please take look on my technical report - it is a bit old but
it gives an example of the same task done both with SAX
and pull parser:

SAX and XmlPull are both streaming XML parsing APIs
so efficiency wise from design point of view they are equivalent
in practice however it depends completely on API implementation
that you use (and for what kind of task implementation is coded for).

i would recommend to built sample/prototype application and try few
different APIs such as lower level (SAX, XmlPull), higher level (DOM,
JDOM) data binding (Castor, JAXME) and compare them to see
what is the most natural API and will be easier to maintain code
(smaller, easier to read, better reflect application design).

then and only then look on available API implementations and
chose the best that works for you (at least that is what should be
done if you have enough time to do right things  ..).

hope it helps,
