You can make a reasonable version of innerText using a regular
expression and innerHTML:

  var re = /<[^<>]+>/g;
  var iText = theDiv.innerHTML.replace(re,'');

If you have form controls with text content (e.g. textarea or option
elements) it will be best to not have them inside the label or the
above will return their text too (I don't know what innerText does
with that).

DOM 3 has 'textContent', but I don't think it's particularly well
supported just yet - v. 1.0 became a recommendation in April 2004.
