Am I missing something here?  I always get a number several higher than what the document presents for child-elements of the root node.

There are empty text node children of the root as well:

<truck>
 |
 |--text node
 |
 |--<boat>
 |   |
 |   |--text node
 |
 |--text node
 |
 |--<state>
 |   |
 |   |--text node
 |
 |--text node

You can set parser options so that empty text nodes are stripped when
building the dom tree.
