NAME

XML::Compile::WSDL11 - create SOAP messages defined by WSDL 1.1

INHERITANCE

XML::Compile::WSDL11
  is a XML::Compile

SYNOPSIS

# preparation
my $wsdl    = XML::Compile::WSDL11->new($xml);
$wsdl->addWSDL(...additional WSDL file...);
$wsdl->importDefinitions(...more schemas...);

my $call    = $wsdl->prepareClient('GetStockPrice');

my $op      = $wsdl->operation('GetStockPrice');
my $call    = $op->prepareClient;

my $anwer   = $call->(%request);
my ($anwer, $trace) = $call->(%request);

my @op_defs = $wsdl->operations;

# Install XML::Compile::SOAP::Daemon
my $server  = XML::Compile::SOAP::HTTPDaemon->new;
$server->actionsFromWSDL($wsdl);

DESCRIPTION

This module is UNDER CONSTRUCTION. Missing: pure HTTP GET/POST bindings, multipart-mime; XML-RPC

An WSDL file defines a set of schemas and how to use the defined types using SOAP connections. The parsing is based on the WSDL schema.

The WSDL definition can get constructed from multiple XML trees, each added with addWSDL() (wsdl), or importDefinitions() (schema).

METHODS

Constructors

XML::Compile::WSDL11->new(XML, OPTIONS)

    The XML is the WSDL file, which is anything accepted by XML::Compile::dataToXML(). All options are also passed to create an internal XML::Compile::Schema object. See XML::Compile::Schema::new()

    Option        --Defined in     --Default
schema_dirs     XML::Compile     undef
wsdl_namespace                   undef

    . schema_dirs => DIRECTORY|ARRAY-OF-DIRECTORIES

    . wsdl_namespace => IRI

      Force to accept only WSDL descriptions which are in this namespace. If not specified, the name-space is enforced which is found in the first WSDL document.

Accessors

$obj->addSchemaDirs(DIRECTORIES)

XML::Compile::WSDL11->addSchemaDirs(DIRECTORIES)

$obj->findSchemaFile(FILENAME)

$obj->knownNamespace(NAMESPACE|PAIRS)

XML::Compile::WSDL11->knownNamespace(NAMESPACE|PAIRS)

$obj->schemas

$obj->wsdlNamespace([NAMESPACE])

    Returns (optionally after setting) the namespace used by the WSDL specification. This is the namespace in which the definition document root element is defined.

Read XML

$obj->dataToXML(NODE|REF-XML-STRING|XML-STRING|FILENAME|KNOWN)

Filters

$obj->walkTree(NODE, CODE)

Extension

$obj->addWSDL(XMLDATA)

    Some XMLDATA, accepted by XML::Compile::dataToXML() is provided, which should represent the top-level of a (partial) WSDL document. The specification can be spread over multiple files, which each have a definition root element.

$obj->importDefinitions(XMLDATA, OPTIONS)

    Add schema information to the WSDL interface knowledge. This should not be needed, because WSDL definitions must be self-contained.

$obj->namesFor(CLASS)

    Returns the list of names available for a certain definition CLASS in the WSDL.

$obj->operation([NAME], OPTIONS)

    Collect all information for a certain operation. Returned is an XML::Compile::WSDL11::Operation object.

    An operation is defined by a service name, a port, some bindings, and an operation name, which can be specified explicitly or sometimes left-out.

    When not specified explicitly via OPTIONS, each of the CLASSes are only permitted to have exactly one definition. Otherwise, you must make a choice explicitly. There is a very good reason to be not too flexible in this area: developers need to be aware when there are choices, where some flexibility is required.

    Option   --Default
operation  <required>
port       <only when just one>
service    <only when just one>

    . operation => NAME

      Ignored when the parameter list starts with a NAME (which is an alternative for this option). Optional when there is only one operation defined within the portType.

    . port => NAME

      Required when more than one port is defined.

    . service => QNAME

      Required when more than one service is defined.

$obj->prepareClient([NAME], OPTIONS)

Inspection

All of the following methods are usually NOT meant for end-users. End-users should stick to the operation() and prepareClient() methods.

$obj->find(CLASS, [QNAME])

    With a QNAME, the HASH which contains the parsed XML information from the WSDL template for that CLASS-NAME combination is returned. When the NAME is not found, an error is produced.

    Without QNAME in SCALAR context, there may only be one such name defined otherwise an error is produced. In LIST context, all definitions in CLASS are returned.

$obj->index([CLASS, [QNAME]])

    With a CLASS and QNAME, it returns one WSDL definition HASH or undef. Returns the index for the CLASS group of names as HASH. When no CLASS is specified, a HASH of HASHes is returned with the CLASSes on the top-level.

$obj->operations(OPTIONS)

    Return a list with all operations defined in the WSDL.

    Option --Default
produce  'HASHES'

    . produce => 'OBJECTS'|'HASHES'

      By default, this function will return a list of HASHes, each representing one defined operation. When this option is set, those HASHes are immediately used to create XML::Compile::WSDL11::Operation objects per operation.

DETAILS

Comparison

Initializing SOAP operations via WSDL

When you have a WSDL file, then SOAP is simple. If there is no such file at hand, then it is still possible to use SOAP. See the DETAILS chapter in XML::Compile::SOAP.

The WSDL file contains operations, which can be addressed by name. In this WSDL file, you need to find the name of the port to be used. In most cases, the WSDL has only one service, one port, one binding, and one portType and those names can therefore be omitted. If there is a choice, then you are required to select one explicitly.

use XML::Compile::WSDL11 ();

# once in your program
my $wsdl   = XML::Compile::WSDL11->new('def.wsdl');

# once for each of the defined operations
my $call   = $wsdl->prepareClient('GetStockPrice');

# see XML::Compile::SOAP chapter DETAILS about call params
my $answer = $call->(%request);

DIAGNOSTICS

Error: cannot find pre-installed name-space files

    Use $ENV{SCHEMA_LOCATION} or new(schema_dirs) to express location of installed name-space files, which came with the XML::Compile distribution package.

Error: don't known how to interpret XML data
