toString is not reliable to find out whether the document has been 
parsed as I think the result of toString depends on the 
implementation/parser used, it can return anything the parser 
implementor wants it to return.
Check
   System.out.println(document.getElementsByTagName("*"))
and I am sure it shows that there are elements in the document.
