here is a quick example:

this is DOES NOT INCLUDE ANYTHING involving a test field NOR scrolling the content.. purely the XML and extracting the data (dates) you need.

PHP Code:
//project vars/data
var month:Array = new Array("January""February""March""April""May""June""July""August""September""October""November""December");
var 
day:Array = new Array("Monday""Tuesday""Wednesday""Thursday""Friday""Saturday""Sunday");
var 
totalDates:Number;
var 
displayTotal:Number 3;


//create new date object
var todaysDate:Date = new Date();
trace("Day: "+day[todaysDate.getDay()]); 
trace("Date: "+todaysDate.getDate()); 
trace("Month: "+month[todaysDate.getMonth()]); 
trace("Year: "+todaysDate.getFullYear()); 

//create date string to compare against
var date_str:String = (todaysDate.getMonth()+1)+"/"+(todaysDate.getDate()+"/"+todaysDate.getFullYear());
trace("Todays Date: "+date_str);

var 
myXML:XML = new XML();
myXML.ignoreWhite true;
myXML.onLoad = function(success){
    if(!
success){
        
trace("XML data not found");
    }else{
        
trace("XML data found");
        
//trace("XML: "+myXML);
        
totalDates myXML.firstChild.childNodes.length;
        
trace("Total Dates: "+totalDates);
        
grabDates();
    }
}

myXML.load("dates.xml");


function 
grabDates(){
    for(
i=0i<totalDatesi++){
        var 
targetDate myXML.firstChild.childNodes[i].attributes.date;
        
trace("DATE: "+myXML.firstChild.childNodes[i].attributes.date);
        if(
date_str == targetDate){
            
trace("FOUND MY DATE");
            
trace("Node Index: "+i);
            for(
d=id<displayTotald++){
                
trace("Date: "+myXML.firstChild.childNodes[d].attributes.date);
                
trace("---------------------");
                
trace("Tour Name: "+myXML.firstChild.childNodes[d].childNodes[0].firstChild.nodeValue);
                
trace("Tour Location: "+myXML.firstChild.childNodes[d].childNodes[1].firstChild.nodeValue);
                
trace("Tour Time: "+myXML.firstChild.childNodes[d].childNodes[2].firstChild.nodeValue+newline);
            }
            break;
        }
    }

if you keep the DATE in the XML file the proper format m/d/yyyy

or mm/dd/yyyy if the months/days are double digits

take care..
