Retrieving all DOM descendants
First observation of the day: IE 5 for Windows doesn’t understand
element.getElementsByTagName('*') to retrieve all descendants of an element in the DOM.
element.all has the desired effect for that browser. So to retrieve all descendants in a way that will work on standards compliant browsers plus IE 5, the following seems to be the best bet:
var elements = element.all ? element.all : element.getElementsByTagName('*');
