org.w3c.dom.Element doesn't represent the start tag; it represents the 
entire element.  Anything occuring between the start and end tag will beomce 
children of that element.  E.g.

<start>This is <i>italicized</i>text.</start>

resluts in five Nodes:

1. An Element with the tag name "start"
2. A Text with the node value "This is "
3. An Element with tag name "i"
4. A Text with the node value "italicized"
5. A Text with the node value "text."

2, 3, and 5 are (in that order) the child node of 1.  4 is the child of 3.

And in DOM, there's no way to distinugish between, say,

    <start></start>

and

    <start/>

In both case, you see an Element wth no children.
