Consider the following JavaScript code that conducts XML parsing

text = "<bookstore><book>" + "<title>Everyday Italian</title>" +
   "<author>Giada De Laurentiis</author>" + "<year>2005</year>" +
   "</book></bookstore>";

parser = new DOMParser();
xmlDoc = parser.parseFromString(text,"text/xml");

var a = xmlDoc.getElementsByTagName("year")[0].nodeName;
