Hi Heiko,

original email address]

No, that isn't the problem: exsl:object-type() and exsl:node-set()
work fine from Apache, so I assume it must be finding the libraries. And 
Apache accepts:
xmlns:exsl="http://exslt.org/common";
without complaining at all; it only complains about:
xmlns:func="http://exslt.org/functions";

The sequence of error messages I get in the Apache error log is:

Failed to register module data: http://exslt.org/functions
xmlXPathCompOpEval: function testfunc not found
Error xpath.c:9306: Unregistered function

My libexslt is version 0.7.4; 

/usr/include/libexslt/exslt.h includes the line:
  
#define EXSLT_FUNCTIONS_NAMESPACE ((const xmlChar *) 
"http://exslt.org/functions";)

I've appended the test file I'm using below (when run from the command 
line this generates:

Input type was: RTF;
changed to: node-set;
passed through func: node-set

I asumme it's me doing something silly; but just to reassure me, are
other people out there using libexslt/XML::LibXSLT/Apache?

Thanks
Graham
