How an asp.net website return an xml document

Generate the xml, write it to the response output stream and set the response content type to "text/xml" or "application/xml".

Hi,

I have achieved the same solution using the code mentioned below.

under page load write below code.

protected void Page_Load(object sender, EventArgs e)
    {



        Response.ContentType = "text/xml";
        Response.Charset = "utf-8";


            GenerateXML("XML_Output", Response.OutputStream);

        Response.End();


    }

and for GenerateXML method write below code

public void GenerateXML(string Format, Stream stream)
    {
        XmlWriterSettings settings = new XmlWriterSettings();


        settings.Indent = true;
        using (XmlWriter writer = XmlWriter.Create(stream, settings))
        {
            writer.WriteStartDocument();
            writer.WriteStartElement("root");

            //Get values from the database into a datatable


            foreach (DataRow dr in extracteddatatable.Rows)
            {
                // Repeat this code:
                string strDes = "<![CDATA[Class : <b>"+ "]]>";

                writer.WriteStartElement("rootelement");

                writer.WriteElementString("RLS ", dr["extractedfield"].ToString());



                //end location subroot
                writer.WriteEndElement();


            }




            writer.WriteEndElement();
            writer.WriteEndDocument();
        }
    }

and don't forget to add below mentioned namespaces :)

using System.Xml.Xsl;
using System.Xml.Schema;
using System.Data.SqlClient;
using System.Text;
using System.IO;
using System.Xml.Serialization;
using System.Xml;

please let me know if any problem

I think that you need to do it with Ajax. When making a server request in Ajax, the data returned can be in either plain text/html, or an XML document instead. The later is technically just a text file as well, but with some special instructions, Ajax can retrieve that well formed XML text file and return it back to you as a XML object. This enables the XML data to be easily parsed using standard DOM methods.

Here's a simple XML document. It is showed in RSS format I'll be using for illustration (lets name it "results.xml"):

<rss version="0.91">
<channel>
<title>domain.com</title>
<link>http://www.domain.com</link>

The below shows retrieving this XML document and outputing the headlines ("title" elements) of each entry:

<script type="text/javascript">

function ajaxRequest(){
 var activexmodes=["Msxml2.XMLHTTP", "Microsoft.XMLHTTP"] //activeX versions to check for in IE
 if (window.ActiveXObject){ //Test for support for ActiveXObject in IE first (as XMLHttpRequest in IE7 is broken)
  for (var i=0; i<activexmodes.length;>   try{
    return new ActiveXObject(activexmodes[i])
   }
   catch(e){
    //suppress error
   }
  }
 }
 else if (window.XMLHttpRequest) // if Mozilla, Safari etc
  return new XMLHttpRequest()
 else
  return false
}

var mygetrequest=new ajaxRequest()
if (mygetrequest.overrideMimeType)
 mygetrequest.overrideMimeType('text/xml')
mygetrequest.onreadystatechange=function(){
 if (mygetrequest.readyState==4){
  if (mygetrequest.status==200 || window.location.href.indexOf("http")==-1){
   var xmldata=mygetrequest.responseXML //retrieve result as an XML object
   var rssentries=xmldata.getElementsByTagName("item")
   var output='<ul>'
   for (var i=0; i<rssentries.length;>    output+='<li>'
    output+='<a href="'+rssentries[i].getElementsByTagName('link')[0].firstChild.nodeValue+'">'
    output+=rssentries[i].getElementsByTagName('title')[0].firstChild.nodeValue+'</a>'
    output+='</li>'
   }
   output+='</ul>'
   document.getElementById("result").innerHTML=output
  }
  else{
   alert("An error has occured making the request")
  }
 }
}

mygetrequest.open("GET", "results.xml", true)
mygetrequest.send(null)

</script>

I hope that it will be useful
