Request.QueryString["ID"].ToString();
string xmlPath = Server.MapPath("/act/info.xml");
XmlDocument xml = new XmlDocument();
xml.Load(xmlPath);
string xpath = "/ROOT/list[id=" + id + "]";
string par = xml.SelectSingleNode(xpath).ParentNode.Name;
xml.SelectSingleNode(par).RemoveChild(xml.SelectSingleNode(xpath));
xml.Save(xmlPath);
xml = null;

Answer 5

        string id="1";
        XmlDocument xml = new XmlDocument();
        xml.Load(Server.MapPath("XMLFile2.xml"));
        XmlNodeList node = xml.SelectNodes("/ROOT/list/id");
        foreach (XmlNode n in node)
        {
            if (n.InnerText == id)
                n.ParentNode.ParentNode.RemoveChild(n.ParentNode);
        }
        xml.Save(Server.MapPath("XMLFile2.xml"));
