Obtaining both XML and parsed object from SOAP::Lite?

[vitoco]

I need to work with the result of a SOAP::Lite call, but I must also save the original XML from the response as a backup. Is there a standard method that could replace the last line from the following code?

my $soap = SOAP::Lite->new( proxy => 'http://mywebservice/');
my $som = $soap->call(
  'MyMethod',
  SOAP::Data->name(MyArg => 'XYZ')
);
die $som->faultstring if ($som->fault);

#print Dumper($som->result);

my @nodes = $som->valueof('//Path/To/Data');
foreach my $node (@nodes)
{
  print Dumper($node);
}

#print Dumper($som);

print Dumper($som->{_context}->{_transport}->{_proxy}->{_http_response
+}->{_content});

Note: this code have been snipped just to show what I want to do...
