function getText(node) {
 
if (node.nodeType === 3) {
return node.data;
}
 
var txt = '';
 
if (node = node.firstChild) do {
txt += getText(node);
} while (node = node.nextSibling);
 
return txt;
 
}

What is the difference between this and document.body.textContent ? Only browser support or there are other advantages ?
