Adam Bosworth says:
"It is the thesis of this series of articles that [DOM/JDOM,
SAX/databinding, and XSLT] are only rarely suitable for either waypoint
[lossless transformation] or endpoint [lossy data extraction] processing.
As I wrote in the prior article, they place an intolerable burden on the
native processing of XML (coming up through the aegis of ECMAScript) and
XML Query (from the W3C), can vastly improve performance and productivity
for this sort of programming. "
native processing of XML"? I haven't heard of it, and Googleing didn't
turn up anything useful.
- Anyone want to speculate on why one might think that XQuery will be
vastly better than these other technologies for XML transformations, lossy
or otherwise? Technically, they are all more or less equivalent (assuming
one has an XPath library to find patterns in the XML). As far as
productivity is concerned, I would guess that it depends ... some people
are productive with procedural code and a generic Infoset-ish data model,
some are productive with building a customized object model from the XML
tokens and manipulating it, and some are comfortable with XSLT's
declarative template/transformation model. XQuery is one more approach
that some people are going to like (perhaps it will make XML streams look
like a good ol' database for SQL programmers), but I'm not aware of any
arguments that it will dramatically improve productivity or performance.
Thoughts, anyone? Or are we just being setup for a marketing pitch?
