using SOAP::SOM to parse a LWP::UserAgent response

Hi,

I have a LWP::UserAgent request that I want the response to become a 
SOAP::SOM object. Is this possible?

I've tried the following but got a weird SOAP/Lite error:

$response = $ua->request($request);
$som = SOAP::SOM->new($response->content());
print $som->valueof('//Result/Data');

Any suggestions?

TIA

Justin
