Removing items from List Component

Question

Below is a function set that's used to get info from an XML
source(s) and populate a List Component (videoList). Works great.
The second function loads data from a separate XML source and
populates the SAME List Component. When the second function is
called it loads the data in addition to the existing data into the
List Component. I want it to REPLACE the data. How would I
accomplish this?
public function getXMLdata(event:Event):void {
var campXML:XML = new XML(xmlLoader.data);
var vid:XML;
for each(vid in campXML.vid) {
videoList.addItem({label:vid.attribute("desc").toXMLString(),
data:vid.attribute("src").toXMLString(),
text:vid.attribute("text").toXMLString()});;
videoList.selectedIndex = 0;
videoList.addEventListener(Event.CHANGE, playnewvid);
FLVPlayer.source = videoList.selectedItem.data;
FLVPlayer.pause();
clipText.text = videoList.selectedItem.text;
public function getXMLdata2(event:Event):void {
var nflXML:XML = new XML(xmlLoader2.data);
var vid:XML;
for each(vid in nflXML.vid) {
videoList.addItem({label:vid.attribute("desc").toXMLString(),
data:vid.attribute("src").toXMLString(),
text:vid.attribute("text").toXMLString()});;
videoList.selectedIndex = 0;
videoList.addEventListener(Event.CHANGE, playnewvid);
FLVPlayer.source = videoList.selectedItem.data;
FLVPlayer.pause();
clipText.text = videoList.selectedItem.text;
}

That took 2 minutes! Works like a charm Manno. Thank you for
your response.
For those curious, here's the solution:
public function getXMLdata(event:MouseEvent):void {
videoList.removeAll();
var campXML:XML = new XML(xmlLoader.data);
var vid:XML;
for each(vid in campXML.vid) {
videoList.addItem({label:vid.attribute("desc").toXMLString(),
data:vid.attribute("src").toXMLString(),
text:vid.attribute("text").toXMLString()});;
videoList.selectedIndex = 0;
videoList.addEventListener(Event.CHANGE, playnewvid);
FLVPlayer.source = videoList.selectedItem.data;
FLVPlayer.pause();
clipText.text = videoList.selectedItem.text;
public function getXMLdata2(event:MouseEvent):void {
videoList.removeAll();
var nflXML:XML = new XML(xmlLoader2.data);
var vid:XML;
for each(vid in nflXML.vid) {
videoList.addItem({label:vid.attribute("desc").toXMLString(),
data:vid.attribute("src").toXMLString(),
text:vid.attribute("text").toXMLString()});;
videoList.selectedIndex = 0;
videoList.addEventListener(Event.CHANGE, playnewvid);
FLVPlayer.source = videoList.selectedItem.data;
FLVPlayer.pause();
clipText.text = videoList.selectedItem.text;
}
