XSL Transformations (SAP Library

XSL Transformations

Use

You can use the XSL Transformation part of JAXP to transform source documents into result documents, by applying a stylesheet or just converting from one type of source (for example DOM) to a different kind of result (for example SAX). The source and result will represent one and the same document. You can also indent the source document to set a transformer using:

transformer.setOutputProperty(OutputKeys.INDENT, "yes");

transformer.transform(new StreamSoruce("original"), new StreamResult("indented");

Features

The classes related to the XSL Transformations are:

· Source Types

¡ javax.xml.transform.Source

¡ javax.xml.transform.stream.StreamSource

¡ javax.xml.transform.dom.DOMSource

¡ javax.xml.transform.sax.SAXSource

· Result Types

¡ javax.xml.transform.Result

¡ javax.xml.transform.StreamResult

¡ javax.xml.transform.DOMResult

¡ javax.xml.transform.SAXResult

Example

public class JAXPXSLTExample {

public static void main(String args[]) {

//get a new TransformerFactory from the underlying

//implementation

TransformerFactory factory = TransformerFactory.newInstance();

Transformer transformer = null;

Templates template = null;

StreamSource xmlSource = null;

StreamSource xslSource = null;

StreamResult result = null;

try {

// a new StreamSource from a file name

xmlSource = new StreamSource("data/cars.xml");

xslSource = new StreamSource("data/cars1.xsl");

// a new StreamResult to a file name (it is automatically

//closed on exit)

result = new StreamResult("data/cars1.html");

// get a new Templates object for this stylesheet

template = factory.newTemplates(xslSource);

// get a new Transformer from the Templates

transformer = template.newTransformer();

// perform the transformation

transformer.transform(xmlSource, result);

// it is not needed to close the Stream result since it is

//output to a file name

}
