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

Yes, it might help;) - I got the following:
Can't use string ("<?xml version="1.0" encoding="ut") as an ARRAY ref
while "strict refs" in use at /usr/local/share/perl/5.8.7/SOAP/Lite.pm
line 459.

Because its not a simple SOAP call and its easier for me to roll it
myself since that's how the person who wrote the service recommends
doing it. But it would be nice to get the response back where its easily
parsable.

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?
