Parse an XML String into an XML DOM object using javascript

Consider a XML document books.xml. The below code will parse this XML document into an XML document object or DOM.

   xmlhttp=new XMLHttpRequest();

 xmlhttp.open("GET","books.xml",false);
xmlhttp.send();
xmlDoc=xmlhttp.responseXML;

Now, Consider the case when you have an XML String on a client side and you want to convert it into a DOM object. This also can be achieved using javascript by using the below code snippet.

txt="<Customer>";
txt=txt+"<title>JavaGenious</title>";
txt=txt+"<author>www.javagenious.com</author>";
txt=txt+"<year>2007</year>";
txt=txt+"</Customer>";

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