Extract pirority from an email

Hi

Exuse me if it was already asked, but I didn’t find the information. I
wonder if there is a scrip available wich will “read” the priority out a
a email. Here we use a template to send request, so every ticket
received by RT are similar.

example:

Name: John Smith

Priority : 1

Problem : …

I want to get the “1” and replace the default priority. Is it possible?

Thank you
