I want use XRule calculator for calculate sum of CFLN and set into
Total tag. I want to know how can use XRule for calculate sum with
loop not direct address. does XRule have a function for check an xml
element has a specific child like Total and if it has then calculate
it.

Where can I found XRule function like iif,position or ...?

Best regards
