check the <cms:query> tag. I didn't tried it but it could work:

Good luck,

Yes, it was actually the first thing I tried - but I think I was up
too late when I tried it the first time because I had a typo in the
EL where I was trying to get the data out of the query results! :)
(friends don't let friends code drowsy)
Here's what I am using now that works just fine:
-----
<cms:query var="businesses" nodeType="business" repository="data"
query="${businessDirQuery}" />
<c:if test='${empty businesses }' >
<h2>No business found for this category / region</h2>
</c:if>
<c:forEach var="businessNode" items="${businesses}">
<cms:setNode var="business" contentNode="${businessNode}" />
<jsp:directive.include file="../data-decorators/business-
directory-entry.jspf"/>
</c:forEach>
------
I'm using the jsp:directive.include to let me split off the part that
does the decoration of the data nodes in a similar way to how
paragraph templates work. The setNode is invaluable because it
exposes a map of all the attributes.
The only strange thing I noticed was that my field "phoneNumber" was
giving me a number format exception when it was being rendered -
which is strange since it is stored as a string! The easy workaround
is to just use <c:out value="${phoneNumber} " /> (with the extra
space after the phone number variable to force it to concatenate the
phone number with a blank space and therefore treat it as a String...)
In any case - the easiest way to get data out of the data module
seems to be:
1. Use the cms:query
2. Use the cms:setNode to expose the data's properties in a map
and in my case, splitting out the "template" that renders those
things into a separate file.
