[logback-user] Accessing an appender programatically not using a logger

Hi, I need to access an appender programatically. This appender is present in the configuration XML but the only way to access it seems to be through loggers that hold a reference to it. I would like to directly access it (for example by its name) without having to know which loggers it might be attached to. Is there a way to do this ? Gonçalo Luiz
