adding class automation

i need to add class to dynamically created span tags so that i can highlight it for some duration of time and then i need to remove it from this span and add class to other span tag.. In short u can say add class and remove class should continues based on time on each of the span tags..

example:

Expand|Select|Wrap|Line Numbers

some text1some text2some text3

like this and i want text1 to be highlighted first and after few seconds second one should highlighted and so on..

Thanks in Advance

a simple start would be like this:

Expand|Select|Wrap|Line Numbers

 <html>

    <style type="text/css">

        .hl {

            color: red;

        }

    </style>

    <script type="text/javascript">

        function highlightNodes() {

            var nodeBase = document.getElementsByTagName('SPAN');

            var curNode = -1;
 
            for (var i = 0, n; n = nodeBase[i]; i++) {

                if (n.className == 'hl') {

                    curNode = i;

                    n.className = '';
 
                    if (curNode == nodeBase.length - 1) {

                        curNode = -1;

                    }

                }

            }
 
            nodeBase[curNode + 1].className = 'hl';

        }

    </script>

    <body onload="window.setInterval(highlightNodes, 1000);">

        <span>some text1</span>

        <span>some text2</span>

        <span>some text3</span>

    </body>

</html>

check it and try to understand it and adapt it to what u need. then come back with more specific questions.
