XSLTransformer.java - XML Transformer

<< XSL (Extensible Stylesheet Language)

<< JDK (Java Development Kit) Tutorials

This section provides a tutorial example on how to write an XML transformer program, XSLTransformer.java, using XSL (Extensible Stylesheet Language).

Here is my first XML transformation program using XSL (Extensible Stylesheet Language): XSLTransformer.java:

/**

import java.io.*;
import javax.xml.transform.*;
import javax.xml.transform.stream.*;
class XSLTransformer {
   public static void main(String[] args) {
      try {
      	 File sf = new File(args[0]); // source file
      	 File rf = new File(args[1]); // result file
      	 File tf = new File(args[2]); // template file
         TransformerFactory f = TransformerFactory.newInstance();
         Transformer t = f.newTransformer(new StreamSource(tf));
         Source s = new StreamSource(sf);
         Result r = new StreamResult(rf);
         t.transform(s,r);
      } catch (TransformerConfigurationException e) {
         System.out.println(e.toString()); 	
      } catch (TransformerException e) {
         System.out.println(e.toString());
      }
   }
}

Let's try this program with my hello.xml as the source file:

<?xml version="1.0"?>
<p>Hello world!</p>

and my hello.xsl as the template file that contains the transformation style rules:

<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:template match="p">Hello world.! - From hello.xsl.</xsl:template>
</xsl:stylesheet>

Run "java XSLTransformer hello.xml hello.out hello.xsl", I got in hello.out:

<?xml version="1.0" encoding="UTF-8"?>
Hello world! - From hello.xsl.

The result shows that my XML file has been transformed correctly.
