Parsing XDocument using LINQ

Question

I am doing the following query on an XDocument. The last level .Descendants("Instance") yields a list of XElements of the form:

<Instance>filepath1</Instance>
<Instance>filepath2</Instance>
<Instance>filepath3</Instance>
<Instance>filepath4</Instance>

Query

 List<string> fileNames = xDoc.Descendants("Main")
                       .FirstOrDefault()
                       .Descendants("SecondLevel")
                       .FirstOrDefault()
                       .Descendants("Instance")
                       .Select().ToList(); //this line is not correct. Need to get the instances node values as List<string>

How can I store the values filepath1, filepath2.. in the List<string>?

Something like Select(x=>x.Value) ?

By using

 ....
  .Descendants("Instance")
  .Select(e => e.Value) // project to the string values
  .ToList();

Thanks, it worked. Forgive my ignorance, what is that syntax. It looks like writing anonymous functions with Lamda expressions.

It is a lambda expression. It Converts the found XElements into their string Values. Read up on basic LINQ, any tutorial will do.
