Mono: linq to xml: how to select the value from elements
Today I manage to make linq queries in mono and want to share my experiences with you…
To use linq in mono, you need two basic libraries which are:
System.Core and System.Xml.Linq
My first usage is as follows:

using System;
using System.Linq;
using System.Xml.Linq;
public class MainClass {
public static void Main() {
XElement xmlDoc = XElement.Parse(
@"
<data>
<gpsdata lat='51.052887' lon='4.880805'>
<name>1</name>
<cgps id='0' track ='1'/>
</gpsdata>
<gpsdata lat='51.055329' lon='4.900954'>
<name>2</name>
<cgps id='1' track ='1'/>
<cgps id='2' track ='2'/>
<cgps id='3' track ='5'/>
</gpsdata>
</data>
");
var titles = (from gpsdata in xmlDoc.Elements("gpsdata").Elements("cgps")
where gpsdata.Attribute("id").Value == "3"
select gpsdata.Attribute("track"));
foreach (var title in titles){
Console.BackgroundColor=ConsoleColor.White;
Console.ForegroundColor=ConsoleColor.Black;
Console.WriteLine(title.ToString());
Console.ResetColor();
}
}
}
