title: Getting DOM node from React child element
body: <p>Using the <code>React.findDOMNode</code> method that was introduced in v0.13.0 I am able to get the DOM node of each child component that was passed into a parent by mapping over <code>this.props.children</code>.</p>
  
  <p>However, if some of the children happen to be React Elements rather than Components (e.g. one of the children is a <code>&lt;div&gt;</code> created via JSX) React throws an invariant violation error.</p>
  
  <p>Is there a way to get the correct DOM node of each child after mount regardless of what class the child is?</p>
