getElementsByTagName() equivalent for textNodes

Question

Is there any way to get the collection of all textNode objects within a document?

getElementsByTagName() works great for Elements, but

Answer 1

Here's an alternative that's a bit more idiomatic and (hopefully) easier to understand.

function getText(node) {
    // recurse into each child node
    if (node.hasChildNodes()) {
        node.childNodes.forEach(getText);
    }
    // get content of each non-empty text node
    else if (node.nodeType === Node.TEXT_NODE) {
        const text = node.textContent.trim();
        if (text) {
            console.log(text); // do something
        }
    }
}
