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.
