    In newer browsers you can use textContent for this.

    alert(document.getElementById('divText').textContent);

    In older browsers you need to walk through the DOM with .childNodes and test, if a node has nodeType === 3 (then it’s a text node) or nodeType === 1 (it’s an element you need to traverse recursively, too).

    You will also need this last solution, when you need to filter whitespace-only nodes, like the line breaks between tags.
