/**
* TransformDemo uses JAXP to acquire an XML Transformer. It uses the Transformer
* to transform an XML shopping cart into an HTML view of the shopping cart.
* The Transformer uses transform instructions in an XSLT (.xsl) file.
*
* The following JARs must be in your CLASSPATH:
* - jaxp.jar
* - xerces.jar (for SAX parser and DOM object implementations)
* - xalan.jar (for XSLT implementation)
*
* Download JAXP (which includes these JARs) here: http://java.sun.com/xml/
* Find additional Xerces and Xalan info here: http://xml.apache.org/
*
* Note: XSLT authoring/programming is beyond the scope of this tutorial.
* You"ll find good XSL info here: http://www.w3.org/Style/XSL/#learning
