Try this:

var xpath = require('xpath'), 
    dom = require('xmldom').DOMParser
    xml= ".. xml string .."

var doc = new dom().parseFromString(xml)
var nodes = xpath.select("//student", doc)
nodes.forEach(function(node){
    var courses = node.getElementsByTagName('coursename')
    for(var i=0;i< courses.length;i++){
        console.log(node.firstChild.firstChild.nodeValue,courses[i].firstChild.nodeValue)
    }
})
