Employment/Purpose

Transformer is used to translate a XML document to another with a XSTL template. 

 <?page contentType="text/html;charset=UTF-8"?>
 <x:transformer xsl="book.xsl" xmlns:x="xml">
     <book>
         <title>ZK - Ajax without the JavaScript Framework</title>
         <for-who>Web application designers and programmers who wish to implement
          rich Ajax web applications in the simplest way.</for-who>
         <author>Henri Chen and Robbie Cheng</author>
     </book>
 </x:transformer>

where transformer is a component of the XML component set, so we have to specify the namespace: xml. Otherwise, the native namespace is assumed, and the element is generated directly.

Then, let us assume the content of book.xsl is as follows. 

 <xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
     <xsl:template match="/">
         <html>
             <head>
                 <title>Book Info</title>
             </head>
             <body>
                 <h1>Book Info</h1>
                 <xsl:apply-templates select="book"/>
             </body>
         </html>
     </xsl:template>
     <xsl:template match="book">
         <dl>
             <dt>Title:</dt>
             <dd><xsl:value-of select="title"/></dd>
             <dt>Who is this book for:</dt>
             <dd><xsl:value-of select="for-who"/></dd>
             <dt>Authors</dt>
             <dd><xsl:value-of select="author"/></dd>
         </dl>
     </xsl:template>
 </xsl:stylesheet>

Then, the generated XML output will be XHTML as follows. 

<html>
	<head>
		<META http-equiv="Content-Type" content="text/html; charset=UTF-8">
			<title>Book Info</title>
	</head>
	<body>
		<h1>Book Info</h1>
		<dl>
			<dt>Title:</dt>
			<dd> ZK - Ajax without the JavaScript Framework</dd>
			<dt>Who is this book for:</dt>
			<dd>Web application designers and programmers who wish to implement
				rich Ajax web applications in the simplest way.</dd>
			<dt>Authors</dt>
			<dd> Henri Chen and Robbie Cheng</dd>
		</dl>
	</body>
</html>
