NextSibling Skipping Whitespace

A simple helper to follow .nextSibling properties, but skip text nodes to return elements.

function nextSibling(start) {
  var nextSib;
  if (!(nextSib=start.nextSibling)) {
    return false;
  }
  while (nextSib.nodeType!=1) {
    if (!(nextSib=nextSib.nextSibling)) {
      return false;
    }
  }
  return nextSib;
}

Example Usage:

if (nextSib=nextSibling(element)) {
  alert(nextSib.innerHTML);
}
