Soap Lite - raw XML passed to function

Hello

I wrote web service using library SOAP Lite

SOAP::Transport::HTTP::CGI->dispatch_to(MyModule)->handle;
package MyModule;
sub my_method {
my $class = shift;
my @rgs = @_;
}

In @args I would like to get raw XML with paramters from client.
But I always get parssed values.
I've found method xmloutput('true') but probably I've used it wrongly
because there are always parssed values, not XML. I was not able
to find example using xmloutput('true').

Have you any idea?

Greetings

Marcin
