EXSLT dynamic evaluate with Xalan

EXSLT dynamic evaluate with Xalan

Reply:     1     2     3     4     5     6     7  

I am trying to use the EXSLT dynamic function evaluate.  My stylesheet
contains:

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xalan="http://xml.apache.org/xalan"
xmlns:dyn="http://exslt.org/dynamic" extension-element-prefixes="dyn xalan">

I am not attempting to perform an xsl:import.

Later, in my transform, I call the evaluate function as shown:

  <xsl:variable name="datetest" select="dyn:evaluate($dataLink)"/>

I get the error:

file:///C:/trash/Howard%20Savin/EXSLT/publish.xsl; Line 56; Column 66; XSLT
Error (javax.xml.transform.TransformerException):
java.lang.NoSuchMethodException: For extension function, could not find
method
org.apache.xpath.axes.WalkingIteratorSorted.evaluate([ExpressionContext,] ).

Has anyone gotten this EXSLT function to work?

Thanks,
Howard
