Understanding X-Path Expression
===

I'm trying to get an understanding of xpath in order to parse a [diffxml][1] file. I skimmed over the w3schools site. Am I understanding these correctly?

Statement 1: "/node()[1]/node()[3]"
<br>Selects the third child of the root node

Statement 2: "/node()[1]/node()[1]/node()[1]"
<br>Selects the child of the first node of the root node

Statement 3: "/node()[1]/node()[3]/node()[2]"
<br>Selects the second child of the third node under the root node.
