Conditional loading of XML data set?

Question

Well, I've tried many different approaches to the following
seemingly simple issue. What I want to do is this:
dsParent = new Spry.Data.XMLDataSet("foo.xml","some/path");
dsChild = new
Spry.Data.XMLDataSet("{dsParent::@menu}","some/other/path"};
The trick, is that the @menu field is only defined for some
of the rows of the parent. I want to be able to filter this out as
follows:
<div spry:region="dsParent dsChild">
<div spry:repeat="dsParent">
<h3>{dsParent::@header}</h3>
<div spry:if="'{dsParentHead}'!=''">
<div spry:repeat="dsChild">
................ Stuff from dsChild ...................
</div>
</div>
</div>
Even better would be if the <div spry:repeat="dsChild">
just got repeated zero times so that there wasn't a need for a
conditional above it.
However, there doesn't seem to be any way to make this work.
When any rows with undefined @menu entries exist, my dynamic
regions never appear, and the mozilla javascript debugger shows
faults inside the loadURL code (presumably because the URL resolves
to an empty string). I tried to construct dsChild with a null
filename, then load the URL manually on events from the parent so
that I could only do so if the @menu was defined, but this scheme
doesn't seem to work (I believe that it is because there are no
events caused by dynamic region looping constructs, but I admit
that my understanding of what is happing in this code base is
sketchy at best).
IS there some way to do this? I really just want the dsChild
to produce a zero length table or otherwise get out of the way when
@menu is null..

Hi Noni,
Look at the OracleXMLSQL Utility (XSU). You can use it to do
your loading. Keep in mind though, that you will only be able
to
run the utility as a client side program (i.e. can use the java
api provided by the utility, or use it's command line front end).
