Help linking sub reports to master report

[idrinkjava]

I just started using iReport 4.0.2 and am trying to iterate through a nested XML file.  I realize that this is probably elementary so excuse me if this is a stupid question.  From all of the information that I have read on the web, in order to get at the nested information, I need to create subreports that return that data.  I have a master report that pulls the header data and a subreport that gathers a list of data from one of these nested XML trees.  For each heading that I generate on the master form, I would like to display it's children, the items nested under it.  The problem that I am having is finding the correct way to link the forms together, i.e. telling the master form to display the information of the subreport on its page.  Any help would be appreciated and thanks in advance for your help.
