Package javax.xml.transform.sax
The SAXSource class allows the
setting of an XMLReader to be used for pulling
parse events, and an InputSource that may be used to
specify the SAX source.
The SAXResult class allows the
setting of a ContentHandler to be the receiver of
SAX2 events from the transformation.
The SAXTransformerFactory extends
TransformerFactory to provide factory
methods for creating TemplatesHandler,
TransformerHandler, and
XMLReader instances.
To obtain a SAXTransformerFactory,
the caller must cast the TransformerFactory
instance returned from
TransformerFactory.newInstance().
The TransformerHandler interface
allows a transformation to be created from SAX2 parse events, which is a "push"
model rather than the "pull" model that normally occurs for a transformation.
Normal parse events are received through the
ContentHandler interface, lexical events such as
startCDATA and endCDATA are received through the
LexicalHandler interface, and events that signal
the start or end of disabling output escaping are received via
ContentHandler.processingInstruction(java.lang.String, java.lang.String), with the
target parameter being
Result.PI_DISABLE_OUTPUT_ESCAPING and
Result.PI_ENABLE_OUTPUT_ESCAPING. If
parameters, output properties, or other features need to be set on the
Transformer handler, a Transformer reference
will need to be obtained from
TransformerHandler.getTransformer(), and
the methods invoked from that reference.
The TemplatesHandler interface
allows the creation of Templates objects
from SAX2 parse events. Once the ContentHandler
events are complete, the Templates object may be obtained from
TemplatesHandler.getTemplates(). Note that
TemplatesHandler.setSystemId(java.lang.String) should
normally be called in order to establish a base system ID from which relative
URLs may be resolved.
The SAXTransformerFactory.newXMLFilter(javax.xml.transform.Source)
method allows the creation of a XMLFilter, which
encapsulates the SAX2 notion of a "pull" transformation. The resulting
XMLFilters can be chained together so that a series of transformations
can happen with one's output becoming another's input.
