Need to parse IIS logs with powershell?

I'm looking for a way to point powershell to the c:\iis directory to parse through iis logs and only output information to the screen that matches certain criteria.  I know is is a very broad question but anyone got any insight on how I could start?

would I use get-file or get-content?  Or either?

O would need something like get-content path to contect | where {item matches xxxxxx}

Any thoughts?  Thx
