title: Insert a div element as parent
body: <p>I'm just wondering if the following is possible, lets say we have a dom element and we want to wrap this element in a div. So a div is inserted between the element and it's parent. Then the div becomes the element's new parent.</p>
  
  <p>But to complicate things, elsewhere we have already done things like: </p>
  
  <pre><code>var testElement = document.getElementByID('testID')
  </code></pre>
  
  <p>where testID is a child of the element to be warapped in a div. So after we have done our insertion will testElement still be valid?</p>
  
  <p>BTW: I'm not using jquery.</p>
  
  <p>Any ideas?</p>
  
  <p>Thanks,</p>
  
  <p>AJ</p>
