13 Aug. 2006 FXSL for XSLT 2.0 (version 2)

================================

Much work has been done in this release.

The main new results:

  • Almost all standard XPath 2.0 functions (F & O) have now higher-order FXSL wrappers that makes possible to use them as higher order functions and to create partial applications from them.

  • Some standard XSLT 2.0 functions and instructions have now higher-order FXSL wrappers that makes possible to use them as higher order functions and to create partial applications from them.

  • All standard XPath 2.0 operators (F & O) have now higher-order FXSL wrappers that makes possible to use them as higher order functions and to create partial applications from them.

  • All standard XPath 2.0 constructors have now higher-order FXSL wrappers that makes possible to use them as higher order functions and to create partial applications from them.

  • Currying and partial application uses dynamic type detection of the arguments of the function. On the final evaluation of the function when all arguments have been specified the typed values of the arguments are reconstructed using the recorded type information.

This is a maintenance release. One major bug has been systematically fixed within all stylesheet modules.

This affects the way in which template references should be declared.

Any template, a reference node to which will be passed as a parameter to an FXSL xsl:function or xsl:template, now must have the

  mode="f:FXSL"

attribute, where the prefix "f" is associated to the FXSL namespace-uri:

  xmlns:f="http://fxsl.sf.net/"

Example:

<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:foldl-func="foldl-func"
xmlns:f="http://fxsl.sf.net/"
exclude-result-prefixes="f foldl-func"
>

   <xsl:import href="func-foldl.xsl"/>

   <!-- This transformation must be applied to:
        numList.xml 
     -->
   <foldl-func:foldl-func/>
   <xsl:variable name="vFoldlFun" select="document('')/*/foldl-func:*[1]"/>
    <xsl:output  encoding="UTF-8" omit-xml-declaration="yes"/>

    <xsl:template match="/">
      <xsl:value-of select="f:foldl($vFoldlFun, 1, 1 to 10 )"/>
    </xsl:template>
    
    <xsl:template match="*[namespace-uri() = 'foldl-func']"
     mode="f:FXSL">
         <xsl:param name="arg1" select="0"/>
         <xsl:param name="arg2" select="0"/>
         
         <xsl:value-of select="$arg1 * $arg2"/>
    </xsl:template>

</xsl:stylesheet>

Using unique mode is necessary to ensure that no other template will be selected for processing (note that the FXSL stylesheet modules are imported into unknown user's code).

Cheers,

Dimitre Novatchev.
