The main Xalan-Java 1 compatability package -- facilities for setting up and performing XSL transformations.

Use one of the {@link org.apache.xalan.xslt.XSLTProcessorFactory} static getProcessor methods to instantiate an {@link org.apache.xalan.xslt.XSLTProcessor}. The XSLTProcessor interface defines the XSLT processor API. You should never need to call the underlying implementation ({@link org.apache.xalan.xslt.XSLTEngineImpl}) directly.

Instantiate {@link org.apache.xalan.xslt.XSLTInputSource} objects for the XML input and the XSL stylesheet, and an {@link org.apache.xalan.xslt.XSLTResultTarget} object for the transformation output. You may construct these objects with a variety of containers/formats, including files or URLs, character streams,byte streams, SAX input streams or document handlers, and a DOM tree.

As a general rule, use the XSLTProcessor process method to perform a transformation, thereby filling the XSLTResultTarget object. For repeated transformations, to gather information from the stylesheet before you perform the transformation, or to set up the processor to function as a SAX document handler, use the XSLTProcessor processStylesheet method to compile the XSL stylesheet, which returns a {@link org.apache.xalan.xslt.StylesheetRoot} object with its own process method.
