In XSL how do you group common child nodes and associa

I have a xml file as shown below

     <B>Test</B>
     <C>
          <CName>C1</CName>
          <D>
               <Dname>D1</DName>
               <Dname>D2</DName>
               <Dname>D3</DName>
          </D>
     </C>

     <B>Test</B>
     <C>
          <CName>C2</CName>
          <D>
               <Dname>D1</DName>
               <Dname>D4</DName>
          </D>
