Does your list of items have a parent node? Odd if it doesn't.
I'm guessing it does so you can do something like this:
put 1 into tIndex
repeat for each line tNode in revXMLChildNames(treeID,"/items",cr,"item",true)
repeat for each line tChildNode in
revXMLChildNames(treeID,"/items/"&tNode,cr,,false)
put revXMLNodeContents(treeID,"/items/"&tNode&"/"&tChildNode)
into tData[tIndex][tChildNode]
end repeat
add 1 to tIndex
end repeat
