試圖XML分配成特定的數據網格數據域

Question

再回到不使用一段時間後彎曲，嘗試使用數據提供器來創建表示每日高溫和低溫下一個簡單的網格將一些XML（由PHP生成）加載到數據網格在一個星期的過程中。我可以將數據顯示在我的數據網格中，但是列以隨機順序加載。 （所以週五是星期一前等來了），所以我只是想弄清楚如何具體數據分配給特定的數據域。

這裏的Flex代碼; （更新工作代碼。請注意，數據域只包含XML標記/的名稱或標記的這些標記內的名字）

<?xml version="1.0" encoding="utf-8"?> 

<fx:Declarations> 
    <s:HTTPService id="weather" url="http://localhost/weather/index.php" result="weather_resultHandler(event)" fault="weather_faultHandler(event)" /> 
</fx:Declarations> 


<fx:Script> 
    <![CDATA[ 
     import mx.collections.ArrayCollection; 
     import mx.controls.Alert; 
     import mx.rpc.events.FaultEvent; 
     import mx.rpc.events.ResultEvent; 

     //Setup array making sure to import Array Collection 
     [Bindable] 
     public var mydata:ArrayCollection = new ArrayCollection(); 

     protected function weather_resultHandler(event:ResultEvent):void 
     { 
      trace(event.result.weather.city); 
      //mydata is our array and we are adding the info to it. Show the xml file. 
      mydata = event.result.weather.city;    
     } 

     protected function weather_faultHandler(event:FaultEvent):void 
     { 
      //import Alert so we can use this class 
      Alert.show("There is a problem with the data connection"); 
     } 
    ]]> 
</fx:Script> 


<mx:DataGrid x="49" y="226" id="weatherGrid" dataProvider="{mydata}"> 
    <mx:columns> 
     <mx:DataGridColumn headerText="City" dataField="name"/> 
     <mx:DataGridColumn width="40" headerText="High" dataField="mon.high"/> 
     <mx:DataGridColumn width="40" headerText="Low" dataField="mon.low"/>     
     <mx:DataGridColumn width="40" headerText="High" dataField="tues.high"/> 
     <mx:DataGridColumn width="40" headerText="Low" dataField="tues.low"/> 
     <mx:DataGridColumn width="40" headerText="High" dataField="wed.high"/> 
     <mx:DataGridColumn width="40" headerText="Low" dataField="wed.low"/> 
     <mx:DataGridColumn width="40" headerText="High" dataField="thurs.high"/> 
     <mx:DataGridColumn width="40" headerText="Low" dataField="thurs.low"/> 
     <mx:DataGridColumn width="40" headerText="High" dataField="fri.high"/> 
     <mx:DataGridColumn width="40" headerText="Low" dataField="fri.low"/> 
     <mx:DataGridColumn width="40" headerText="High" dataField="sat.high"/> 
     <mx:DataGridColumn width="40" headerText="Low" dataField="sat.low"/> 
     <mx:DataGridColumn width="40" headerText="High" dataField="sun.high"/> 
     <mx:DataGridColumn width="40" headerText="Low" dataField="sun.low"/> 
    </mx:columns> 
</mx:DataGrid> 

而XML生成的XML是這個; （基於評論編輯）

<?xml version="1.0" encoding="utf-8" ?><weather><city> 
    <name>London</name> 
    <mon> 
     <high>-2</high> 
     <low>-10</low> 
    </mon> 
    <tues> 
     <high>-1</high> 

     <low>-5</low> 
    </tues> 
    <wed> 
     <high>0</high> 
     <low>-2</low> 
    </wed> 
    <thurs> 

     <high>3</high> 
     <low>0</low> 
    </thurs> 
    <fri> 
     <high>5</high> 
     <low>2</low> 
    </fri> 

    <sat> 
     <high>8</high> 
     <low>4</low> 
    </sat> 
    <sun> 
     <high>10</high> 
     <low>6</low> 

    </sun> 
</city><city> 
    <name>Toronto</name> 
    <mon> 
     <high>-5</high> 
     <low>-10</low> 
    </mon> 

    <tues> 
     <high>-8</high> 
     <low>-15</low> 
    </tues> 
    <wed> 
     <high>-2</high> 
     <low>-7</low> 

    </wed> 
    <thurs> 
     <high>3</high> 
     <low>-3</low> 
    </thurs> 
    <fri> 
     <high>6</high> 

     <low>0</low> 
    </fri> 
    <sat> 
     <high>7</high> 
     <low>3</low> 
    </sat> 
    <sun> 

     <high>9</high> 
     <low>4</low> 
    </sun> 
</city></weather> 

Answer 1

我對你的建議是迭代你的XML並將其轉換爲數據模型，以使其更易於使用。類似於

WeatherModel 
    monday 
     high 
     low 
    tuesday 
     high 
     low 
    wednesday 
     high 
     low 
    thursday 
     high 
     low 
    friday 
     high 
     low 
    saturday 
     high 
     low 
    sunday 
     high 
     low 

這樣，您可以將實際日添加到列數據字段。你不需要使用直接的XML，這是討厭任何人工作。只需要將其映射到一個對象。您可以使用Spicefactory's XML object mapper來完成這項工作。
