Confusion about movieclip.target

I’m going thru the kirupa example of using loading XML data in flash. I came across this example, most of the logic makes sense to me but I don’t understand the syntax

preloadbar_mc.target = my_xml; //my_xml is reference to the loaded XML object.

what does movieclip.target mean? I’ve search for movieclip.target but could not find any documentation… your explanation is appreciated!


preloadbar_mc.onEnterFrame = function(){if (!this.target) return (0);var loaded = target.getBytesLoaded();var total = target.getBytesTotal();     var scale = 0;if (loaded && total){var percent = loaded/total;scale = 100 * percent;} this._xscale = scale;} preloadbar_mc.target = my_xml;
