Access Child Node of a dataset

Question

I'm pointing to "root/data" in the XMLdataSet as var mdoReg
I'm using spry:region and spry:detailregion
Of course I can easily retrieve the node values of {name},
{usr}, {key} and so on.
-- but how do I access the children under <contacts>
and <links>
is there something like this {contacts/contact} that could
traverse in?
I have something like this for an XML structure;
<root>
<data>
<name>name</name>
<usr>usrname</usr>
<key>value</key>
<desc>description</desc>
<contacts>
<contact>contact-name</contact>
<contact>contact-name</contact>
<contact>contact-name</contact>
ect...
</contacts>
<links>
<link>link-value</link>
<link>link-value</link>
<link>link-value</link>
</links>
</data>
</root>
thanks

Hi Scott,
There is currently there is a limitation of Spry that doesn't
allow you do display nested data like this:
loop through /data
display 'name'
loop through contacts/contact for 'name'
display 'contact'
end loop
end loop
However, you can build a master-detail just like in the
products demo
You'll display the 'name', 'usrname', etc and when the user
click on one of the records you'll be able to display (in a
separate spry:region) the related links and contacts for that
'name'
In order to accomplish this you have to create those two
dataset to be dependent on the first one like this:
ds1 - selects "/root/data"
ds2 - selects "/root/data[name =
'{ds1::name}']/contacts/contact"
ds3 - same as 2
