Retrieving an Attribute Value from an XNode

Question

I have my XML file loaded and then I select my last element. Here is the code:

  XDocument doc = XDocument.Load("something.xml");
  var last = doc.Root.LastNode;

The code above outputs the last element on the XML file. Here is the code:

  <link num="4" url="yahoo.com">Yahoo</link>

I want to be able to select the value 4 of num. Here is the code:

  num="4"

How can I select the number 4 from my last node?

Try this:

XDocument xDoc = XDocument.Parse(xml);
string num = xDoc.Root.Elements().Last().Attribute("num").Value;
Console.WriteLine(num);
