∟SOAP::Data - Utility Class to Generate XML Elements

This section provides a tutorial example on how to use the SOAP::Data class to generate the parameter element with the correct element name. The SOAP::Data class is a utility that allows you generated XML elements with correct name, attributes and sub elements.

I am sure you noticed the issue with the parameter element name, c-gensym3. The solution is easy as we learned from previous SOAP 1.1 tutorials. The SOAP::Data class can be used to generate parameters with correct element names:

   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', 
      SOAP::Data->name("ubiNum")
      ->value(102));

Result of NumberToWords_localhost_SOAP_Data.pl:
