An optimization fort XSLT is the use of
translets
. The
translet
framework reads a stylesheet
and generates a
Translet
class, which is a compiled Java program that transforms XML ac-
cording to that particular stylesheet. This eliminates the overhead of reading the stylesheet
each time a document is translated. Translets have been incorporated under the name XSLTC
into the
Apache XML Xerces-Java project
.
Parsing XML with SAX
Problem
You want to make one quick pass over an XML file, extracting certain tags or other informa-
tion as you go.
Solution
Simply use SAX to create a document handler and pass it to the SAX parser.
Discussion
The XML
DocumentHandler
interface specifies a number of “callbacks” that your code must
provide. In one sense, this is similar to the
Listener
interfaces in AWT and Swing, as
