How to export hash to xml file

[Sombrerero_loco]

Hi monkers. I need to export a hash with the next structure to xml:

%index{$name}{"SID"} = value
      {"level"} = value
      {"service"} = value
      {array with values}

Im triying to do with xml::dumper but i feel like a nerd and i really dont know how i can do, because when i type use XML::Dumper, its takes the next line as the file (???) and told me it can't export it. This its the code that i suppuose i must use to export my hash to a xml file:

foreach $control_clase (keys (%clases)){                            
  if ($control_clase eq $index{$name}{"nivel"}) {                   
  		$index{$name}{"clase"} = $clases{$control_clase} }          
   }
}

Thanks!
