How to create a Notification which required specific formatted response

Question

Hi,
I'd like ask about the notification.
In the Workflow guide, there are some documentations about the templated message.
I mean that there is a response instructions that should be obeyed in order to get the right action.
I found in the System: Mailer.
There are many example of messages such as
- Orig. Workflow Open Mail (Direct)
- Orig. Workflow Open Mail (Templated)
Those messages' body said about a formatted response, such as
To submit your response, reply to this message, including this note with your reply.
The first lines of your reply must be your responses to the notification questions.
Instructions below detail exactly what should be placed on each line of your reply.
My questions are :
1. What should I do to create a notification such like that?
I mean, how to parse the message and then said to the Workflow Engine about what
will happen based on the respond received?
Since there will be some lookup codes in my workflow definition.
As far as I know, the Message (in Workflow Builder) is only use to specify the
notification's text.
2. Should I use a custom PL/SQL to parse each statement from the response?
Is there any example about how to use the PL/SQL (perhaps how to parse)?
3. Or is it automatically processed by the Workflow if I used the message provided by
the System: Mailer?
4. What if I'd like to make my custom message (instead of using the System: Mailer's
messages)?
Where should I put (or define) my PL/SQL code ?
Perhaps the response should look like this
The first line should be "Yes" or "No"
The second line should be the reasons with maximum length of 100 characters.
5. How to handle if the response is not exactly fullfil the instructions specified in the
message body?
Will there be errors?
Or the Workflow will stop running?
Or the Workflow will wait until the exact response is received?
6. I'd like to know if there is any example of it.
Perhaps, anybody has ever successed to meet these reqiurement.
Many thanks,
Buntoro

Hi,
Thanks Luiz, for the reply.
If I use lookup code, the response will look like in the Worklist of the Workflow Monitor, using some buttons to send the respon. And the button I clicked will determine which path the Workflow will run.
My requirement is the response is using an e-mail (not by clicking any button).
So the Approver should reply the notifications by writing and sending an e-mail, and the text body should look like the requirement I need.
i.e.
The first line of the response (in e-mail) should "Yes" or "No"
The second line is the reason of approving.
So how could I read the e-mail sent, extract it line by line, and inform the Workflow which path should be run.
If the first line of the e-mail is "Yes" then the Workflow will choose the "Yes" path.
else the Workflow will choose the "No" path.
Thanks,
