How so?  You can layer a next event style interface on top of expat by
maintaining a queue of events.  A request for the next event returns the
head of the queue; if the queue is empty, it fills the queue by reading
another chunk of input and passing it to XML_Parse() with event handlers
that append to the queue of events.
