flash as3生成XML文件实现程序

var xmlstring:String="<a><b>wang</b><c>chun</c><d>lei</d></a>";
var myxml:XML=new XML(xmlstring);
trace(myxml.b);

var myxml:XML=new XML(<a><b>wang</b><c>chun</c><d>lei</d></a>);
trace(myxml.b);

var ids:Array = ["background", "photoArea", "thumbnail"];
var names:Array = [["0","0","1.jpg"], ["0","0","2.jpg"], ["0","0","3.jpg"]]//定义2个数组来给节点和属性赋值
var d:XML = new XML("<demo type='album'></demo>");//XML根节点
for (var i:int = 0; i < 3; i++)
{
    var newnode:XML = new XML();
    newnode =
        <component type={ids[i]}>//读取数组,属性赋值
            <property x={names[i][0]} y={names[i][1]}></property>//读取数组,属性赋值
            <info url={names[i][2]}></info>//读取数组,属性赋值
        </component>;

    d = d.appendChild(newnode)//注意这个方法来添加一个节点
}

trace(d)//这里输出构造完毕的XML

<demo type="album">
        <component type="background">
                <property x="0" y="0"/>
                <info url="res/bg.swf"/>
        </component>
      <component type="photoArea">
                <property x="320" y="280"/>
                <info url="res/pa.swf"/>
       </component>
       <component type="thumbnail">                
                 <property x="580" y="10"/>
                 <info url="res/th.swf"/>
        </component>
</demo>
