How to access data for IO structure?

Hi,

IO structure is as follows:- 

ListOf_ssServiceRequest
             ssServiceRequest
             ListOf_ssOrderEntryOrders 
                         ssOrderEntryOrders
                         ListOf_ssAction
                                     ssAction
                         ListOf_ssOrderEntryLineItems
                                     ssOrderEntryLineItems
                         ListOf_ssServiceCustomerSurvey
                                     ssServiceCustomerSurvey
                         ListOf_ssEautoServiceHistory 
                                      ssEautoServiceHistory
             ListOf_ssCustomerComplaint
                          ssCustomerComplaint

Problem is there is 1:m relationship between complaint and action.

Required format is:-
|complaint   | action1|
|complaint   | action2|
|complaint   | action3|

Now for each action to access complaint I need to use xpath because complaint is not direct parent in xml structure.
Any suggestion?

Thanks.
