You probably have to give some more information...
What you could do, is something like this:
Dom.Document doc = new Dom.Document();
doc.load(yourstringwiththexml);
DOM.XMLNode root = doc.getRootElement();
for(Dom.XMLNode dataNode : root.getChildren()) {
loop trough the fields this needs some more code.
}
define some custom classes like:
public class WeatherData {
Location location;
Forcast forcast;
}
public class Location {
public String locationName;
public String locationType;
public String locationCountry;
public String locationTimezone;
}
public class Forecast {
list <ForcastTime> forcastTimes;
}
public class ForcastTime {
String symbolNumber;
etc.
}
When you loop trough the XML, you create the classes and populate them. Then you return the weatherData class to your visualForce page.
This is somewhat typed from the head so you'll have to dive into this yourself.
Hi
Thanks for the reply,i'm very new to this i'm unable to parse and display it on vf page
my requirement is
i have to display forecast details of a particular city which is entered by user in a input text box on the vf page could you please elaborate your answer.
If you're new to this than I advise you to read some documentation first on Visualforce and Apex.
Here is some documentation on XML parsing:
http://www.salesforce.com/us/developer/docs/apexcode/Content/apex_xml_dom.htm
This is not something basic so this may be a bit over your head if you're new to this.
