The `normalize` > method, where supported, will combine adjacent text nodes. 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.
