i'm getting duplicate results xml file. want delete excess ones having trouble achieving using splice , indexof. can point me in right direction??

var xmlloader:urlloader = new urlloader(); var xmlreq:urlrequest = new urlrequest("data.xml");  xmlloader.load(xmlreq);   var background:bkg;  var textvar:textfield = new textfield;          xmlloader.addeventlistener(event.complete, convertdata);  function convertdata(event:event){       var xmlinfo:xml = new xml(event.target.data);        //trace(xmlinfo);       var list:xmllist = xmlinfo.profile.photography;      var totalimage:number = list.length();      trace("length " + totalimage);      enterbtn.addeventlistener(mouseevent.click, entersite);      function entersite(event:mouseevent){         (var i:int =0; i<totalimage; i++){             trace(xmlinfo.profile.photography[i]);              background = new bkg();             background.y = i*40;             background.x =80;             addchild(background);              textvar = new textfield();             textvar.text = list[i];                 background.addchild(textvar);         }      }    }

xml file

        <profile>             <first_name>ann</first_name>             <last_name> lee</last_name>             <photography>sport</photography>             <photography>landscape</photography>             <photography>still life</photography>                        <image>img1.jpg</image>          </profile>          <profile>                <first_name>john</first_name>             <last_name> thomas</last_name>             <photography>wildlife</photography>             <photography>landscape</photography>             <image>img2.jpg</image>         </profile>

here example on how you'd like:

using test xml:

var xml:xml =   <data>                 <profile>                     <first_name>ann</first_name>                     <last_name> lee</last_name>                     <photography>sport</photography>                     <photography>landscape</photography>                     <photography>still life</photography>                                <image>img1.jpg</image>                 </profile>;                 <profile>                        <first_name>john</first_name>                     <last_name> thomas</last_name>                     <photography>wildlife</photography>                     <photography>landscape</photography>                     <image>img2.jpg</image>                 </profile></data>; 
//create array, , popluate xml nodes var list:array = new array(); xml.profile.photography.(list.push(tostring()));  // ^ converts xmllist array running method in brackets on each item in xmllist  //sort duplicate values grouped list.sort();  trace(list); //this traces out full list  //now iterate array/vector var i:int = 0; while(i < list.length) {      //while next item matches current, splice out     while(i < list.length+1 && list[i] == list[i+1]) {         list.splice(i, 1);     }     i++; }  trace(list); //this list no duplicates
