in thread Why SOAP::Lite Method call returned partially XML formatted?

Hi there,

Here is a full sample of my code that calls the doSelect web service function. In the code sample I make a retrieveCategories subroutine call that prints the full result and valueof result. Notice, the full result is correctly displayed but valueof method does not return the value.

Here is my code sample

#!/usr/bin/perl -w

use SOAP::Lite trace=>'debug';
#use SOAP::Lite;
use Data::Dumper;
use strict;

# Perl sub routine to call Service Desk login method
# and specify Service Desk Web Services end point
sub login_get_SID {

    # Edit $server, $user and $pw as needed.
    my $server = '192.168.1.152:8180';
    my $endpoint = '/axis/services/USD_R11_WebService?WSDL';

    my $user = ''; #user id
    my $pw  = ''; #user pwd

    my $wsdl = 'http://' . $server . $endpoint;
    my $service = SOAP::Lite->service($wsdl);
    my $sid = $service->login($user, $pw);
    return ($service, $sid);
}

# Always a best practice to call logout() when done
sub logout {
    my ($service, $sid) = @_;
    $service->logout($sid)
}

# method to retrieve all Incident Areas
sub retrieveCategories
{
    my ($service, $sid, $service_name) = @_;
    my $method = SOAP::Data->uri('http://www.ca.com/UnicenterServicePl
+us/ServiceDesk')->name('doSelect');

    # Attributes for object to be created can be pulled
    # from majic files.
    my @params = (    SOAP::Data->name("sid" => $sid),
                    SOAP::Data->name("objectType" => 'pcat'),
                    SOAP::Data->name("whereClause" => "sym like 'Appl%
+'"),
                    SOAP::Data->name("maxRows" => "1"),
                    SOAP::Data->name("attributes" =>
                        \SOAP::Data->value(    
                         SOAP::Data->name("string" => "sym"),
                         SOAP::Data->name("string" => 'description')
                        )
                    ),
                  );

       #print "dumper: ".Dumper(@params)."\n";
    my $result = $service->call($method => @params);
    print "----result method call ---\n".$result->result."----- end re
+sult ----\n";
    print "----valueof method call ----\n".$result->valueof('//AttrNam
+e[1]')."----- end valueof ----\n";
    return ($result);
}

# Main calls
my ($service, $sid) = login_get_SID();
retrieveCategories($service, $sid);
logout($service, $sid);

Here is the output from retrieveCategories() subroutine:

    See Re^2: Why SOAP::Lite Method call returned partially XML formatted?

    That is exactly what you would expect to happen. It has nothing to do with SOAP::Lite serialization. Basically USD_R11_WebService (or whatever its called) double encoded some xml (stuffed an entire xml document into <doSelectReturn xmlns=""></doSelectReturn> ). The response (an xml document) doesn't contain any AttrNam elements.
