How to get name of System.Xml.Linq.XNode?

Each XML element, like <title /> has a name - "title". I using foreach to parse XNode.Nodes() return and handle tags by their name.

I was sucessfuly using casting from XNode to XElement, to access XElement.Name.LocalName property, which was returning "title".

foreach(XElement as_element in doc.Nodes())

Problem appeared after i tried to parse this tag:

<title>"Some text"</title>

Now it has type XText (: XNode), and i cannot cast it to XElement. I get an InvalidCastException. How can i get XNode's "name"?
