title: Check all the children for XElement
body: <p>I have <code>XElement</code> object which is my XML tree read from XML file. Now I want to check all the nodes in this tree to get first attribute name and value. Is there any simple way to go through all of the nodes (from root till leaves)? My XML file has got very many different and strange nodes - that's why it's harder to solve this issue. I thought about writing some recursion, but hope it's another way to solve that easier.</p>
