This package implements SAX2-specific transformation APIs. It provides
classes which allow input from
events, and also classes that produce org.xml.sax.ContentHandler events. It
also provides methods to set the input source as an
XMLReader, or to use a
InputSource as the source. It also allows the
creation of a
XMLFilter, which enables
transformations to "pull" from other transformations, and lets the transformer

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
processingInstruction(String, String), with the

illustrates several transformations chained together. Each filter points to a
XMLReader, and the final transformation is
caused by invoking
parse(String) on the final
reader in the chain.
|TemplatesHandler||A SAX ContentHandler that may be used to process SAX parse events (parsing transformation instructions) into a Templates object.|
|TransformerHandler||A TransformerHandler listens for SAX ContentHandler parse events and transforms them to a Result.|
