RE: [xsl] function-available() problem while using Saxon

["Michael Kay" <mike@xxxxxxxxxxxx>]

Curious.

Stylesheet:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";  
version="2.0">
<xsl:template match="/">     
      <ans><xsl:value-of select="function-available('saxon:evaluate-node')" 
                    xmlns:saxon="http://saxon.sf.net/"/></ans>
</xsl:template>
</xsl:stylesheet>

Command:

java -jar c:\saxon-build\saxon8.3\saxon-b\saxon8.jar -t test.xsl test.xsl

Result:

Saxon 8.3 from Saxonica
Java version 1.5.0
Stylesheet compilation time: 641 milliseconds
Processing file:/c:/temp/test.xsl
Building tree for file:/c:/temp/test.xsl using class
net.sf.saxon.tinytree.TinyBuilder
Tree built in 0 milliseconds
Tree size: 9 nodes, 21 characters, 3 attributes
<?xml version="1.0" encoding="UTF-8"?><ans>true</ans>
Execution time: 70 milliseconds

A possible explanation is that you are running with extension functions
disabled: how is Saxon being invoked? Another possibility is that you aren't
actually running Saxon at all - add a call on system-property('xsl:vendor')
to the stylesheet to check.
