Handle multiple occurrences

Next is a difficult part of using DML: advanced processing of multiple occurrences. In a previous section of this guide you learned about cardinalities and you saw examples of ways to select occurrences of a specific node among all the existing occurrences.

In the following pages, you go one step further. The following questions are answered:

  • How do I map through a set of occurrences?
  • How do I generate as many occurrences as required by the output Business Document definition, or as many as do exist in the input?
  • How do I copy a complete tree of input nodes verbatim to the output?
