Using AS3 to load XML data it's quite different than using AS2. In this tutorial I will explain to you, how we can load an external XML data, bring it to the fla file, and parse it to a List component. Using your notepad or similar program, make a simple XML file like the above example. <?xml version=”1.0″ encoding=”iso-8859-1″?> <news> Save it at the same directory as your fla file, naming it as news.xml . Now, the first step to load the xml file, we use the following code:
xmlLoader.load(new URLRequest(”news.xml”)); As you are using AS3, every time we define a variable, we must identify, which kind of variable is it. In the above code we say that the variable xmlLoader belongs to the URLLoader class ( xmlLoader:URLLoader ) , and the xmlData is the type XML ( xmlData:XML ). When the data is loaded, we must say to the code “where to go”. It's an event, so xmlLoader.addEventListener(Event.COMPLETE, LoadXML); , it's the same as saying that when the xml data was completely loaded, then calls the function LoadXML. Now drag a List component into stage, and name it as my_lst . The following code will define which data we want to show on the List component, as also parse into it. function LoadXML(e:Event):void { xmlData = new XML(e.target.data); ParseNews(xmlData); } function ParseNews(newsXML:XML):void { var newsList:XMLList = newsXML.item.title; f or each (var newsTitle:XML in newsList) { my_lst.addItem({label:newsTitle, data:newsTitle}); } } Run your movie. |
