Read xml data using Xml.Linq to generic list

using Xml.Linq.XDocument is very easy. now lets see how to pick the following xml file into xdocument and query with in the filedata using XML.Linq

< ?xml version="1.0" encoding="utf-8" ? >
< Cities >
< City StationName="Mumbai" >
< WeatherCondition >Not Extreem< /WeatherCondition >
< WindDirection >North-to-South< /WindDirection >
< Temperature >30 degree C< /Temperature >
< DewPoint >16< /DewPoint >
< Humidity >14.05< /Humidity >
< WindSpeed >Mild< /WindSpeed >
< /City >
< City StationName="Kolkata" >
< WeatherCondition >Dry< /WeatherCondition >
< WindDirection >East-to-South< /WindDirection >
< Temperature >32 degree C< /Temperature >
< DewPoint >11< /DewPoint >
< Humidity >12.35< /Humidity >
< WindSpeed >Strong< /WindSpeed >
< /City >
< City StationName="Delhi" >
< WeatherCondition >Hot< /WeatherCondition >
< WindDirection >East-to-North< /WindDirection >
< Temperature >42 degree C< /Temperature >
< DewPoint >7< /DewPoint >
< Humidity >11.35< /Humidity >
< WindSpeed >Strong< /WindSpeed >
< /City >
< /Cities >

Now read the above xml data using Xml.Linq.XDocument

public static List GetAllCities()
{
// Load a Xml File into XDocument class
XDocument xmlDoc = XDocument.Load(@"App_Data/CitiesClimate.xml");

// Read the Xml data into a
var cities = from xmlData in xmlDoc.Elements("Cities").Elements("City")
select xmlData;

Climate climate = null;
List climateList = new List();

//Now loop through all the cities in resultset
foreach (var city in cities)
{
climate = new Climate();
climate.StationName = city.Attribute("StationName").Value;
climate.WeatherCondition = city.Element("WeatherCondition").Value;
climate.WindDirection = city.Element("WindDirection").Value;
climate.Temperature = city.Element("Temperature").Value;
climate.DewPoint = Convert.ToDecimal(city.Element("DewPoint").Value) ;
climate.Humidity =Convert.ToDecimal(city.Element("Humidity").Value);
climate.WindSpeed = city.Element("WindSpeed").Value;
climateList.Add(climate);
}

return climateList;
}



Now see how to search some records
// Here we can perform search
var cities1 = from xmlData in xmlDoc.Elements("Cities").Elements("City")
where Convert.ToInt32(xmlData.Elements("DewPoint")) > 11
select xmlData;
