You may find the answers to the rather similar question Oracle report converter posted by denzil_cactus helpful (oh, that was you too! Maybe not then).

Generally if we can't answer a question to your satisfaction the first time round we are unlikely to do much better on subsequent asking within a few days. Maybe you need to go back to the answers you have already and try to work out why they are not suitable for you. Let me give you a hint: the answers are good, but you have chosen a large and possibly difficult problem to tackle.
