I don't think it was a fair answer. Both tokenizing and tree processing have
their pros and cons. Advantages of SAX are:

The question was not about general events vs trees, but specifically, what's the most effective approach for feeding an xslt processor - emitting SAX events or building DOM object. Correct me if I'm wrong.

Disadvantages of SAX are:

  * Easily forgets previous elements it worked on
  * Not easy to re-order elements
  * Cannot validate an XML document
  * Canot easily verify ID-REF links

I'd like to discuss it, but it seems to be sort of offtopic here.

In fact, SAX-like processors are used to produce DOM-like processors.

That's why I have recommended SAX as input for xslt. If almost every xslt processor always builds internal tree from its input, I don't see any advantage of building possible huge DOM object just to move data.
