ActionScript 2.0 :: Passing Parameters With A Mouse Event On A Button

I would like to pass Parameters to a functions from a button click. Currently I need to call a function that in turn passes the Parameters.

example
gardengate_btn.addEventListener(MouseEvent.CLICK, onClick_gardengate);
function onClick_gardengate(e:MouseEvent):void{
/*Sends the xml and the paintingCount_Numb to the parseXML function.
This will display the text and images for each painting
*/
ParseXML(xmlData,0);
}

I would think that i could just do this but it gives me an error. gardengate_btn.addEventListener(MouseEvent.CLICK, ParseXML(xmlData,0)); 1067: Implicit coercion of a value of type void to an unrelated type Function.
