Comparing two xml documents from different web services

We'd like to setup a simple testing routine to detect changes to the xml returned by web services during development.

Our plan is to provide soapUI with two lists of urls. One for production & another for testing. Similar to below:

Test # Dev URL StableURL
1 http://dev01/service1.cfc http://stable/service1.cfc
2 http://dev01/service2.cfc http://stable/service2.cfc

soapUI would run through the list and compare the xml document received by each service. Alerting us if there are any differences between the dev url and production url.

Is this something soapUI would be good at? If so any quickstart documents or videos you could point me to on creating this type of configuration?

Thanks!
