Field Summary

static String	DEFAULT_FACTORY The default factory identifier.
static String	ROLE The role implemented by an XSLTProcessor.

Method Summary

TransformerHandler	getTransformerHandler(Source stylesheet) Same as getTransformerHandler(Source,XMLFilter), with filter set to null and factory set to null.
TransformerHandler	getTransformerHandler(Source stylesheet, XMLFilter filter) Return a TransformerHandler for a given stylesheet Source.
void	setSourceResolver(SourceResolver resolver) Deprecated. The processor can now simply lookup the source resolver.
void	setTransformerFactory(String classname) Set the TransformerFactory for this instance.
void	transform(Source source, Source stylesheet, Parameters params, Result result) Applies an XSLT stylesheet to an XML document.

Field Detail

ROLE

static final String ROLE

Method Detail

setSourceResolver

void setSourceResolver(SourceResolver resolver)

Deprecated. The processor can now simply lookup the source resolver.

Set the SourceResolver for this instance. The resolver is invoked to return a Source object, given an HREF.

Parameters:

resolver - a SourceResolver value

setTransformerFactory

void setTransformerFactory(String classname)

Set the TransformerFactory for this instance. The factory is invoked to return a TransformerHandler to perform the transformation.

Parameters:

classname - the name of the class implementing TransformerFactory value. If an error is found or the indicated class doesn't implement the required interface the original factory of the component is maintained.

getTransformerHandler

TransformerHandler getTransformerHandler(Source stylesheet,
                                         XMLFilter filter)
                                         throws ProcessingException

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 Source object and performs a reparsing only if this changes.

Parameters:

stylesheet - a Source value

filter - a XMLFilter value

Returns:

a TransformerHandler value

Throws:

ProcessingException - if an error occurs

getTransformerHandler

TransformerHandler getTransformerHandler(Source stylesheet)
                                         throws ProcessingException

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

Parameters:

stylesheet - a Source value

Returns:

a TransformerHandler value

Throws:

ProcessingException - if an error occurs

See Also:

TraxTransformer.setConsumer(org.apache.cocoon.xml.XMLConsumer)

transform

void transform(Source source,
               Source stylesheet,
               Parameters params,
               Result result)
               throws ProcessingException

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 Parameters value

result - a Result value

Throws:

ProcessingException - if an error occurs
