An interesting question came up on the soaplite mailing list concerning how to modify the namespaces registered in the SOAP envelope. Documentation is not especially clear on this point.
Of course, a quick hack is to attach a full namespace to an element directly, as in:
SOAP::Data->name('itemName')->attr({'xmlns:mns' => 'http://my.namespace'})
With version SOAP::Lite 0.65 and above, the register_ns serializer method helps to correctly construct the envelope, as shown in the following example:
#!/usr/bin/perl -w
# $Id$
#
use strict;
#SOAP::serializer->register_ns requires 0.65
use SOAP::Lite 0.65 +trace => 'debug';
my $soap = SOAP::Lite
->proxy( 'http://localhost/blah/DummyService' );
my $serializer = $soap->serializer();
$serializer->register_ns( 'http://my.namespace', 'mns' );
my $som = $soap->call(
SOAP::Data
->name('mns:test')
=> SOAP::Data->name('mns:description' => 'an item in my namespace')->type('mns:mytype')
);
This generates the following SOAP request:
<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:mns="http://my.namespace"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
soap:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<mns:test>
<mns:description xsi:type="mns:mytype">an item in my namespace</mns:description>
</mns:test>
</soap:Body>
</soap:Envelope>
