Multiple xsl for a xml file

[Damiano Pezzotti <da...@libero.it>]

I want to associate dinamically an xsl stylesheet to an xml file.
In the Cocoon Documentation I found an example to do it.
I wrote this xml :

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

<xsp:processing-instruction name="xml-stylesheet">
  href="<xsp:expr>request.getQueryString()</xsp:expr>"
  type="text/xsl"
</xsp:processing-instruction>
<?cocoon-process type="xsp"?>
<?cocoon-process type="xslt"?>


<!DOCTYPE novel [
 <!ENTITY mdash "--">
 <!ENTITY ldquo "``">
 <!ENTITY rdquo "''">
 <!ENTITY lsquo "`">
 <!ENTITY rsquo "'">
 <!ENTITY hellip "...">
]>

<xsp:page 
  language="java" 
  xmlns:xsp="http://www.apache.org/1999/XSP/Core"
>

<novel>

 <front>
  <title>The Heart of Darkness</title>
  <author>Joseph Conrad</author>
......................................

In this mode I want to pass the xsl stylesheet as a parameter in the url.
But I have this exception

org.xml.sax.SAXParseException: The namespace prefix "xsp" was not declared.
