=head1 NAME

SOAP::WSDL::Client - SOAP::WSDL's SOAP Client


 use SOAP::WSDL::Client;
 my $soap = SOAP::WSDL::Client->new({
     proxy => ''
 $soap->call( \%method, $body, $header);

=head1 METHODS

=head2 call

 $soap->call( \%method, \@parts );

%method is a hash with the following keys:

 Name           Description
 operation      operation name
 soap_action    SOAPAction HTTP header to use
 style          Operation style. One of (document|rpc)
 use            SOAP body encoding. One of (literal|encoded)

The style and use keys have no influence yet.

@parts is a list containing the elements of the message parts.

For backward compatibility, call may also be called as below:

 $soap->call( $method, \@parts );

In this case, $method is the SOAP operation name, and the SOAPAction header
is guessed from the first part's namespace and the operation name (which is
mostly correct, but may fail). Operation style and body encoding are assumed to
be document/literal

=head2 Configuration methods

=head3 outputxml


When set, call() returns the raw XML of the SOAP Envelope.

=head3 set_content_type

 $soap->set_content_type('application/xml; charset: utf8');

Sets the content type and character encoding.

You probably should not use a character encoding different from utf8:
SOAP::WSDL::Client will not convert the request into a different encoding

To leave out the encoding, just set the content type without appending charset
like this:



 text/xml; charset: utf8

=head3 set_prefix


If set, alters the serialization of the request XML such that the supplied value is used as a namespace prefix for SOAP method calls. By way of example, the default XML serialization returns something like this:

    <?xml version="1.0"?>
        <getElementId xmlns="">

If the sample set_prefix() call above is used prior to calling your SOAP method, the XML serialization returns this instead:

    <?xml version="1.0"?>

This is useful in cases where, for instance, one is communicating with a JAX L<> webservice, which tends to understand the latter but not the former. Note that this implementation is currently limited to a single additional namespace; if you require multiple custom namespaces, you should probably look into creating your own serializer.

=head2 Features different from SOAP::Lite

SOAP::WSDL does not aim to be a complete replacement for SOAP::Lite - the
SOAP::Lite module has its strengths and weaknesses and SOAP::WSDL is
designed as a cure for the weakness of little WSDL support - nothing more,
nothing less.

Nonetheless SOAP::WSDL mimics part of SOAP::Lite's API and behaviour,
so SOAP::Lite users can switch without looking up every method call in the

A few things are quite different from SOAP::Lite, though:

=head3 SOAP request data

SOAP request data may either be given as message object, or as a hash ref (in
which case it will automatically be encoded into a message object).

=head3 Return values

The result from call() is not a SOAP::SOM object, but a message object.

Message objects' classes may be generated from WSDL definitions automatically
- see SOAP::WSDL::Generator::Typelib on how to generate your own WSDL based
message class library.

=head3 Fault handling

SOAP::WSDL::Client returns a fault object on errors, even on transport layer

The fault object is a SOAP1.1 fault object of the following

SOAP::WSDL::SOAP::Typelib::Fault11 objects are false in boolean context, so
you can just do something like:

 my $result = $soap->call($method, $data);

 if ($result) {
    # handle result
 else {
    die $result->faultstring();

=head3 outputxml

SOAP::Lite returns only the content of the SOAP body when outputxml is set
to true. SOAP::WSDL::Client returns the complete XML response.

=head3 Auto-Dispatching

SOAP::WSDL::Client B<does not> support auto-dispatching.

This is on purpose: You may easily create interface classes by using
SOAP::WSDL::Client and implementing something like

 sub mySoapMethod {
     my $self = shift;
     $soap_wsdl_client->call( mySoapMethod, @_);

You may even do this in a class factory - see L<> for creating
such interfaces.


=head2 Accessing protected web services

Accessing protected web services is very specific for the transport
backend used.

In general, you may pass additional arguments to the set_proxy method (or
a list ref of the web service address and any additional arguments to the
new method's I<proxy> argument).

Refer to the appropriate transport module for documentation.
