xpath in IE

[Tomas Olsson <tomas.olsson@soderhamn.mail.telia.com>]

Hi!
I wonder if its possible to load parts of a XML document in internet
explorer with xpath. Or do I have to load the whole document before I use
xpath.
If it isnt possible, how should I'll do if I only want to load parts of a
XML document?
A example is if I have a register and only wants the persons with the last
name Andersson.
