Single data set, loaded once, with multiple xpath paths?

Question

All,
Is it possible to load xml via a URL one time on a page
request and then
create mutliple datasets from that single call using
different xpath
expressions? sort of like doing a mega query then creating
subsets of that
query?
something like:
<root>
<process type="1" blah="blah"/>
<process type="1" blah="blah2"/>
<process type="2" blah="blah3"/>
</root>
ds1 = new XMLDataSet(blah.cfm,"/root/process[@type=1]";
ds2 = new XMLDataSet(blah.cfm,"/root/process[@type=2]";
what i really need to do is make that cfm call one time per
load.
thanks for any help.

Surely. Sorry for not being more specific earlier.
I'm currently using the tab widget. there are about 5 tabs
total. each of
those tabs represents a list of process in a given "status",
like "running",
"pending", etc. Currently, the way I create this is to run a
big old query
that gets ALL processes, and then I loop over that query,
grouping on the
Process Status, and create a tab for each status. I'm not
using any
spry:repeat regions or anything like that currently. In fact,
the only spry
i'm using at all is for the tab widget. the query is just a
query that runs
when the page loads. it's not doing any spry data loading
with XMLDataSet or
anything.
However, I'd like to convert this process to using the
XMLDataSet so that I
can use the spry repeat regions. What I'd like, then, is to
pass a cfm page
as the XML param. this would return the same query i'm
running now, except
in xml format. I'd also like to pass the loadInterval param
so that I can
avail myself of the automatic data refreshing so that all of
the tabs will
have their content updated at the specified interval, as
opposed to doing it
with a page refresh which is how I do it now (which is just a
brute force
way of rerunning the query and recreating all html).
so in the end what i end up with is 5 tabs, each representing
a status,
whose data comes from the same xml but whose tab content is a
subset of that
xml. the loadinterval then ensures that all tabs are updated
at the
appropriate frequency.
how's that? clearer?
thanks again!
