FourThought LLC (http://FourThought.com) announces the release of

                      4XSLT and 4XPath 0.8.1
                      A python implementation
                     of the W3C's XSLT language

4XSLT is an XML transformation processor based on the W3C's
for the XSLT transform language.  4XPath implements the W3C XPath
for indicating and selecting XML document components.


4XPath implements the full 4XPath recommendation except for the 'lang'
core function.

Currently, 4XSLT supports a sub-set of the XSLT recommendation including
the following:

Full expression support and attribute-value template expansion
xsl:include                     xsl:import
xsl:template                    xsl:apply-imports
xsl:apply-templates             xsl:copy
xsl:call-template               xsl:if
xsl:for-each                    xsl:choose
xsl:element                     xsl:when
xsl:attribute                   xsl:otherwise
xsl:text                        xsl:message
xsl:value-of                    xsl:variable
xsl:processing-instruction      xsl:param
xsl:comment                     xsl:with-param
xsl:strip-space                 xsl:key
xsl:preserve-space              xsl:copy-of
xsl:sort                        xsl:namespace-alias

and, of course, xsl:stylesheet, xsl:transform, literal elements and text

Using the xml output method, 4XSLT produces the result tree by throwing
events from the emerging SAX 2 standard to a handler, so it can be
modified to supply results to any SAX 2 consumer.  For the 'html' and
'text' output methods special SAX consumers produce HTML DOM nodes and
plain text respectively.


Changes in 0.8.1

 - 4XSLT implements xsl:xsl:sort and xsl:namespace-alias
 - 4XSLT now implements template priorities
 - 4XPath now has a clear DOM-query interface
 - many big-fixes and more extensive testing
