I have an XML unbounded element like this. 




Here, <Item> is an unbounded element. Input file can have 1 or more than 1 items. I have to sum up the quantity fields of all the items. I believe Identifier instance cannot be used since the element occurrence is undefined.

Is there a way to perform calculation on elements of unbounded element?
