Hi, I am trying to use a saxon extention function, but I keep getting
XPathProcessorException Extension function unknown (I have tried saxon:parse,
saxon:evaluate ++). I know that the saxon*.jar file which contains the class
"net.sf.saxon.functions.Parse" is in the class path. Can anyone please
help me? This is my xsl file: <?xml version="1.0"
encoding="ISO-8859-1"?> <xsl:stylesheet
version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/"> <xsl:variable
name="xmlContent" select="saxon:evaluate(something)"
xmlns:saxon="http://saxon.sf.net/"/>
</xsl:template> </xsl:stylesheet> This is the exception:
Caused by: org.apache.xpath.XPathProcessorException: Extension function
http://saxon.sf.net/ : evaluate is unknown at
org.apache.xalan.extensions.ExtensionsTable.extFunction(ExtensionsTable.java:241) at

The stack trace shows that you are not running Saxon at all, you are running Xalan.
It seems you are using the JAXP XPath interface. Make sure you load the Saxon version of
the XPath factory, class name net.sf.saxon.xpath.XPathFactoryImpl. The safest way of
achieving this is to instantiate it directly, rather than relying on the JAXP classpath
search. Another way is to set the system property javax.xml.xpath.XPathFactory.
