Does anyone know why the line(s) below would return 'null' or null?

xmlDoc.getElementsByTagName("description")[0].childNodes[0].nodeValue;

Thanks!

     var name =

     var coordinates =

     alert(coordinates);

     var content = '<table border="1" cellpadding="1" cellspacing="1">';
     content +=

     content +=

     content += '</table>';

     document.getElementById('content').innerHTML = content;

   }
