Java in a Nutshell, 5th Edition

Name

XMLFormatter

Synopsis

This Formatter subclass converts a LogRecord to an XML-formatted string. The format( ) method returns a <record> element, which always contains <date>, <millis>, <sequence>, <level> and <message> tags, and may also contain <logger>, <class>, <method>, <thread>, <key>, <catalog>, <param>, and <exception> tags. See http://java.sun.com/dtd/logger.dtd for the DTD of the output document.

The getHead( ) and getTail( ) methods are overridden to return opening and closing <log> and </log> tags to surround all output <record> tags. Note however, that if an application terminates abnormally, the logging facility may be unable to terminate the log file with the closing <log> tag.
