[xslt] Problems using functions with xsl

["Pedro Rocha" <pedro_jrocha hotmail com>]

Hi,

I'm having problems using the extention functions with xsl.

I've got the following error messages:

xmlXPathCompOpEval: function testparam not found
XPath error : Unregistered function
xmlXPathCompiledEval: evaluation failed
runtime error: file file:///c%3A/temp/xml/prueba.xsl line 234 element 
value-of
xsltValueOf: text copy failed

This is the xsl file:
------------------------------------------------------------------------------------------------------------------
<?xml version='1.0'?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
               xmlns:func="http://exslt.org/functions";
               extension-element-prefixes="func"
               version="1.0">

   <func:function name="func:testparam">
       <xsl:param name="foo" select="'Test'"/>
       <xsl:param name="bar" select="concat($foo, ' succeeded')"/>
       <func:result select="$bar"/>
   </func:function>

   <xsl:template match="/">
       <xsl:value-of select="func:testparam()" />
   </xsl:template>
</xsl:stylesheet>
------------------------------------------------------------------------------------------------------------------

I had a similar problem when I was trying to use the exslt str functions... 
it was because i didn't call the function exsltRegisterAll();

Any clue?

Thanks,

Pedro
