<user>
   <name>yongkang</name>
   <password>zhang</password>
</user>
</person>
修改xml的asp如下：
<%
var username=Request("username");
var password=Request("password");
var objDom = Server.CreateObject("MicroSoft.XMLDOM");
objDom.async = false;
objDom.load (Server.MapPath("user.xml"));
var rootNode = objDom.documentElement
var userNode = objDom.getElementsByTagName("user");
     for(var i=0; i < userNode.length; i++ )
      {
       var nameNode = userNode.item(i).firstChild;
       var userNameR = nameNode.firstChild.nodeValue;
       var passwordNode = userNode.item(i).lastChild;
       var userPasswordR = passwordNode.firstChild.nodeValue;
       if (username == userNameR&&password == userPasswordR)
           {
            rootNode.removeChild(i);-----------------------------------错误
            objDom.save (server.mappath("user.xml"));
            Response.Redirect("showdata2.html");
           }
          
       }
      
%>
浏览器说这一行有错（已经标注出来），各位大虾能帮我改正一下么，我的目的是想删除一个user节点

查一下API，很容易就搞定了。
