  • SAX (Score:2)

    For what it's worth, it sounds like what you're doing is a job that SAX is perfect for - reading, transforming, writing. SAX cleanly gives you these layers in a well designed manner. Unfortunately the book you're learning from doesn't cover SAX very well, because it was started before the XML::SAX project was finalised, however there's another book published by New Riders called XML and Perl [amazon.co.uk] which is supposed to cover SAX better (I haven't received my copy yet).

    Not that you'd re-write all this now you have something that works, but this might be useful for future reference.
    • I'll give SAX a try. I have no problems with rewriting all my code, especially since I am trying to create an example for others to follow, not just a quick solution for a specific problem.

      Perl & XML has a chapter on SAX. I'll start there, and I have ordered the New Riders book. Let me know if you have more recommendations for good SAX tutorials or documentation! Otherwise I'll just start slogging through XML::SAX::Intro and friends.

      As I mentioned, I am particularly interested in exploiting the sy

      • Unfortunately in SAX readers and writers are distinct too, simply because the operations tend to be very different. So you would have to write separate modules that did both.

        However there's nothing stopping you unifying some of the code if it's relevant to do that. You could put functions that you would use for both reading and writing in a separate package.

        A good example to look at for readers is Pod::SAX. Also check out XML::Generator::DBI. As far as writers go, there's not much detail on them. I tend t
