javascript - document.documentElement function does not display proper result -

i trying parse xml file using java-script. according tutorial read found root element, have use document.documentelement.

i use syntax when tried display returned value syntax, browser displays [object htmlhtmlelement].

my question is: (1) why getting [object htmlhtmlelement] displayed in web browser. (2) according below posted xml-file, should expect output after usingrootelement = document.documentelement;

please find below code used(javascript) , xml file.

javascript

function findwriter()  {         var schriftstellerknoten, spracheknoten;         var fuellerknoten, dichtungknoten, anzeige, rootelement;      rootelement = document.documentelement;     document.write(rootelement);          } 

xml file:

<?xml version="1.0" ?> <schriftsteller>    <englischsprache>       <dichtung>           <fueller>         <name>jane austin</name>             <name>rex stout</name>             <name>dashiell hammett</name>          </fueller>   </dichtung>    </englischsprache> </schriftsteller> 

document.documentelement root html tag of page in javascript present.

to fetch , display xml content, must access xml document , use load xml file following:

function findwriter()  {     var schriftstellerknoten, spracheknoten;     var fuellerknoten, dichtungknoten, anzeige, rootelement;    if (window.xmlhttprequest){     xhttp=new xmlhttprequest(); //for non ie browsers   }   else { // ie 5/6      xhttp=new activexobject("microsoft.xmlhttp");   }   xhttp.open("get","test.xml",false);   xhttp.send();   xmldoc=xhttp.responsexml; //fetch xml file contents    var nameel = xmldoc.documentelement.getelementsbytagname("name"); //get <name> tags in   (i=0; i<nameel.length; i++){     document.write("name" + + ": " + nameel[i].firstchild.nodevalue + "<br/>"); //write names   } }
