I believe that it isn't so much of a way of parsing, as a way of
communicating between the parser and the application using the data
from the XML file.


In the "pull" case, the parser reads up all of the data from the XML
file and saves it. The application then asks for particular data as
it needs it.


In the "push" case, the parser reads the XML file and passes data to
the application as it is parsed. It is then up to the application to
save the data that it needs as the file is being read in.


This is not the same kind of question as bottom-up v.s. top-down
parsing, but how you view the communication between the parser and the
application.
