First Load the Document:

var doc = XDocument.Load("c:somefile.xml");

Then you can access the Elements with

XElement xe = doc.Element("Name of the Element");

If you got more than one Element with the same name you can get them with:

IEnumerable<XElement> xe = doc.Elements("Name of the Element");

You can Access Attributes kind of similar:

XAttribute xa = doc.Attribute("Name of the Attribute");

and

IEnumerable<XAttribute> xa = doc.Attributes("name");

don't forget to always do null checks.

I hope this helps.
