I've been thinking more about this, and the complex
datastructures should pose no problem.  I did a little
looking around my Perl installation (including CPAN modules
RH shipped) and found XML::Dumper, which will take a Perl
structure and output XML.  Here's an example from the man
page:

#!/usr/bin/perl

# Convert Perl code to XML
use XML::Dumper;
my $dump =3D new XML::Dumper;
$data =3D [
          {
            first =3D> 'Jonathan',
            last =3D> 'Eisenzopf',
            email =3D> 'ei...@po...'
          },
          {
            first =3D> 'Larry',
            last =3D> 'Wall',
            email =3D> ' la...@wa...'
          }
         ];
$xml =3D $dump->pl2xml($data);

print $xml, "\n" ;

# EOF

Which produces:

<perldata>
 <array>
  <item key=3D"0">
   <hash>
    <item key=3D"last">Eisenzopf</item>
    <item key=3D"first">Jonathan</item>
    <item key=3D"email">ei...@po...</item>
   </hash>
  </item>
  <item key=3D"1">
   <hash>
    <item key=3D"last">Wall</item>
    <item key=3D"first">Larry</item>
    <item key=3D"email"> la...@wa...</item>
   </hash>
  </item>
 </array>
</perldata>
