Method Detail

pipeDocument

public void pipeDocument(XSLProcessorContext context,
                         ElemExtensionCall elem)
                  throws TransformerException,
                         TransformerConfigurationException,
                         SAXException,
                         java.io.IOException,
                         java.io.FileNotFoundException

Extension element for piping an XML document through a series of 1 or more transformations.

Common usage pattern: A stylesheet transforms a listing of documents to be
 transformed into a TOC. For each document in the listing calls the pipeDocument
 extension element to pipe that document through a series of 1 or more stylesheets 
 to the desired output document.
 
 Syntax:
 <xsl:stylesheet version="1.0"
                xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:pipe="http://xml.apache.org/xalan/PipeDocument"
                extension-element-prefixes="pipe">
 ...
 <pipe:pipeDocument   source="source.xml" target="target.xml">
   <stylesheet href="ss1.xsl">
     <param name="param1" value="value1"/>
   </stylesheet>
   <stylesheet href="ss2.xsl">
     <param name="param1" value="value1"/>
     <param name="param2" value="value2"/>
   </stylesheet>
   <stylesheet href="ss1.xsl"/>     
 </pipe:pipeDocument>
 
 Notes:

• The base URI for the source attribute is the XML "listing" document.
• The target attribute is taken as is (base is the current user directory).
• The stylsheet containg the extension element is the base URI for the stylesheet hrefs.

usePipe

public void usePipe(java.util.Vector vTHandler,
                    java.lang.String source,
                    java.lang.String target)

                    SAXNotRecognizedException

Uses a Vector of TransformerHandlers to pipe XML input document through a series of 1 or more transformations. Called by pipeDocument(org.apache.xalan.extensions.XSLProcessorContext, org.apache.xalan.templates.ElemExtensionCall) and #main.

Parameters:

vTHandler - Vector of Transformation Handlers (1 per stylesheet).

source - absolute URI to XML input

target - absolute path to transformation output.
