Xml Parsing in C# - c#-4.0

Question

http://earthquake.usgs.gov/earthquakes/feed/v1.0/summary/2.5_day.atom on this site, I wrote the following code to retrieve the data.
protected void Button1_Click(object sender, EventArgs e)
{
string adresal = "http://" + txtAd.Text;
WebResponse GelenCevap;
WebRequest adresistegi = HttpWebRequest.Create(adresal);
GelenCevap = adresistegi.GetResponse();
StreamReader CevapOku = new StreamReader(GelenCevap.GetResponseStream());
string KaynakKodlar = CevapOku.ReadToEnd();
XmlDocument xmlDoc = new XmlDocument(); // Create an XML document object
xmlDoc.Load("http://earthquake.usgs.gov/earthquakes/feed/v1.0/summary/2.5_day.atom"); // Load the XML document from the specified file
XmlNodeList depremler = xmlDoc.GetElementsByTagName("entry");
foreach (XmlNode node in depremler)
{
var a = node.ChildNodes;
foreach (XmlElement x in a)
{
ListBox1.Items.Add(x.InnerText);
}
}
}
In this way I get all the data in the ListBox.But I need to assign them to variable data line by line.How can I do? I would appreciate if you can help.
Also i need id,title, updated, georss:point,georss:elev variables.

Answer 1

First add an Enrty and Category class:
public class Entry
{
public string Id { get; set; }
public string Title { get; set; }
public string Updated { get; set; }
public string Summary { get; set; }
public string GPoint { get; set; }
public string GElev { get; set; }
public List<string> Categories { get; set; }
}
public class Category
{
public string Label { get; set; }
public string Term { get; set; }
}
Then use LINQ to XML
XDocument xDoc = XDocument.Load("path");
List<Entry> entries = (from x in xDoc.Descendants("entry")
select new Entry()
{
Id = (string) x.Element("id"),
Title = (string)x.Element("title"),
Updated = (string)x.Element("updated"),
Summary = (string)x.Element("summary"),
GPoint = (string)x.Element("georss:point"),
GElev = (string)x.Element("georss:elev"),
Categories = (from c in x.Elements("category")
select new Category
{
Label = (string)c.Attribute("label"),
Term = (string)c.Attribute("term")
}).ToList();
}).ToList();
