kill a process if grep match is found

Hi,

I need something unusual, I guess. I need to start a process, and if that process displays a specific error message, I need to kill that process and restart it.

Something like:
Code:
startprocess | grep -i "This is the specific error message" && kill $pidof(startprocess)

Explanation, I need to start the process, check if it echoes any messages and if any of them is the one that I'm waiting, I need to kill that process.

Restarting of the process I can do putting all this in a while loop or something.

Is this possible at all? Is there any easier way to accomplish the same thing?

Thanks for any help in advance.

kill(1) 						      General Commands Manual							   kill(1)

Name
       kill - send a signal to a process

Syntax
       kill [-sig] processid...
       kill -l

Description
       The command sends the TERM (terminate, 15) signal to the specified processes.  If a signal name or number preceded by `-' is given as first
       argument, that signal is sent instead of terminate.  For further information, see

       The terminate signal kills processes that do not catch the signal; `kill -9 ...' is a sure kill, as the KILL (9) signal cannot  be  caught.
       By convention, if process number 0 is specified, all members in the process group (that is, processes resulting from the current login) are
       signaled.  This works only if you use and not if you use To kill a process it must either belong to you or you must be superuser.

       The process number of an asynchronous process started with `&' is reported by the shell.  Process numbers can also be  found  by  using	It
       allows job specifiers ``%...''  so process ID's are not as often used as arguments.  See for details.

Options
       -l   Lists  signal  names.  The signal names are listed by `kill -l', and are as given in /usr/include/signal.h, stripped of the common SIG
	    prefix.
