好友信息管理[flex]

一个通过本地存储过程实现的，使用xml加flex组件生成：

cookie类存储：

LocalShare.as
package ActionScript
{
   import flash.net.SharedObject;
   public class LocalShare
   {
       private var so:SharedObject;

       public function LocalShare(file_name:String = "FlashCookie"):void {
           so = SharedObject.getLocal(file_name);
       }

       public function flushDate(obj:*):void {
           so.data.saveInfo = obj;
           so.flush();
       }
       public function getData():* {
           //trace(so.data.saveInfo); //undefined
           return so.data.saveInfo;
       }
       public function clear():void {
            so.clear();
        }
   }
}

删除XML中指定索引号的节点：

code
package ActionScript
{
 public class Tool
 {
 /**
 * 删除xmlNode下指定索引处的节点
 */
 public static function deleteByIndex(xmlNode:XML,index:Number):XML{
 var newStr:String='';
 newStr+='<'+xmlNode.localName();
 for each (var att:XML in xmlNode.attributes()){
 newStr+=' '+att.localName()+'="'+att.toString()+'"';
 }
 newStr+='>';
 var i:Number=0;
 for each(var node:XML in xmlNode.children()){
 if(i!=index)
 newStr+=node.toXMLString();
 i++;
 }
 newStr+='</'+xmlNode.localName()+'/>';
 return new XML(newStr);
 }
 }
}
