Code:
document.addEventListener('load', function() {
var treeWalker = document.createTreeWalker(document, NodeFilter.SHOW_TEXT, { acceptNode: function(node) { return /\S/.test(node.nodeValue) ? NodeFilter.FILTER_REJECT : NodeFilter.FILTER_ACCEPT } }, false);
while (treeWalker.nextNode())
treeWalker.currentNode.parentNode.removeChild(treeWalker.currentNode);
}, true);
Behold the awesomeness of DOM2 Traversal.
