Using loader in flash cs4 As2

1

Hello again
I am currently loading another swf file using the code below to my empty movie
but I want to do the same process using a loader, can anyone help?

var dewsliderpath = _root._url.substring(0, _root._url.lastIndexOf("/")) + “/dewslider_ori.swf?xml=” + xml;
DewSlider.loadMovie(dewsliderpath);
