Well, my version of SOAP::Lite (0.67) is different than yours, so that
line number isn't helping me, but...

This from the SOAP::SOM manual page:

       Objects from the SOAP::SOM class aren't generally instantiated directly
       by an application. Rather, they are handed back by the deserialization
       of a message. In other words, developers will almost never do this:

           $som = SOAP::SOM->new;

       SOAP::SOM objects are returned by a SOAP::Lite call in a client con-
       text. For example:

           my $client = SOAP::Lite
               ->readable(1)
               ->uri($NS)
               ->proxy($HOST)
           $som = $client->someMethod();

This seems to indicate that you are approaching the problem wrong.  But...

If you really must, the same manual page seems to indicate that you
need to call match() before calling valueof().

I've never done what you are attempting because I've never had the
need.  So I have probably not helped much.  I still think you need to
just call the service directly with SOAP::Lite.  You might be
pleasantly surprised.

Huh?
