I found using groovy's native xml processing abilities much more faster and flexible in whatever you want to achieve while parsing response and generating request from the response. It is also easier than using xmlHolder. I had difficulties using xmlHolder where I need to pull node from response and add to next request. I simply could not do it. Plus add more confusion with namespaces for response being inconsistent with those for the request that you want to create. Using groovy you can totally define namespaces for generated request and even for each gpathresult
hope this helps
