The SOAP::Lite module has a call valueof for complex structures. See Other reference.

Supose this code:

use strict;
use Data::Dumper;
 my $Call = 'f2c'.
 my $Result = $soap->call( $Call, 32 );

  if ( $Result->fault ) {
        printf "Failure on call: %s\n\t  Code: %s\nString: %s\n\n",
                $Call, $Result->faultcode, $Result->faultstring;
  }
  print Dumper( $Result->valueof('//' . $Call . 'Response') );
