Load Test XML responses

Hi, there recently I tried SoapUI testing program to test site for xml bombs etc and it was really helpful. Thanks for that.

This time I have task to test sites load and requests. What I did is created test request with XML validation, and I need to test it on load. I created LoadTest and there I'm sending this xml for 60 seconds. SoapUI log shows it nicely - status 200 all going, but thing I need is to check on all of those successfully returned XMLs during 60 seconds. How to configure SoapUI to do that?

Thanks in advance
