Method Summary

TransformerHandler	getTransformerHandler(Source stylesheet) Same as getTransformerHandler(Source,XMLFilter), with filter set to null.
TransformerHandler	getTransformerHandler(Source stylesheet, XMLFilter filter) Return a TransformerHandler for a given stylesheet Source.
XSLTProcessor.TransformerHandlerAndValidity	getTransformerHandlerAndValidity(Source stylesheet) Same as getTransformerHandlerAndValidity(Source,XMLFilter), with filter set to null.
XSLTProcessor.TransformerHandlerAndValidity	getTransformerHandlerAndValidity(Source stylesheet, XMLFilter filter) Return a TransformerHandler and SourceValidity for a given stylesheet Source.
void	transform(Source source, Source stylesheet, Map params, Result result) Applies an XSLT stylesheet to an XML document.

Method Detail

getTransformerHandler

public TransformerHandler getTransformerHandler(Source stylesheet,
                                                XMLFilter filter)
                                         throws XSLTProcessorException

Return a TransformerHandler for a given stylesheet Source. This can be used in a pipeline to handle the transformation of a stream of SAX events. See TraxTransformer.setConsumer(org.apache.cocoon.xml.XMLConsumer) for an example of how to use this method.

The additional filter argument, if it's not null, is inserted in the chain SAX events as an XML filter during the parsing or the source document.

This method caches the Templates object with meta information (modification time and list of included stylesheets) and performs a reparsing only if this changes.

Parameters:

stylesheet - a Source value

filter - a XMLFilter value

Returns:

a TransformerHandler value

Throws:

XSLTProcessorException - if an error occurs

getTransformerHandlerAndValidity

public XSLTProcessor.TransformerHandlerAndValidity getTransformerHandlerAndValidity(Source stylesheet,
                                                                                    XMLFilter filter)
                                                                             throws XSLTProcessorException

Return a TransformerHandler and SourceValidity for a given stylesheet Source. This can be used in a pipeline to handle the transformation of a stream of SAX events. See TraxTransformer.setConsumer(org.apache.cocoon.xml.XMLConsumer) for an example of how to use this method.

The additional filter argument, if it's not null, is inserted in the chain SAX events as an XML filter during the parsing or the source document.

This method caches the Templates object with meta information (modification time and list of included stylesheets) and performs a reparsing only if this changes.

Parameters:

stylesheet - a Source value

filter - a XMLFilter value

Returns:

a TransformerHandlerAndValidity value

Throws:

XSLTProcessorException - if an error occurs

getTransformerHandler

public TransformerHandler getTransformerHandler(Source stylesheet)
                                         throws XSLTProcessorException

Same as getTransformerHandler(Source,XMLFilter), with filter set to null.

Parameters:

stylesheet - a Source value

Returns:

a TransformerHandler value

Throws:

XSLTProcessorException - if an error occurs

getTransformerHandlerAndValidity

public XSLTProcessor.TransformerHandlerAndValidity getTransformerHandlerAndValidity(Source stylesheet)
                                                                             throws XSLTProcessorException

Same as getTransformerHandlerAndValidity(Source,XMLFilter), with filter set to null.

Parameters:

stylesheet - a Source value

Returns:

a XSLTProcessor.TransformerHandlerAndValidity value

Throws:

XSLTProcessorException - if an error occurs

transform

public void transform(Source source,
                      Source stylesheet,
                      Map params,
                      Result result)
               throws XSLTProcessorException

Applies an XSLT stylesheet to an XML document. The source and stylesheet documents are specified as Source objects. The result of the transformation is placed in Result, which should be properly initialized before invoking this method. Any additional parameters passed in params will become arguments to the stylesheet.

Parameters:

source - a Source value

stylesheet - a Source value

params - a Map

result - a Result value

Throws:

XSLTProcessorException - if an error occurs
