Get XML document content asynchronously with ASP.net ajax

ajax|asp.net|xml| Asynchronous

Ajax is intended to be used to get XML content asynchronously to achieve a web-without-refresh effect
asp.net Ajax has encapsulated the underlying content
The implementation is far more convenient than writing XMLHTTP, at least the browser compatibility is much stronger
Here's a www.asp.net example of how to use a Microsoft Ajax library to get an XML document simple and asynchronous

//return XML Web request
Function onsucceededxml (executor, EventArgs)
... {
    if (executor.get_responseavailable ())
    ... {
      
        if (document.all)
            Resultelementid.innertext + = Executor.get_xml ( ). xml;
        Else
            //Firefox
            Resultelementid.textcontent + = "First node[node]:" +
                 executor.get_xml (). Documentelement.nodename;

   }
    else
    ... {
        if (executor.get_timedout ())
             alert ("timeout");
        Else
             if (executor.get_aborted ())
                 alert ("failure");
   }
}
Function GetXml ()
... {
   //Create WebRequest object
    wrequest =  new Sys.Net.WebRequest ();

Set up request files
Wrequest.set_url ("Index.xml");

Set the request handler.
Wrequest.add_completed (Onsucceededxml);

Clear the results area.
if (document.all)
Resultelementid.innertext = "";
Else
Firefox
Resultelementid.textcontent = "";

Invoke the WEB request.
Wrequest.invoke ();
}
