SSAX-SXML Release 5.1
The SSAX parser and the SXML transformation tools and the examples are
now completely R5RS compatible. They should run on any R5RS-compatible
system. All low-level macros in the library proper and in the examples
are replaced with syntax-rules. In addition, the release contains
Scheme 48 packages and package declarations for the library and the
examples.

SXML version 3.0, SSAX release 4B
The current revision of the SXML specification is now 3.0. The
specification defines an S-expression-based data format for XML, and
for manipulation and querying of XML. The changes from the previous
revision, 2.5, are documented at the end of the specification.
The SSAX-SXML code, tests, documentation, and examples have been
updated to conform to SXML 3.0. The SSAX repository has been tagged
RELEASE-4B .

How SXML is used in industry and government
SXML is an S-expression-based data format for XML, and for manipulation and querying of XML. A paper and a complementary talk introduce SXML tools and describe the extensive practical experience of using SXML in real-life commercial and government projects.
The paper and the talk give motivation for and practical examples of S-expression-based implementations of W3C XML Recommendations, the embedding of XML data and XML query and manipulation tools into Scheme. A combination of W3C conformance with seamless integration into a programming language is a distinctive feature of our tools.
The paper and the talk are written in SXML itself, and are available from SSAX project's CVS repository. PDF files are available from:

Scheme48/SCSH, PLT Scheme 200 and vanilla R5RS ports
The SSAX parser and the SXML transformation tools have been generalized to vanilla R5RS Scheme and then specialized for Scheme48/SCSH and the upcoming PLT Scheme 200. The specialization relied on native module systems of Scheme48 and PLT Scheme (resp. functors and units).
This porting and specialization is the work of Michael Sperber. His message (as of Apr 18, 2002) on the SSAX-SXML mailing list gives more detail.

A _permissive_ HTML parser
SSAX is more than an XML parser -- it a library, which includes lexers
and parsers of various kinds. The library comes in handy to
permissively parse HTML documents or chunks that may contain
mismatched tags, unclosed tags, or other imperfections. The parser
still is able to deal with comments, parsed entities and many
different styles of HTML attributes. This is an example of using the
SSAX library for tasks other than XML parsing. See
SSAX/examples/README for more details.
