Log parser Powershell Excluding content.

Hi,

I have been using the log parser template for quite some time and found it very usefull to use. Infact we are using it in all of our log files to capture any error coming from our applications that we other wise wouldn't know about. What I would like to ask if its possible to use a regex to exclude some content coming from a particular ip? So not to send any unwanted alerts.

Thanks

Joseph
