Weather forecasting using X++

In todays competitive business world, there are many factors which determine the profit or loss.

Climatic conditions has its own impact and is becoming increasingly important for the corporates.
Like Demand forecast, weather forecast can be very helpful in business planning.
This Job is an attempt to predict the weather conditions in advance and organize things in such a way which will help the companies not
only to optimize their resources but also maximize their profits.
In the example, I used Yahoo released rss weather feeds: http://weather.yahoo.com/rss and XML programming to get the climatic conditionsThe format of the URL for the feed is:
http://xml.weather.yahoo.com/forecastrss?p=USNY0996&u=f
p is a US zip or a Yahoo! Weather location ID
u is the temp. units. ‘F’ for Fahrenheit (default) and ‘C’ for celciusstatic void weatherForecast(Args _args)
{
XmlDocument doc = new
XmlDocument();

XmlNamespaceManager ns;
XmlNodeList nodes;
XmlNode node;
//AddressZipCode addresszipCode;
container day(str _day)
{
;
switch(_day)
{
case ‘Mon’ : return [1,'Monday'];
case ‘Tue’ : return [2,'Tuesday'];
case ‘Wed’ : return [3,'Wednesday'];
case ‘Thu’ : return [4,'Thursday'];
case ‘Fri’ : return [5,'Friday'];
case ‘Sat’ : return [6,'Saturday'];
case ‘Sun’ : return [7,'Sunday'];
Default : return connull();
}
}
;
//addresszipCode = _args.record();
doc.Load("http://xml.weather.yahoo.com/forecastrss?p=
UKXX0085&u=c"
);// +
addresszipCode.ZipCode +’&u=c’);

// Set
up namespace manager for XPath

ns =
new XmlNamespaceManager(doc.nameTable());

ns.AddNamespace("yweather", "http://xml.weather.yahoo.com/ns/rss/1.0");
// Get
forecast with XPath

nodes
= doc.SelectNodes("//rss/channel/item/yweather:forecast", ns);

node =
nodes.nextNode();

setprefix("Weather forecast");
while
(node)

{
info("—————————————————–");
info(conpeek(day(node.attributes().getNamedItem("day").InnerText()),2));
info("—————————————————–");
info( node.attributes().getNamedItem("text").InnerText());
info(‘Min :’ +
node.attributes().getNamedItem("low").InnerText());

info(‘Max :’ +
node.attributes().getNamedItem("high").InnerText());

if(dayofwk(today()) ==
conpeek(day(node.attributes().getNamedItem("day").InnerText()),1))

{
info(‘Current :’ +
node.attributes().getNamedItem("code").InnerText());

}
else
{
info(‘Current : NA’);
}
node = nodes.nextNode();
}
}
Note: 1) An essential pre-requisite for the code to work is the URL should not be blocked by the firewall.2)We can directly use this job as an menuitemaction button by adding the job in menuitems under actions, Then add the button in the AddressZipcode form , for that make use of the commented code of AddressZipcode in the above Job.Here are some example location IDs (do not include the city name) or use the existing Zipcodes of AX
  • Beijing: CHXX0008
  • Helsinki: FIXX0002
  • London: UKXX0085
  • Moscow: RSXX0063
  • Munich: GMXX0087
  • Paris: FRXX0076
  • Riyadh: SAXX0017
  • Tokyo: JAXX0085
