<% @ Import Namespace=""%>
<html>
<script language="C#" runat="server">
private void Page_Load(Object sender,EventArgs e)
{
    XmlTextReader objXMLReader=new XmlTextReader((""));
    string strNodeResult="";
    XmlNodeType objNodeType;
while(())
{
    objNodeType =;
    swith(objNodeType)
    {
    case :
//Read XML file header
      strNodeResult+="XML Declaration:<b>"++""++"</b><br/>";
      break;
   case :
//Read the tag
     strNodeResult+="Element:<b>"++"</b><br/>";
     break;
   case :
//Read the value
     strNodeResult+=" -Value:<b>"++"</b><br/>";
     break;
   }
//Discern whether the node has attributes
if(>0)
{  //Use loop to determine all nodes
    while()
{ //Get the label and value
     strNodeResult+=" -Attribute:<b>"++"</b> value:<b>"++"</b><br/>";
      }
   }
=strNodeResult;
}
}
