gnu.xml.pipeline
Class XsltFilter

java.lang.Object
  extended bygnu.xml.pipeline.EventFilter
      extended bygnu.xml.pipeline.XsltFilter
All Implemented Interfaces:
ContentHandler, DeclHandler, DTDHandler, EventConsumer, LexicalHandler

public final class XsltFilter
extends EventFilter

Packages an XSLT transform as a pipeline component. Note that all DTD events (callbacks to DeclHandler and DTDHandler interfaces) are discarded, although XSLT transforms may be set up to use the LexicalHandler to write DTDs with only an external subset. Not every XSLT engine will necessarily be usable with this filter, but current versions of SAXON and Xalan should work well.

Constructor Detail

XsltFilter

public XsltFilter(String stylesheet,
                  EventConsumer next)
           throws SAXException,
                  IOException
Creates a filter that performs the specified transform. Uses the JAXP 1.1 interfaces to access the default XSLT engine configured for in the current execution context, and parses the stylesheet without custom EntityResolver or ErrorHandler support.

Parameters:
stylesheet - URI for the stylesheet specifying the XSLT transform
next - provides the ContentHandler and LexicalHandler to receive XSLT output.
Throws:
SAXException - if the stylesheet can't be parsed
IOException - if there are difficulties bootstrapping the XSLT engine, such as it not supporting SAX well enough to use this way.
