XSieve: XSLT + Scheme
Oleg A. Paraschenko
I'm glad to announce XSieve, an XML transformation language based on
combination of XSLT and Scheme. XSieve make XSLT to be a general-purpose
language.
XSieve allows to switch between XSLT and Scheme modes. Data have two
alternative representations: as XML nodes and as Scheme values. Data is
automatically converted on demand. The Scheme representation is in fact
SXML format:
If you are intereste, read the full text of announcement, which is
biased towards the XML community:

Comments are welcome.

What advantages has it over SSAX-based transformation?

Python is executable pseudocode, Perl is executable line-noise.

XSieve=XSLT+Scheme in fact means XSieve=XSLT+SXML. SSAX-based
transformations are based on the SXML format, and therefore should be
fully compatible with XSieve. As result, SSAX-based transformations get
all XSLT features for free.

Aren't a SSAX (SXSLT) transformations a superset of what you can do
with XSLT? See:

Well, both XSLT and SXSLT are turing complete, so none of them is a
superset of the other. They mostly differ in the following areas:
* XSLT is a templating language, XSLTS is tree rewriting.
* XSLT has a big community and online resources.
* XSLT tools provide infrastructure: XInclude, XML catalogues, ready to
use stylesheets, etc.
The last two points show that XSLT is superiour to SXSLT.

That documents are not convincing. I prefer the following:
SXSLT: Manipulation Language for XML
http://okmij.org/ftp/papers/SXSLT.ps.gz
This document shows that SXSLT is superiour to XSLT.
Do you see the contradiction? XSieve solves it.

Well, I should have said "superior" or "more expressive".

This shows not that XSLT is superior to XSLT, but rather that the
community and resources available on XSLT is/are bigger. There is also
more Java than Scheme infrastructure available; does that mean that
the Java PL is superior to the Scheme PL?

There is no contradiction, it show just that many people/businesses
don't go after the best tools.

Always be wary of the Software Engineer who carries a screwdriver.
