echo XMI313 | awk '/XMI[0-9][0-9][0-9]/ {print $0}'

this is a little neater:

echo XMI333 | awk '/XMI[0-9]+/ {print $0}'

but could have unanticipated consequences. For instance, if you do that 
with an input of something like 'XMI3334', its going to find that, but 
that's also true of the first example. (because the substring matched. 
That's probably ok for your purposes. If not, you might try anchoring 
that with a ^ and a $ if necessary (assuming that would work for your 
stream).
