Re: X12 sees the writing on the wall.
Actually, the free SAX or DOM parsers, along with XSLT, could handle
Bosak's example quite readily - as XML supports Unicode in a first-class
manner.
It's kind of an unusual example, though, considering I would expect
most - if not all - element labels to be in Latin (you know: our
alphabet), with the data itself perhaps in pictograms depending on the
locale. Bosak's point was that semantics are the important issue, not
the file container or the parser. The same is true of EDI, and
understanding those semantics is what (I had thought) consumes most of
the time in implementing EDI.
But judging by some of the letters to this forum, getting the mechanics
of a particular translator to work may consume far more time than I had
ever imagined - tilting the argument even more in XML's favor. As
recently as 2000, I had guessed that maybe 5 or 10% of the effort in
implementing a transaction was consumed by the mechanics of mapping -
the rest going into analysis. If this figure was correct, then moving to
XML probably wouldn't be worth the effort, since it only optimizes the
syntax and mapping parts of the job. But if the mechanics of mapping
consume 50% or more of implementation time, the story changes. Remember
I'm the one who always stuck up for EDI - see my original article " Is
There Still Life Left in That Old EDI?," at the Novannet Resources page
at http://www.novannet.com/resources.html.
You know, I suppose I would rather learn a few things well - like Java,
Perl and XSD schemas - than to struggle with some of these expensive
proprietary EDI mapping systems with their onerous annual maintenance
fees, arcane GUI systems and obscure macro languages.

William:
I'l like to see one of your free parsers handle this XML:
