I think you are being confused by the toString() implementation on an
Element. 'currentNode' isn't null -- if it were the line would be 'currentNode:
null'. It's a valid element. I don't have the source handy, but I beleive the
null is the 'value' of the node (Element nodes usually, if not always, have
null as a value in my experience).

Subject: Nodelist question
I am somewhat confused by the following snippet:
,----
| 1 Node currentNode;
| 2 Document doc = createDocument();
| 3 NodeList elementList = doc.getElementsByTagName( "element" );
| 4
| 5 if ( elementList.getLength() > 0 )
| 6 {
| 7 System.out.println( "elementList.getLength():" +
elementList.getLength() );
| 8 currentNode = elementList.item( 0 );
| 9 currentNodeIndex = 0;
| 10
| 11 NodeList elemChildren = currentNode.getChildNodes();
| 12 System.out.println( "elemChildren:length:" + elemChildren.getLength() ,
| 13 }
| 14 System.out.println( "currentNode:" + currentNode );
`----
The output is as follows:
,----
| elementList.getLength():5
| elemChildren:length:10
| currentNode:[element: null]
`----
Why is currentNode null? It's nodeType says ELEMENT_NODE. Am I
missing something fundamental here? The number of children do match up
with my document, BTW. I probably should change the name 'element', though,
to avoid confusion.
