What are the > costs of picking the wrong API? Might it be because there is no official SAX spec? (is there?) Nor is there a conformance test suite (at least not one that I was able to find when I looked some months ago). I probably shouldn't really be replying here, as I'm _not_ an "experienced XML developer" - yet. Rather, I'm a newbie who's spent the last year learning as much as I can about all things XML, mainly through reading everything I can find (including this list) and experimenting with my own implementations of various W3C specs (in the language Xbase++ - so far I've implemented XML 1.0 (both a native verion and an interface to Expat), DOM Level 2, namespaces, DTD's/validation, XML Base, XPath, XML Schemas Part 2 ( Datatypes ), a fair whack of XSLT - since abandoned 'coz it was just too slow :-( , and am currently finishing off an implmentation of RelaxNG. In attempting to come to grips with RelaxNG, somebody on this list pointed me towards pytrex.py, which I stidied pretty closely - and in the process I also discovered how to do event-based processing (using Expat). Until then, I only had a theoretical notion of what it was about. I had heard and read quite a lot about SAX, of course, and tried several times to get into it, but without either a formal spec or a test suite, I just didn't feel very motivated towards learning or implementing it - particularly given that my DOM implementation seemed to work so well. Of course, I haven't yet had to work with multi-megabyte files or suchlike, so I haven't felt an urgent need for SAX. ( a lack of "labido" ?? ) I doubt there are many others as naive or as foolish as myself, but I do think the ready availability of a formal spec and/or a conformance test suite would serve to make SAX a _lot_ more approachable. (And now I just know that several people will jump forth to tell me that both of these things have existed since Moses was a boy, and that there are more horses arses in this world than there are horses! ;-) and of course - they're quite right! ) cheers, gary
