Hi, i'm working with some xml that gives format to a PDF.

im using a currency format="{0:n2}" and it also works with format="{o:c}" but i want to desapear the info when theres 0 values so people dont get confused if they see info that is not necessary to be seen (like 0% discount and its result form the subtotal)... is there a way i can hide or validate null so it brings no info?
