I did not clearly expalain my problem.  My concern is when the
displaly disposes, the nsIDOMDocument loses the referrence. Looks like
nsiDOMdocument is tied to the display of mozilla instance..if I want
to do manipulation of the nsidomdocuement, i have to write logic in
either completed or changed event .   Now my problem has been
resolved. Thanks grant.
