Transformation problems..

If I have an xml document that looks like this:

<Top>
    <Child>
        <SomeElement />
        <AChildRecord><Data></Data><MoreData></MoreData><AChildRecord>
        <SomeOtherElement />
   </Child> 
    <Child>
        <SomeElement />
        <AChildRecord><Data></Data><MoreData></MoreData><AChildRecord>
        <SomeOtherElement />
   </Child>
</Top>

My problem is that the <AChildRecord> is the same for all <Child> record. But I only want to map it once. E.g you get something like this:

MappedAChildRecord
MappedChild1
MappedChild2
MappedChild3.. 

Not like this (the way I get it now):

MappedAChildRecord
MappedAChildRecord
MappedAChildRecord
MappedChild1
MappedChild2
MappedChild3..

 I don't know if I'm explaining this well enough. But basically in the xml format I want to transform to <Child> and <AChildRecord> are sibblings. And since I know AChildRecord will be the same for ALL <Child> I only want it once, while I want all of the <Child> tags. Does that make sense?
