Two phase processing: Do not output empty tags from phase-1 XSLT 2.0 processing

Question

I have some complex XSLT 2.0 transformations. I\'m trying to find out if there is general purpose way to ensure that no empty tags are output. So... conceptually, a final st

Answer 1

This XSLT 2.0 transformation illustrates how multi-pass (in this case 2-pass) processing can be done:

when applied on this XML document:

  01
  02
  03
  04
  05
  06
  07
  08
  09
  10

It creates a result document in the first pass (which is captured in the $vPass1 variable), in which all elements with contents even integer are stripped off their content and are empty. Then, in the second pass, applied in a specific mode, all empty elements are removed.

The result of the transformation is:

   01
   03
   05
   07
   09

Do note the use of modes, and the special modes #all and #current.

Update: The OP now wants in a comment to delete "recursively" "all nodes that have no non-empty descendant".

This can be implemented simpler using no explicit recursion. Just change:
