Wireshark-users: [Wireshark-users] Alert on captured packet

I have a protocol, where the same request is sent again and again. Suddenly 
a request is answered with another reponse as it done usually. I have 
configured Wireshark to use multiple files to capture all the data.

Now I want to get an alert (message box, email, anything else) when this 
event occurs. This can be done by manually look in each capture file. But 
this is a bit cumbersome. Can this be done with Wireshark tools or with an 
plug-in? Probably a LUA plug-in could do this?

The creteria for the alert should be something like
  udp.length > 1034 and udp.length< 1037


Thanks,
Harper
