Here is an example from the tests in log4j:
http://svn.apache.org/viewvc/logging/log4j/companions/receivers/trunk/src/test/resources/org/apache/log4j/rewrite/property.xml?view=markup&pathrev=564831
<appender name="F1" class="org.apache.log4j.FileAppender">
<param name="file" value="temp"/>
<param name="append" value="false"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%p %c - p1:%X{p1} p2:%X{p2}
%m%n"/>
</layout>
</appender>
<appender name="A1" class="org.apache.log4j.rewrite.RewriteAppender">
<appender-ref ref="F1"/>
<rewritePolicy
class="org.apache.log4j.rewrite.PropertyRewritePolicy">
<param name="properties" value="p1=Hello,p2=World,x1=3.1415"/>
</rewritePolicy>
</appender>
<root>
<level value ="debug" />
