FLEX_Array与XML

1.ArrayCollection转成xml类型示例
    下面模拟一组数据exams,将其转化为xml形式.详细代码见下：
     
     
         
         
                         import mx.collections.ArrayCollection;      
             [Bindable]private var shijxml:XML;
             
              private function init():void{
               shijxml = arrToXml(exams);
             }
            
           [Bindable]
           public var exams:ArrayCollection = new ArrayCollection(
                   [{sjtitle:"数据结构第一章", kemu:"数据结构",shijID:"sj000" ,num:"30"},  
                    {sjtitle:"数据结构第二章", kemu:"数据结构",shijID:"sj001" ,num:"30"},  
                   {sjtitle:"组成原理第一章", kemu:"组成原理",shijID:"zc000" ,num:"50"},                     
                   {sjtitle:"组成原理第二章", kemu:"组成原理",shijID:"zc001" ,num:"30"} ]);
                     
            private function arrToXml(arr:ArrayCollection):XML{
                   var root:XML = new XML("");
                   for(var i:int = 0;i                       var node:XML = new XML("");
                       node.sjtitle = arr[i].sjtitle;
                       node.kemu= arr[i].kemu;
                       node.shijID= arr[i].shijID;
                       node.num= arr[i].num;
                       root.appendChild(node);
                   }
                   return root;
               }
               private function closeHandler(event:Event):void {
                  show.text="试卷标题： "+ ComboBox(event.target).selectedItem;
                  var  temp:String=String(ComboBox(event.target).selectedItem);
                  for each(var xml:XML in shijxml.node){
                  if(xml.sjtitle==temp){
                       show.text="考试科目： "+xml.kemu+"\n"+"试卷题数： "+xml.num+"\n"+
                       "试卷编号： "+xml.shijID;
                   }
                 }    
               }      
           ]]>  
        
        
            
            
            
            
        
    



    
    
                 import mx.collections.ArrayCollection;        
         [Bindable]private var shijxml:XML;
        
          private function init():void{

        public var exams:ArrayCollection = new ArrayCollection(
