This seems to go totally against what most people are trying to do. If
you call getChild, you really want to know if the child was there or not. 
Having a default value returned doesn't seem too useful for anyone...
correct me if I'm wrong on that :-)

For something simple like Properties, it makes sense. For a child
element, you could be talking about a whole structure ( the "body" 
child of an "html" Element, for example). 

Did this ever get resolved? What is the current standing of returning
null vs. throwing NoSuchElementException from getChild? I got the
feeling last week that we have not reached any consensus on this...

I'm still for a null return value.
