title: Anyone have a diff algorithm for rendered HTML?
body: <p>I'm interested in seeing a good diff algorithm, possibly in Javascript, for rendering a side-by-side diff of two HTML pages. The idea would be that the diff would show the differences of the <em>rendered</em> HTML.</p>
  
  <p>To clarify, I want to be able to see the side-by-side diffs <em>as</em> rendered output. So if I delete a paragraph, the side by side view would know to space things correctly.</p>

  <p>@Josh exactly. Though maybe it would show the deleted text in red or something. The idea is that if I use a WYSIWYG editor for my HTML content, I don't want to have to switch to HTML to do diffs. I want to do it with two WYSIWYG editors side by side maybe. Or at least display diffs side-by-side in an end-user friendly matter.</p>
