Xalan: The org.apache.xalan.xsltc.trax.SmartTransformerFactoryImpl Class

Extends: javax.xml.transform.sax.SAXTransformerFactory

Members

Overview

This class is main implementation of transformer factory that uses an XSLTC transformer for the creation of Templates objects and uses the Xalan processor transformer factory for the creation of Transformer objects.

A Template is the runtime representation of processed transformation instructions.  While using Templates objects, you should ensure the Thread safety.

Method Overviews

This class is the concrete implementation of transformer factory. I have given examples of methods to create Templates object from an input source, how to create a transformer factory to perform the transformation.

Example of newTemplates(javax.xml.transform.Source):

This method is used to create a Templates object from a Source. Javax.xml.transform.Source is an interface so you have to provide a concrete implementation of Source interface. In my example I have used javax.xml.transform.stream.StreamSource.

            StreamSource source = new StreamSource(stylesheetURI);// stylesheetURI is the system URI for your xsl stylesheet.

            Templates templates = smartTransforer.newTemplates(source);

Example of newTransformer(javax.xml.transform.Source):

This method is used to parse a javax.xml.transform.Transformer Object. Using javax.xml.transform.Transformer object, you can do the actual transformation.         

 StreamSource source = new StreamSource(stylesheetURI);// stylesheetURI represents the stylesheet.

Transformer transformer = smartTransforer.newTransformer(source);

StreamSource sourceXML = new StreamSource(xmlURI);// xmlURI represents system URI of your input xml file.

 StreamResult result = new StreamResult(outURI);// outURI represents system URI of the output file.

If you want the result of your transformer to be shown in your command prompt, then you can use System.out  while creating Result.

StreamResult result = new StreamResult(System.out);

transformer.transform(sourceXML,result);

Example of newTransformer():

This method is used to create a Transformer object that copies the input document to the result. Uses the rg.apache.xalan.processor.TransformerFactory.

Transformer transformer = smartTransforer.newTransformer();
