XML Calendar

[alpharaven]

I created a basic events page that pulls all the info from an xml. What I need to know is how can I have flash go to the next event automatically once the date for the previous event has passed.
AS:

prev_btn._x = news_txt._x;
next_btn._x = news_txt._x+news_txt._width;
//
mon = ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Oct", "Nov", "Dec"];
weekdays = ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"];
now = new Date ();
nDay = weekdays[now.getDay ()];
nMonth = mon[now.getMonth ()];
nDate = now.getDate ();
//
function loadXML (loaded) {
    if (loaded) {
        xmlNode = this.firstChild;
        news = [];
        description = [];
        day = [];
        date = [];
        time = [];
        month = [];
        venue = [];
        total = xmlNode.childNodes.length;
        for (i=0; i<total; i++) {
            day* = xmlNode.childNodes*.childNodes[0].firstChild.nodeValue;
            month* = xmlNode.childNodes*.childNodes[1].firstChild.nodeValue;

            news* = xmlNode.childNodes*.childNodes[3].firstChild.nodeValue;
