The problem is that you call initStandardObjects twice and connect
those scopes. initStandardObjects adds all the standard constructors,
etc., to the scope, so your scope chain has *two* copies of these
standard objects, including the "XML" constructor. Try removing the
second initStandardObjects and just create a plain JavaScript object
by calling cx.newObject instead.
