c++ - Traversing through a class object list and printing it out -

i have class object structure shown below. here place names objects of class x , bank names objects of class y.

<midwest>    <independent bank of midwest/>    <midland bank of america/>    <texas>       <bank of america/>       <chase bank/>       <wells fargo/>       <austin>          <supereme national bank/>          <master chanse bank/>          <austin east>             <national bank of austin/>             <federal bank/>          </austin east>       </austin>     </texas>    <arizona></arizona>    <kansas>       <federal credit union/>       <kansas state bank/>       <wichita>          <state bank of kansas/>          <wichita credit union/>       </wichita>    </kansas>    <missouri>       <bank of st louis/>    </missouri>    <kentucky></kentucky>    <iowa></iowa> </midwest> 

what want is, traverse parent (midwest) object , go through each child element , print out. trick here is, there can multiple class x objects inside class x object itself.

i couldn't come smart logic loop through , find child elements , print out. above object structure example. in application combination of places , banks , logic should smart enough traverse root parent down each child element.
