Question

在暂时不使用它之后返回flex，尝试使用dataprovider将一些xml（由php生成）加载到数据网格中，以创建一个简单的网格，显示一周内的每日高温和低温。我可以获取数据显示在我的数据网格中，但列是按随机顺序加载的。（所以星期五在星期一之前到来等等）所以我只想弄清楚如何将特定数据分配给特定的数据域。

这是flex代码; （更新为工作代码。请注意，dataFields只包含xml标记的名称和/或这些标记内的标记名称）

<?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>

php生成的xml是这个; （根据评论编辑）

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

    </mon>
    <tues>

Answer 1

我给你的建议是迭代xml并将其转换为数据模型，以便更容易使用。像

这样的东西

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

这样您就可以将实际日期添加到列数据字段中。你不需要使用直接的xml，这对于使用anywho很烦人。只需要将它映射到一个对象。您可以使用Spicefactory's XML object mapper来完成工作。

尝试将xml分配到特定的datagrid数据字段中
