A more general approach is simply to use the `nodeValue`
property, though both are acceptable.

The DOM 4 specification states[0] that textual content replacement
(`Node::textContent`, setting) is to be done by clearing
the `childNodes` of a node and appending a text node containing
the new text for Element and DocumentFragment nodes, while simply
replacing the `data` (and by proxy the `nodeValue`) for Text,
ProcessingInstruction and Comment nodes. I've written a fork
of `textContent` (to be released soon) that does precisely this.
Since Element nodes are the most desired context, the former
behavior is advised.
