To be able to look up nodes via xpath expressions you need a dom tree to
navigate to match the pattern from the expression. These patterns can
become arbitrarily complex and they typically involve nodes far appart
in the document (or even across multiple documents !), so matching with
a stream-based protocol would be very hard (you would have to reread the
stream over and over again).
