traverse every element in xml tree using linq to xml

I would like to traverse every element and attribute in an xml and grab the name an value without knowing the names of the elements in advance. I even have a book on linq to xml with C# and it only tells me how to query to get the value of elements when I already know the name of the element.

The code below only gives me the most high level element information. I need to also reach all of the descending elements.

            XElement reportElements = null;
            reportElements = XElement.Load(filePathName.ToString());


            foreach (XElement xe in reportElements.Elements())
            {

                MessageBox.Show(xe.ToString());
            }
