XML help..

XML help..

hi,

i am badly stuck, in need of 'SOS' help.

THE PROBLEM--

my php server sends xml document as echos--

like echo "<option>".$value."</option>"


i want to receive it on my user end using Ajax. here is my code ( i am usin CI)

url: "<?=base_url();?>Main/prova",
           global: false,
           type: "POST",
           async: false,
           dataType: "html",  // "xml doesn't work "
           data: "first_select="+ valore, //the name of the $_POST variable and its value
           success: function (xml) //'response' is the output provided by the controller method prova()
                  {
                     
                     var xmlDoc = xml.ResponseXML;
               try // Build Markers, if available
               {
                  alert(xml);
                   var markers = xmlDoc.getElementsByTagName("option") ;
                   for ( var i = 0; i < markers.length ; i++ )
                   {
                       var point = {
                           markers[i].getAttribute("lat")),
                           markers[i].getAttribute("lng")
                       };
                   }
               } catch(e) {}


above code is not working, since xmlDoc.getElementsByTagName("") is not working properly.

is it possible to handle data without .xml document, to parse xml data.
