Regular Expressions in MOM 2005

I am writing a piece on rule tuning: disabling, performance thresholds, script parameters, etc. and wanted to do a piece on using regular expressions to filter events. This comes in really handy when you want to filter out unwanted events (I use it religiously in for ExBPA MP). I see John Hahn has a great start on this already with a nice piece on regular expressions. I will incorporate his reference into my piece and post later this week. In the meantime, you can see his tutorial here: http://msmvps.com/blogs/jfhann/archive/2005/08/15/62762.aspx
