How can I read a DataSet from WCF-Response ?

Hi, I’m facing a serious problem reading the response of a WCF-SQL call. The scenario is very simple.

I’m generating schemas in BT using the WCF-SQL wizard (for a SP I’ve written). Request schema and Response schemas are generated but I want to use xpath to read from the response. However my response schema contains a DataSet. How can I read from this? 

Ideally I would have a single repeating element instead of the DataSe but that doesn’t seem an option. Your help would be greatly appreciated!

Thanks
