How do i go about this?

public static void transverseDomTree(Node start){
          Node child;

get the text child node and call setNodeValue()

i think it should not be like this...
>>start.getNodeName().equals ("display-name"))
since what ever u traverse, the start will point to the argument what u have passed....

i think it should be like this...

if( child.getNodeName().equals ("display-name")) ){
       /* set the value of the child using the method u desginated, or directly to the field */

> if( child.getNodeName().equals ("display-name")) ){
