Correct, that's actually what I was refering too. The pull model is refered
to in memory parsing. The parser creates an in memory representation (data
structure) of the xml doc.
Now, what I would like to know is the difference between that and what Jeff
mentioned as a batch processing, which also creates an **in memory**
representation of the doc? DOM parsers are pull parsers.
When you guys say it loads directly, what do you mean. It doesn't use a
traversal to load into DOM.

Errr, no.
The pull model is that used by Microsoft .NET's XmlReader API[0] or
XPP[1]. In
the push model the API calls your methods as it sees parts of the XML
stream
while in the pull model you are in complete control of traversing the
XML
stream.
One way of looking at it is that in the pull model, the big while loop
that
iterates through all the nodes in document is hidden from you while in
pull
model you're the one that writes it.
