You can create Java classes with static methods to be called in your XSL 
stylesheet.

This works well with XT (see http://www.jclark.com/xml/xt.html).
This is a small exemple of use:

In Java:
-------
package com.edf.util;

public class C1 {
  public static String f1(String s) {
    return s;
  }
}

In XSL:
------
<xsl:stylesheet xmlns:xsl="http://www.w3.org/XSL/Transform/1.0";
   xmlns:ext="http://www.jclark.com/xt/java/com.edf.util.C1";
>
 ...
 <xsl:param:variable mame="var1">
 ...
 </xsl:param-variable>
 ...
 <xsl:if test="ext:f1(string($var1))=''">
 ...
 </xsl:if>
 ...
  
  
Best regards.
 
Didier.
