Super quick Linq to XML

I was trying to figure out how to get started with Linq to XML, and found this article. I figured I'd simplify it even more for myself :)
Imagine we have the following file, saved in c:\contacts.xml

Then we can access it as follows
Notice:

  • on an XDocument, we can call descendants and pass it an element name, to get all the elements with that name (we can also call the no-args version, and get all descendants)
  • What we're getting is an XElement, on which we can call methods like Element or Attribute
  • We can directly cast an element into a string, and it gets us all the text inside that element
  • We can cast an attribute as a string, or an int (or even a float, double or many other types)
