Likewise, if "push" is a flow-control requirement such that the program stack is controlled by the data provider (the parser has the while loop), then SAX is "push". The "slurping" noise is caused by DOM's random access requirement. It has nothing to do with the flow-control aspect of the model.

Thus, it has a pull-interface (the program has the while loop) but only requires sequential-access. This works since a restricted version of DOM is being used. Best, Clark -- Clark C.
