XSLT Help Request - Building Hierarchy

Question

Hi everyone,
We are receiving a file that has the following structure, where fields that start with H are header fields, and fields that start with D are detail fields (like a header and line items in an FI posting).
H1, H2, H3, D1, D2, D3, D4, D5
On the first line of the FI posting, the H and the D fields are populated (i.e. contains the header information, and the first line item information).  Then on the next lines, the H fields are all blank, and the D fields are populated.  So like this:
H1, H2, H3, D1, D2, D3, D4 (for line item 1)
, , ,D1, D2, D3, D4 (for line item 2)
The file can also have more than 1 FI posting (i.e. more than 1 Header):
H1, H2, H3, D1, D2, D3, D4 (for line item 1)
, , ,D1, D2, D3, D4 (for line item 2)
H1, H2, H3, D1, D2, D3, D4 (for line item 1)
, , ,D1, D2, D3, D4 (for line item 2)
We are trying to map this into a FIDCC1 idoc posting, which looks like this:
<FIDCCP01>
  <IDOC>
    <Header>
      <H1></H1>
      <H2></H2>
      <H3></H3>
      <Item><D1></D1><D2></D2><D3></D3><D4></D4></Item>
      <Item><D1></D1><D2></D2><D3></D3><D4></D4></Item>
    </Header>
  </IDOC>
  <IDOC>
    <Header>
      <H1></H1>
      <H2></H2>
      <H3></H3>
      <Item><D1></D1><D2></D2><D3></D3><D4></D4></Item>
      <Item><D1></D1><D2></D2><D3></D3><D4></D4></Item>
    </Header>
  </IDOC>
</FIDCCP01>    
We can't make this work alone in the concent conversion, so was thinking that this could be done in XSLT.  We have created a data type that contains the fill H and D fields and are taking this into XI no problems, but we are having problems putting it into the hierarchy.  Any help is greatly appreciated.
Thanks

Here is the input file, top line being the field breakdown
12222333333334444566666666666666667777777777777777
1FB0104052007ARP 20000000026590.000000000000000.00
/////////////////20000000098765.000000000000000.00
1FB0104052007USD 20000000012345.000000000000000.00
/////////////////20000000054321.000000000000000.00
Field 1, when it is a "1", is the start of the header line.  Field 5 will always be a "2", and is the start of the detail line.  Also all null fields are populated with a slash.
My idea was to take this in all on 1 line where the structure contains both the header and the detail fields, because I wasn't sure if content conversion could do what I wanted.  When I do that, here is the result:
<?xml version="1.0" encoding="utf-8"?>
<ns:IFS_MT xmlns:ns="http://xx.com/xi/fin/gl/iams/ifs">
     <Detail>
          <STYPE1>1</STYPE1>

          <WAERS>ARP</WAERS>

     </Detail>     
</ns:IFS_MT>
I am open to changing the file content conversion if there is a better way!
The desired result is:
<FIDCCP01>
     <IDOC>
          <E1FIKPF>
               <TCODE>FB01</TDOCE>
               <BLDAT>04052007</BLDAT>
               <WAERS>ARP</WAERS>
               <E1FISEG>
                    <WRBTR>0000000026590.00</WRBTR>
                    <DMBE2>0000000000000.00</DMBE2>
               </E1FISEG>
               <E1FISEG>
                    <WRBTR>0000000098765.00</WRBTR>
                    <DMBE2>0000000000000.00</DMBE2>
               </E1FISEG>
          </E1FIKPF>

</FIDCCP01>
Thanks again!
