There's a table in http://www.w3.org/TR/DOM-Level-2-Core/core.html#ID-1950641247
which summarizes what you can expect from nodeValue depending on the
node type. You'll note that it is 'null' in many cases.
If 'n' above is not a Text node (or Comment node, CDATA node, etc.)
then 'text' will be 'null'. AFAICT, there's no shortcut in "core DOM"
to get the "text content" of an Element node, you have to walk the
subtree and accumulate the Text/CDATA nodes' nodeValue.
