Nesting xsl templates and referring multiple templates to the same node?

问题

This is my first post :)

I'll try to be clear and nice, thank you in advance for any help! And I apologize that this question is convoluted. :| Any friendly hints on how to better ask the question will be appreciated too!

This is a reduced version of the xml source file I have:

        </ROW>
    </FMPDSORESULT>

This is the needed result xml structure (sorry the data is not the same, but the tag names mostly resemble):

As you can see, I have several issues:

I think I need to somehow nest the templates, but that doesn't give the desired result (the nested template wrongly shows up after the tag E1EDL20 has been closed). How can I do this properly?
What template match can I use for the 'array' data in the E1EDL44 tag?

That match problem with unique identifiers is, as clearly seen in the xsl a problem, because I have to nest this structure (I know I shouldn't do it, but I don't see how else to achieve this structure):

 <DELVRY05>
     <IDOC BEGIN="1">
         <EDI_DC40 SEGMENT="1">
             <!-- header data unique tags - template on first ROW -->
         </EDI_DC40>
         <E1EDL20 SEGMENT="1">
             <!-- more header data unique tags, this has to be done seperate, because of the container tag, I assume 2 nd template on the first ROW -->
             <E1EDL24 SEGMENT="1">
                 <!-- line data tags; random n, corresponds to the ROWS in the source file -->
             </E1EDL24>
             <E1EDL37 SEGMENT="1">
                 <!-- again header data unique tags -->
                 <E1EDL44 SEGMENT="1">
                     <!-- 'arrayed' data, random n lines, I don't even know how to do this one! It should also only appear one time, only for the first line ( so I thought this would need a third template on the first ROW  -->
                 </E1EDL44>
             </E1EDL37>
         </E1EDL20>
     </IDOC>
 </DELVRY05>

How do I get the E1EDL44 nested in there?

Please help me! Thank you very much for every tidbit of help you can offer or steer me in the right direction. Tom
