xml - 外部 XML 和 AS3

Question

我想向外部 XML 传递一个变量。我该怎么做呢？

我在做什么
- 用 COUNT XML 更新我的变量

我没有得到什么
- 整数到字符串值
- 如何将 XML 传递给变量

时间.xml

<?xml version="1.0" encoding="utf-8"?>
<SESSION>
    <COUNT TITLE="starting position">-77777</COUNT>
</SESSION>

xml.fla

//VARIABLES
/*CHANGE TO COUNT
MyString or count, I don't know if it was necessary to go from int to String 
*/
var myString:String = "";       
var count:int = int(myString);
    trace(count);

//LOAD XML
var myXML:XML;
var myLoader:URLLoader = new URLLoader();
myLoader.load(new URLRequest("time.xml"));
myLoader.addEventListener(Event.COMPLETE, processXML);

//PARSE XML
function processXML(e:Event):void {
    myXML = new XML(e.target.data);
    trace(myXML.COUNT.*);
    trace(myXML);

//TEXT 
var text:TextField = new TextField(); 
    text.text = myXML.COUNT.*; 
    addChild(text);
}

output window '正确追踪到输出窗口'

//zero should read -77777 if tracing correctly
0
-77777
<SESSION>
  <COUNT TITLE="starting position">-77777</COUNT>
</SESSION>

你问的有点模糊，但这里是如何从 XML 中提取数据作为字符串或整数：

//VARIABLES
var myString:String = "";       
var count:int = 0;

//LOAD XML
var myXML:XML;
var myLoader:URLLoader = new URLLoader();
myLoader.load(new URLRequest("time.xml"));
myLoader.addEventListener(Event.COMPLETE, processXML);

//PARSE XML
function processXML(e:Event):void {
    myXML = new XML(e.target.data);
    trace(myXML.COUNT.text()); //-77777

    //grab the data as a string
    myString = myXML.COUNT.text();

    //grab the data as an int
    count = int(myXML.COUNT.text());

    trace("String: ", myString);
    trace("Int: ", count);
    trace(count - 1); //just to show you that it's a number that you can do math with (-77778)

    //TEXT 
    var text:TextField = new TextField(); 
    text.text = myString; 
    addChild(text);
}
