fritz1968 has asked for the wisdom of the Perl Monks concerning the following question:

I have (mostly) figured out soap::lite. However, I cannot tell anyone as it is a closely guarded secret. ;-)

I say mostly, as I want to generate a document that will have multiple request in it. Take the following code for example: 

sub release {
    my ($args) = @_;
        # IIS web services expect / as a separator for uri and method.
    my $lite = SOAP::Lite->new()->on_action(sub { join '/', @_ } )
        ->proxy($args->{proxy}),
           SOAP::Header->name('Authentication' =>
                   SOAP::Header->value(
                         SOAP::Header->name('user')->value($zID),
                         SOAP::Header->name('password')->value($zPW)))
+;

        my $response = $lite->call(
           SOAP::Data->name('release')
           ->attr({ 'xmlns', $args->{xmlns}}),
                   SOAP::Data->name('request' => \SOAP::Data->value(
                   SOAP::Data->name('actionTime')->value($args->{actio
+nTime}),
                   SOAP::Data->name('id')->value($args->{id})->type('l
+ong'),
                   SOAP::Data->name('state')->value($args->{state})->t
+ype('string'),
                   SOAP::Data->name('result')->value($args->{result})-
+>type('string')
                   )),
            );
    return $response;
}

This will generate the following XML document:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envel
+ope/" xmlns:ns="http://myid.somecompany.net/request/service/3">
   <soapenv:Header/>
   <soapenv:Body>
      <ns:release>
         <ns:request>
            <ns:id>4161</ns:id>
            <ns:actionTime>2012-09-25T13:26:43.000Z</ns:actionTime>
            <ns:state>PLACED</ns:state>
            <ns:result>ACTION_TAKEN</ns:result>
         </ns:request>
      </ns:release>
   </soapenv:Body>
</soapenv:Envelope>

My next task is to create an XML document that generated multiple "requests." For example, the following: 

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envel
+ope/" xmlns:ns="http://myid.somecompany.net/request/service/3">
   <soapenv:Header/>
   <soapenv:Body>
      <ns:release>
         <ns:request>
            <ns:id>4161</ns:id>
            <ns:actionTime>2012-09-25T13:26:43.000Z</ns:actionTime>
            <ns:state>PLACED</ns:state>
            <ns:result>ACTION_TAKEN</ns:result>
         </ns:request>
         <ns:request>
            <ns:id>4162</ns:id>
            <ns:actionTime>2012-09-25T13:26:44.000Z</ns:actionTime>
            <ns:state>PLACED</ns:state>
            <ns:result>ACTION_TAKEN</ns:result>
         </ns:request>
      </ns:release>
   </soapenv:Body>
</soapenv:Envelope>

I know the magic has to happen in this section of the code:

        my $response = $lite->call(
           SOAP::Data->name('release')
           ->attr({ 'xmlns', $args->{xmlns}}),
                   SOAP::Data->name('request' => \SOAP::Data->value(
                   SOAP::Data->name('actionTime')->value($args->{actio
+nTime}),
                   SOAP::Data->name('id')->value($args->{id})->type('l
+ong'),
                   SOAP::Data->name('state')->value($args->{state})->t
+ype('string'),
                   SOAP::Data->name('result')->value($args->{result})-
+>type('string')
                   )),
            );

but the question is how? a loop of some sort is, obviously, needed. But where to I put it? The variable that I am using to store the data is an array of hashes. In the above code, I am simply passing a single hash. However, I can always pass the array of hashes.

any help, suggestions, ideas would be appreciated. Thanks, Frank

Re: More Soap::Lite

    I have (mostly) figured out soap::lite. ... but the question is how? a loop of some sort is, obviously, needed. But where to I put it? 

    #!/usr/bin/perl --
use SOAP::Lite;
my $soap = SOAP::Lite->proxy(
    'http://localhost/blah/DummyService',
    timeout => 0.00001,
);

$soap->transport->add_handler("request_send",  \&pp_dump );

my $serializer = $soap->serializer();


my @data = (

    SOAP::Data->name(
        'request' => \SOAP::Data->value(
            SOAP::Data->name('actionTime')->value('actionTime'),
            SOAP::Data->name('id')->value('id')->type('long'),
            SOAP::Data->name('state')->value('state')->type('string'),
            SOAP::Data->name('result')->value('result')->type('string'
+)
        )
    ),
    SOAP::Data->name(
        'request' => \SOAP::Data->value(
            SOAP::Data->name('actionTime')->value('actionTime'),
            SOAP::Data->name('id')->value('id')->type('long'),
            SOAP::Data->name('state')->value('state')->type('string'),
            SOAP::Data->name('result')->value('result')->type('string'
+)
        )
    ),
);

print pp(
    $serializer->envelope(
        method => SOAP::Data->name('release')->attr( { 'xmlns', 'ns' }
+ ),
        @data,
    ),
);

$soap->call(
    SOAP::Data->name('release')->attr( { 'xmlns', 'ns' } ),
    @data,
);

 
sub pp {
    use XML::Twig;
    open my($fh), '>', \my $str;
    no warnings 'newline';
    XML::Twig->new(
        qw! pretty_print record !
    )->parse(
        @_
    )->print( $fh );
    return $str;
}

sub pp_dump {
    {
        my $content = $_[0]->content('');
        $_[0]->content( pp($content) );
    }
    print $_[0]->as_string,"\n";
    return;
}

      Thanks for the code. I modeled my code after yours and came up with the following:

          foreach $rHash (@userData)
    {
    my $tempString = ();
    $tempString=SOAP::Data->name('request' => \SOAP::Data->value(
              SOAP::Data->name('actionTime')->value($zTime),
          SOAP::Data->name('id')->value($id1)->type('long'),
          SOAP::Data->name('state')->value($state1)->type('string'),
          SOAP::Data->name('result')->value($result1)->type('string')
        ));
    push(@soapArray, $tempString);
    }# end foreach

    my $release_response = release($proxy, $xmlns, @soapArray);

      [download]

      Before the above code is executed, the user Data is retrieved from a WSDL and stored in an array - @userData - of hashes. That array of hashes is ran through a foreach loop to dynamically format each record to a string ($tempString) and then to add that string to an array (@soapArray). Then I call a subroutine and pass the necessary information to execute the WSDL call:
      my $release_response = release($proxy, $xmlns, @soapArray);

      In the subroutine, I make the WSDL call: 

          my ($proxy1, $xmlns1, @array1) = @_;
        # IIS web services expect / as a separator for uri and method.
    my $lite = SOAP::Lite->new()->on_action(sub { join '/', @_ } )
    ->proxy($proxy1),
           SOAP::Header->name('Authentication' =>
               SOAP::Header->value(
             SOAP::Header->name('user')->value($zID),
                 SOAP::Header->name('password')->value($zPW)));
    
    
    my $response = $lite->call(
       SOAP::Data->name('release')
       ->attr({ 'xmlns', $xmlns1}), @array1 );

    return $response;

      [download]

      The name of the array changes in the subroutine from @soapArray to @array1.

      Again, thanks for the help. It is much appreciated.
      Frank
