How to do for having standard responses in XML-RPC

[eluser]WebMada[/eluser]
Hello!

I am testing XML-RPC with CodeIgniter!
The examples given in the user guide and in the net always re:

Code:

if ( ! $this->xmlrpc->send_request())
        {
            echo $this->xmlrpc->display_error();
        }
        else
        {
            echo '<pre>';
            print_r($this->xmlrpc->display_response());
            echo '</pre>';
        }

Or in reality, we don't just display response but we treat it!
Are there examples that you can give me? Have I to parse the XML response?
