Not able to add Query_Match displatch style

Hi Team,

I am trying to add Query_Match dispatch style to me first virt created using sample services. When I am trying to test the Xpath added to my Query_Match error displayed as "Missing request to query"

Please can you guide me as to how to add dispatch style with some example.

Note: I am using Ready! API 1.2.1
