Filter echo results from batch file output

Hey Experts.  I have a small batch file that outputs the results of pslist (processes running on computer) into a log file.  The output is great but I'm wanting to exclude certain things from ending up in the log file.  How do I control what is echo'd or parse the results in the log file?  Here is a small sample of what is in the log file:

I'd like to filter out the "svchost" and "chrome" results.  I'm aware that there might be Powershell options but I'd like to keep the batch file.  Thanks for your help.
