          <description> The "setAttribute(name,value)" method adds a new attribute to the Element. If the "name" is already present, then its value should be changed to the new one that is in the "value" parameter. Retrieve the last child of the fourth employee, then add an attribute to it by invoking the "setAttribute(name,value)" method. Since the name of the used attribute("street") is already present in this element, then its value should be changed to the new one of the "value" parameter. </description>
