[flexcoders] Change the source of XML formatted data

[portuguesedanny]

Hi All,

The following app displays and filters the data correctly, but I want
to change the hardcoded XML data source to a HTTPservice source.
I have a url that generates dynamic XML data, I just dont know how to
change the hardcoded source to point to the dynamic source... Can
anyone Help!

I dont know how to change the following static data source:

################ SNIP Static Data Source ################
private function initData():void{
            dataList= new ArrayCollection([
            {name:"school A", city:"Paris"},
            {name:"school B", city:"Pomona "},
            {name:"School C", city:"Phillipsburg"},
            {name:"School D", city:"Liverpool"},
            {name:"School E", city:"Madrid"},
           ])
           }
############### /SNIP Static Data Source ################

and modify it so that it gets data from the following dynamic source:

################## Dynamic Data Source ##################
<mx:HTTPService id="getStaffList"
url="http://192.168.0.84/amfphp/stafflist.php"; />
################# /Dynamic Data Source ##################



NB:
The above HTTPservice stafflist.php script generates the following
data format:
