Subject RE: JSON transform - Analogous to XML/XSLT
Date Fri, 08 Apr 2011 14:22:21 GMT

Ummm, I guess I would consider Javascript as a means by which to do JSON transformations -
I could also use a myriad of languages & scripting to accomplish it as well.  But I would
not consider it intended to be XSLT in the analogy.  XSLT is explicitly designed (and frameworks
explicitly optimized) to transform XML.  I was looking for something that has been designed
(and implemented and optimized) for the purpose of transforming JSON.  If Javascript is the
best tool to transform JSON (at this time), then that's what I got.
