I have simple DOM

<b><i>node one</i><i><s>node two</s></i>node three</b>.

How do I remove all wrappers from only one element (for example: node two) so that other elements remain in their wrappers. The final DOM should become

<b><i>node one</i></b> node two <b>node three</b>

Jquery method unwrap() in loop destroy top b for all
