public static function close_dangling_tags(str:String):String {
			var open_tags:Array = str.match(/<[a-z]+( .*)?(?!\/)>/img).map(function(e:*,i:int,arr:Array):String{return e.substr(1,e.length-2) });
			var closed_tags:Array = str.match(/<\/[a-z]+>/img).map(function(e:*,i:int,arr:Array):String{return e.substr(1,e.length-2) });
			if (open_tags.length == closed_tags.length){
				return str;
			}
			var tag_heap:Array = new Array();
			for each(var tag:String in open_tags) {
				tag_heap.push(tag);
				while (tag_heap.length && closed_tags.length && ArrayTools.last(tag_heap) == ArrayTools.first(closed_tags)) {
					tag_heap.pop();
					closed_tags.shift();
				}
			}
			return str+tag_heap.reverse().map(function(e:*,i:int,arr:Array):String{return '</'+e+'>'}).join('');
