NAME

WWW::IRail::API::Stations - HTTP::Request builder and HTTP::Response parser for the IRail API Station data

SYNOPSIS

    use WWW::IRail::API::Stations;
    use LWP::UserAgent();

    my $ua = new LWP::UserAgent();
       $ua->timeout(20);
             
    my $station_req = WWW::IRail::API::Stations::make_request();
    my $http_resp = $ua->request($station_req);
    my $result = WWW::IRail::API::Stations::parse_response($http_resp,'perl');

DESCRIPTION

This module builds a HTTP::Request and has a parser for the HTTP::Response. It's up to you to transmit it over the wire. If don't want to do that yourself, don't use this module directly and use WWW::IRail::API instead.

METHODS

make_request()

Has no arguments, requests the whole list of stations from the API

parse_response( {$http_response}, "dataType", filter() )

parses the HTTP::Response you got back from the server, which if all went well contains XML. That XML is then transformed into other data formats.

Note that the perl data format returns the data unnested for easier access.

  • xml

  • XML

  • YAML

  • JSON

  • perl (default)

example of output when dataType = 'xml'

    <stations>
      <station>\'S GRAVENBRAKEL</station>
      <station>AALST</station>
      <station>AALST KERREBROEK</station>
    
      <!-- ... snip ... -->

    </stations>
