[xslt] extension

[spinmar interfree it ()]

Hi all,

I have a stupid question but I can't understand how to use extensions.

I have noticed (with xsltproc --dumpextensions) that the function str:encode is included.

How can I use it in my c program? 

My xsl starts with:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; xmlns:str="http://exslt.org/strings"; extension-element-prefixes="str" version="1.0">


but the program givers me this error:

xmlXPathCompOpEval: function encode-uri not found
XPath error Unregistered function in str:encode-uri($str,true())


I suppose that I have to call some function in my main.

Can someone tell me how to use an extension function?

Thanks very much


--Marco
