There's no such thing as null values in XML. An empty element does not
have a null value. Rather it's value is the empty string. Perhaps you
could argue that an element that was simply not present had a null
value, but that's a stretch. A lot depends on exactly how your local
application defines the notion of "value" since it's not really
somethings that's in the core of XML, just something that gets layered
on afterwards.
