What tool is useful for reading log4j log files? [closed]

Question

I'm looking for a text editor for reading log4j log files capable of auto-highlighting lines according to the threads that logged them. For example, all the lines which include [pool-1-thread-1] will be colored yellow and all the lines which include [pool-1-thread-2] will be colored green. This might be available as a more general feature of highlighting according to the contents of some regex match.

What tools support this feature?

If you know a way I'm not aware of to do it in EditPLus or UltraEdit -- even better.

EDIT: My files are plaintext (not XML), and I can't change that.

You can try OtrosLogViewer. It can highlight events based on String/regex or java code. Look at this screenshot:
