Geez, it would sure be nice to hear this discussion going on the TRaX design mailing list. The idea is to work towards a commonly understood XSLT API for java (and perhaps other languages). > That "future API" still lacks some features which are already > implemented in XT Why don't you suggest these features on the TRaX mailing list? On the other hand, TRaX is meant to be a normative API. There may still be reasons to go to a proprietary API. > .. but trax.Processor is not "extends org.xml.sax.Parser" ( that's > what XSLProcessorImpl is in XT ) The Processor produces stylesheets... and the TemplatesBuilder does extend ContentHandler. The Transformer extends XMLFilter, which is an XMLReader, which is the SAX2 replacement for org.xml.sax.Parser (you can still use an SAX1 parser with an adapter). > Current XT API allow me to knock Ux ( which is a container > for chained SAX1 components ) easily not changing a line of XT > code. TRaX does both push and pull chaining very well. > That's why to me there is simply no question what should > be used as embeddable engine - only XT, which already > has convenient and simple API (missing not only in current, > but even in the future versions of other engines). Maybe something to do with which you learned first? I never thought of XT's API as convenient or simple. -scott Paul Tchistopolskii <paul@xxxxxxx> To: xsl-list@xxxxxxxxxxxxxxxx Sent by: cc: (bcc: Scott Boag/CAM/Lotus) owner-xsl-list@mulber Subject: trax and sax.

I also hardly belive I'l ever use DOM ... ) Also: <quote> This object represents a Transformer, which is a SAX2 XMLFilter.

To me this all means that the API is a bit hypotetical ( and too complex for stupid human being ( me ) to understand and use ). > and (b) because as far as I > know TRAX is currently a paper specification with no implementations, so you > don't actually have the option of using it as an alternative to XT. At the moment each XSLT engine has it's own API for embedding. Current XT API allow me to knock Ux ( which is a container for chained SAX1 components ) easily not changing a line of XT code. I can do the same with other XSLT engines but it will be not that easy with their current APIs. For some reasons all the vendors of 'other' XSLT engines ( except XT ) announced that in the future they'll provide unified API for embedding their XSLT engines ( called TRAX ). That "future API" still lacks some features which are already implemented in XT ( providing me with tons of APIs which I don't need at all and don't understand if I need them in the future ). That's why to me there is simply no question what should be used as embeddable engine - only XT, which already has convenient and simple API (missing not only in current, but even in the future versions of other engines).
