i want the percentage, result and exam_name for all the attempts by a name in javascript.

here is my javascript i'm using and i'm struck up fetching the child node value.

i'm selecting the names and for a selected name i want the complete score tag to be displayed. please help me in getting this. the javascript im using is :

for ( var i = 0; i < xmlDoc.getElementsByTagName("name").length; i++) {
        uname = xmlDoc.getElementsByTagName("name")[i].childNodes[0].nodeValue;
        alert(uname);

        if (selectedValue == uname) {

             for ( var j = 0; j < xmlDoc.getElementsByTagName("score")[i].childNodes.length; j++) {
                var attempt = xmlDoc.getElementsByTagName("score")[i].childNodes[j].nodeValue;
                alert("in loop");
                alert(attempt);
            } 
            alert("name is equal");
            break;
        }
    }

For given name retrieve it's score :

   function getScoreByName(nameparam, xml){
      var nameList = xml.getElementsByTagName('name');

      for(var i=0; i<nameList.length; i++){
        if(nameparam === nameList[i].firstChild.nodeValue){

           //parentNode = <emp>
           //lastChild = <score>
           handleAttempts(nameList[i].parentNode.lastChild.childNodes);

           //print name here
        } 
      }
    }

    function handleAttempts(attemptList){
      var percentage; 
      var result; 
      var examName; 

      for(var i=0; i<attemptList.length; i++){
        percentage=attemptList[i].childNodes[0].firstChild.nodeValue;
        result=attemptList[i].childNodes[1].firstChild.nodeValue;
        examName=attemptList[i].childNodes[2].firstChild.nodeValue;  

        //print attempt here
      }
    }

Use jQuery , and its selectors e.g

elements = $(yourXml).find('name');
$.each(elements, function(key, elem) {
    $(elem).find("score");
    //do whatever you want with individual score nodes
} );
