          <description> The method insertBefore inserts the node newChild before the existing child node refChild. If refChild is null, insert newChild at the end of the list of children. Using insertBefore on an Element node attempt to insert new Comment/PI and CDATA nodes before each other and verify the names of the newly inserted nodes. </description>
