          <description> If the "newChild" is a DocumentFragment object then all its children are inserted in the same order before the the "refChild". Create a DocumentFragment object and populate it with two Element nodes. Retrieve the second employee and insert the newly created DocumentFragment before its fourth child. The second employee should now have two extra children("newChild1" and "newChild2") at positions fourth and fifth respectively. </description>
