[oXygen-user] xQueries in eXist

Hi, I tried to run xQueries in Oxygen, but in the Configure Transformation Scenario- Edit Scenario, I can't find the exist connection in the Transformer selection box. Does anyone know how to set it up? Or this is not available for The current Oxygen and eXist releases? Our catalogers create XML records, and need to search the Records by keyword or ID in exist. I created several Canned xQueries for them to run. My second question is, is it possible to create a Search button in Oxygen, which could embed our canned xQueries in it, so that Our catalogers can use it to search records in eXist? Thanks. Jenny
