How can I use XSLT 2.0 and XSLT 3.0 in Java?

Question

I am able to use XSLT 1.0 in Java as shown in the folllowing example :-

copy.xml

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="identityxfm.xsl"?>
<catalog>

copy.xsl

<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
      xmlns:xsl="http://www.w3.org/1999/XSL/Transform" >

  <xsl:template match="/ | @* | node()">
    <xsl:copy>
      <xsl:apply-templates select="@* | node()"/>
    </xsl:copy>
  </xsl:template>

</xsl:stylesheet>

Copy.java

package com.data.transform;

import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.stream.StreamResult;
import javax.xml.transform.stream.StreamSource;

public class Copy {

    public static void main(String args[]) throws Exception {
        StreamSource source = new StreamSource("copy.xml");
        StreamSource stylesource = new StreamSource("copy.xsl");

        TransformerFactory factory = TransformerFactory.newInstance();
        Transformer transformer = factory.newTransformer(stylesource);

        StreamResult result = new StreamResult(System.out);
        transformer.transform(source, result);
      }
}

Output

<?xml version="1.0" encoding="UTF-8"?><?xml-stylesheet type="text/xsl" href="identityxfm.xsl"?><catalog>
    <book id="bk101">

But, now I want to use few things that are included in XSLT 2.0 and XSLT 3.0 (like xsl:analyze-string, xsl:try etc.) in Java. How can I do that ?

Answer 1

Get Saxon 9 HE from Maven or Sourceforge and put it on the classpath, then you have XSLT 2.0 support with Saxon 9.x before 9.8 or XSLT 3.0 support (except streaming, higher order functions, xsl:evaluate, schema-awareness, backwards compatibility) with 9.8. For full XSLT 3.0 support you need to download Saxon 9 PE or EE from Saxonica and put it together with a license you buy or a trial licence you request on the classpath.
