Does anyone know of any case-by-case comparison of jaxp to xalan?

Xalan implements TrAX, which is the JAXP API set for stylesheet transformation, so this isn't an either-or question;

I would side with Michaels opinion as well. Maybe your question requires some clarification.

Yes, both Xalan and Saxon have "Trax" Interfaces, Yes you can access both Saxon and Xalan API's independent of that Trax API. You have to understand that the Tranformer and Factories that you aquire from the JAXP/TRAX api are the implementions of those Factories/Transformers in Xalan or Saxon.

You could in such instances cast directly the Transformer or Factory to that implementation class to access any possible non-JAXP functionality. IMHO, They are not really mutually exclusive.

it's roughly equivalent to asking whether you should use SAX or Xerces.

Again, your not comparing "like with like" SAX is a generic parsing API that Xerces happens to support, there are other implementations of XML parsers which provide SAX API's (Crimson, Alfred, etc).

I believe Xalan still has some features which can't (yet?) be accessed through TrAX and require talking to Xalan directly. These may or may not be important to you for your application.

See my comment above concerning casting.
