NAME ^

XML::SRS - Shared Registry System XML Protocol

SYNOPSIS ^

 # Construct a request
 my $create = XML::SRS::Domain::Create->new(
          action_id => "kaihoro.co.nz-create-".time(),
          domain_name => "kaihoro.co.nz",
          term => 12,
          delegate => 1,
          contact_registrant => {
               name => "Lord Crumb",
               email => 'kaihoro.takeaways@gmail.com',
               address => {
                    address1 => "57 Mount Pleasant St",
                    address2 => "Burbia",
                    city => "Kaihoro",
                    region => "Nelson",
                    cc => "NZ",

  my $request = XML::SRS::Request->new(
      registrar_id => 555,
      requests => [$create],
  );

  my $xml_request = $request->to_xml;
  
  # $xml_request is now an XML string containing a request that can be sent to 
  # the SRS
  
  # $xml_response is an XML string recieved from the SRS
  my $response = XML::SRS::Response->parse($xml_response);
  
  # Calling 'results' gives us an array reference with the results for 
  #  each of the requests we sent. 
  my $results = $response->results;
  
  # Assuming the first result was a domain create, check to see if it was
  #  successful
  my $result = $results->[0]; # $result is a XML::SRS::Result
  
  my $domain = $result->response;
  
  # Print the domain's status
  print $domain->status;

DESCRIPTION ^

This module is an implementation of the XML protocol used by the .nz registry. It allows XML requests (and responses) to be constructed via an OO interface. Additionally, it allows SRS XML documents to be parsed, returning a set of objects.

Note, this documentation does not attempt to describe the SRS protocol itself. Please see the NZRS website (http://nzrs.net.nz) for more information on the protocol.

Validation is performed on both XML emitting and parsing. This should be less stringent than the SRS itself, so although XML::SRS may generate requests that the SRS will reject as invalid, you can be sure it won't reject input the SRS would accept.

The parsing and emitting of XML is handled by PRANG.

Some more information on how to create and parse XML documents follows. We assume that you're using XML::SRS from a client's point-of-view, i.e. you're interested in creating requests and parsing responses. Therefore, we don't discuss parsing requests and creating responses, even though XML:SRS has these capabilities.

Constructing requests

A request consists of multiple 'actions' or 'transactions', such as Whois, DomainCreate, etc. Each action has its own class in the XML::SRS namespace. These should be instantiated (see each individual class for information on the parameters for the constructor), and passed to the 'requests' parameter of a XML::SRS::Request object. The example in the synopsis illustrates the construction of a DomainCreate request.

You can then call the to_xml() method on the constructed object to retrieve the xml. Note, to_xml() can be called on any level of object if you require an XML fragment.

Parsing responses

A response can be parsed by simply calling the 'parse' method (or a related method - see below) on the XML::SRS package. Again, the synopsis of this module demostrates this.

The resulting object will be an XML::SRS::Response instance. See the documentation for that module for methods to retrieve the data in the response.

METHODS ^

This module uses the PRANG::Graph role, and so the parse methods (i.e. parse(), parse_file() and parse_fh()) are available. See that module's documentation for more information.

Note, as XML::SRS itself cannot be instantiated, you cannot call the to_xml() method from PRANG::Graph on it. However, each of the XML::SRS classes have this method available if you're interested in constucting XML documents. In particular, XML::SRS::Request can be used to construct an entire SRS request.

COMPOSED OF ^

PRANG::Graph, XML::SRS::Node

BACKGROUND ^

The SRS protocol was developed in 2002, using what were considered stable XML standard methods at the time, such as SGML DTD. This compares to the now de-facto standard, EPP (RFC3730, friends and updates), which was developed using XML Schema and XML Namespaces. As such, the SRS protocol as a stable standard far pre-dates EPP, which took a further 2 years to reach 1.0 status.

GLOBALS ^

There is currently a $XML::SRS::PROTOCOL_VERSION variable which includes the version of the SRS protocol parsed by the module. Currently, the ability to parse more than one version at a time is not supported, so in the event of registry protocol version changes, you will need to upgrade the version of XML::SRS in lock-step for any new functionality. This global is not exported.
