This interface extends
org.xml.sax.ContentHandler and related interfaces
so that it can consume SAX events generated by a
org.xml.sax.SAXReader or
org.xml.sax.SAXFilter. Create a
transformerHandler by calling one of the
newTRansformerHandler( ) methods of a
SAXTransformerFactory.
Next, call the setResult( ) method to specify a
Result object that describes the result document
you'd like the transformation to produce. You may
also call gettransformer( ) to get the
TRansformer object associated with this
transformerHandler if you need to set output
properties or parameter values for the transformation.
Now, register the transformerHandler with the
SAXReader or SAXFilter object
by calling setContentHandler(
) , setDTDHandler(
), and setProperty( ).
`Then you use the property name
"http://www.xml.org/sax/properties/lexical-handler"
in the call to setProperties(
) to register the
TRansformerHandler as a
org.xml.sax.ext.LexicalHandler for the parser or
filter.
Finally, invoke one of the parse( ) methods on
your XMLReader or XMLFilter
object. This will cause the reader or filter to start parsing the
source document and translating it into method calls on the
transformerHandler. The
transformerHandler will transform those calls as
specified in the Templates or
Source object (if any) that was passed to the
original call to newtransformerHandler( ) and
generate a result document as directed by the
Result object that was passed to
setResult( ).
