Thanks Xavier for the detailed explanation. I haven't tried your parser yet. I ended up writing my own XMLLayout that fixed the issues I listed.

Another issue I didin't show, for simplicity, is that LogMX doesn't understand XML entity for single quote (') - they are displayed as is in the viewer. <log4j:event logger="com.acme" timestamp="1559658306788" level="INFO" thread="[ACTIVE] ExecuteThread: '9' for queue: 'weblogic.kern...
