                var oP1 = document.getElementById("p1");
                var oHello = oP1.firstChild.firstChild;
                var oWorld = oP1.lastChild;
                var oRange = document.createRange();
                
                oRange.setStart(oHello, 2);
                oRange.setEnd(oWorld, 3);
                oRange.deleteContents();
