Code:
<?xml version="1.0" encoding="UTF-8"?>
<Students>
	<Student id="1">
		<Name>Peter</Name>
	</Student>
	<Student id="2">
		<Name>Paker</Name>
	</Student>
	<lang>
		<Student id="1">
			<Name>java</Name>
		</Student>
		<Student id="2">
			<Name>vb</Name>
		</Student>
	</lang>
</Students>
XML FILE

Code:
if (xmlhttp.readyState == 4 ) {
				xmldoc =  xmlhttp.responseXML;
				if ( xmlhttp.status == 200 ){
					students = xmldoc.getElementsByTagName("lang");
					student = students[0].childNodes;
					for (;i<student.length;i+=cnt){
						result += student[i].nodeName + "=" + student[i].firstChild.data+"<br />";
					}
					obj.innerHTML = result;
				}
			}
javascript


If I use these code, I can just get:
Student=
Student=

How can I get java and vb in the for loop? thx
