In processing XML similar to the fragment below, I have identified that within its <Set> element, five <Stamp> elements are of interest (because they all contain <Formats se-tenant="1">). Then that is your population to be grouped. how can I gather all of the <Value> elements from the subsequent <Stamp> elements of interest while ignoring: By grouping them, not by using axes. For the given XML fragment, I want to find these four <Value> elements and ignore the duplicated <Value> element: I hope the solution below helps. . . . . . . . . .
