Subject ExpressionFilter parse error with "&&"
Date Fri, 26 Nov 2010 19:04:11 GMT
I am using ExpressionFilter to filter out an ERROR event with the text "test123".  However,
I'm getting a XML SAXParseException:
The entity name must immediately follow the '&' in the entity reference.

      <filter class="org.apache.log4j.filter.ExpressionFilter">
        <param name="Expression" value="LEVEL >= WARN && MSG ~= test123"/>
        <param name="AcceptOnMatch" value="false"/>
      </filter>

This works if I only have <param name="Expression" value="MSG ~= test123"/> but not
when I add the LEVEL condition.


I have in my classpath:
apache-log4j-extras-1.1.jar, log4j-1.2.16.jar, jakarta-oro-2.0.8.jar

What's wrong?
