XOM API for Processing XML with Java

[Elliotte Rusty Harold <elharo AT ibiblio.org>]

It's not quite that simple. There's a significant cost in API complexity
(especially since you have methods that don't work unless you know the
magic incantation) and even if you don't ask for it, there's still an extra
reference per object being stored.
