Re: [hobbit] Some PCRE assistance

Yes, that is the format of the list.

I actually solved the problem another way, I always thought the heading 
line was superfluous in this case anyway.

This is for a procs test for the z/VM client that I'm writing.  In this 
case a dispatchable unit of work is a virtual machine, so the 'process' 
list contain the names of the virtual machines.  Well since it is just a 
list of names and not process numbers, CPU Time, command, etc, I just 
changed the back-end client code to not require the heading line coming 
from the client.

Thanks to all who responded.
