Both, but they're a bit different. The nodeValue field is defined for
all Nodes and maps to different things depending on the node type.
The data field is defined on Nodes that inherit from CharacterData,
which is to say Text, CDATASection, and Comment nodes. For those
three node types, nodeValue maps straight to data. I know it's weird,
but the DOM does have quite a few such irrelevant duplication due to
trying to make the vendors happy back then.
Note that if the implementation you're using supports DOM 3 or the
uDOM then you don't want to use fooElem.firstChild.data (which is
wrong and will blow up in a number of cases) but rather
fooElem.textContent which will do what you really want most of the time.
