I've got a hunch that what he really wanted to do was "pull" the
higher-level somethings rather than have them "pushed" at him, i.e. call a
function to get the next something rather than have the parser make a
callback, presumably because he needs to maintain some state and he'd like
to do it via flow-of-control rather than setting and testing state
variables.

If that's the case, he'd be better off building a wrapper that would feed
the input incrementally to expat and buffer up events, with the whole
thing driven by a "get next token" function that would return something
similar to a line of ESIS data.
