I really liked the way Wendell Piez put it a while ago on this list:

  XSLT, especially XSLT 1.0, is at its best when the incoming data
  is well designed. When it isn't, one has to call on more advanced
  techniques such as processing text nodes explicitly. Of course,
  XSLT also exerts a gravitational pull on XML semantics, such that
  well-designed XML comes to be the XML that XSLT can handle without
  fuss. -- Wendell Piez, 30.09.2008, XSL-List

I can hardly argue with that :-> except that David's case is one we can probably trust not to fall into the category of "redesign your XML and your XSLT will simplify". Depending on the application and the constraints on the source data, some XSLT is going to be computationally intensive no matter what you do. David's 11 predicates might have been 23 predicates if his XML were not so well designed.


Cheers,
Wendell
