default_ns() - Setting Namespace for Body Elements

This section provides a tutorial example on how to set Body sub elements under a default namespace of any specified URI - Using the default_ns() function.

The next issue is to set a default namespace of "http://www.dataaccess.com/webservicesserver/" as required by the NumberToWords Web service document. I used the following test program to test the default_ns() function:

#- NumberToWords_localhost_default_ns.pl
#- Copyright (c) 2009 HerongYang.com. All Rights Reserved.
#
   use SOAP::Lite +trace;
   my $client = SOAP::Lite->new()
      ->soapversion('1.2')
      ->envprefix('soap12')
      ->default_ns('http://www.dataaccess.com/webservicesserver/')
      ->readable(true)
      ->proxy('http://localhost/NumberConversion.wso');

   my $som = $client->call('NumberToWords', 102);

Result of NumberToWords_localhost_default_ns.pl:

POST http://localhost/NumberConversion.wso HTTP/1.1
Accept: text/xml
Accept: multipart/*
Accept: application/soap
Content-Length: 615
Content-Type: application/soap+xml; charset=utf-8
SOAPAction: "http://www.dataaccess.com/webservicesserver/#NumberToWords"

<?xml version="1.0" encoding="UTF-8"?>
<soap12:Envelope
    soap:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
    xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
    xmlns:soap12="http://www.w3.org/2003/05/soap-envelope"
    xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <soap12:Body>
    <NumberToWords xmlns="http://www.dataaccess.com/webservicesserver/">
      <c-gensym3 xsi:type="xsd:int">102</c-gensym3>
    </NumberToWords>
  </soap12:Body>
</soap12:Envelope>

The result looks very good. default_ns() did set the NumberToWords element under the default namespace of the specified URI.

Notice that the default namespace URI also used by the SOAPAction header line.
