This isn't quite what you are looking for either, but...

One interesting approach would be to have a Data::Dumper like functionality that would output in XML format. Does anyone know if there is a moule out there that does this?

$f{foo}=[{a=>5,b=>7},{a=>1,b=>2}];
print DumperXML(\%f);
[download]

would print something like

<foo> 
  <element>
    <a>5</a>
    <b>7</b>
  </element>
  <element>
    <a>1</a>
    <b>2</b>
  </element>
</foo>
[download]

or something like that....
