Flex4中动态解析XML数据并转换为ArrayCollection

在Flex4中处理xml数据，为了方便，一般采用SimpleXMLDecoder直接转换为ArrayCollection

但有时为了处理xml中的数据，特别是xml文件中包含日期型数据（Date）时，就需要自己解析XML并进行相应的处理

						var _attValue:String = myXML.area[i].attribute(_attName);
					
						// 设置Object属性
						_item[_attName] = _attValue;
					}  
					
					// 添加到ArrayCollection中
					chartData.addItem(_item);
