Choose one of the following transforms to implement an arithmetic operation to set the value of an output element:
Use the fn:sum transform to calculate the sum of the values of
multiple input elements.
For more information, see fn:sum.
Use the Custom XPath transform to implement any of the following
arithmetic operations: addition (+), subtraction (-), multiplication (*), division (div),
or any combination of these operations.
Note: You can only use as arguments of an arithmetic operation non-repeating simple type input elements.
