在一个XML文件中选择特定的数据

我有这个xml文件

<data-set xmlns:xsi="www.w3/2001/XMLSchema-instance"> <record> <Date>1 July</Date> <Ville>New-York</Ville> <haute>6h50</haute> <basse>1h14</basse> <haute2>20h01</haute2> <basse2>13h16</basse2> </record> <record> <Date>2 July</Date> <Ville>New-York</Ville> <haute>7h36</haute> <basse>1h59</basse> <haute2>20h41</haute2> <basse2>13h56</basse2> </record> <record> <Date>3 July</Date> <Ville>Miami</Ville> <haute>8h21</haute> <basse>2h44</basse> <haute2>21h22</haute2> <basse2>14h37</basse2> </record> </data-set>

我想，在我的AS3 code，才能够从这个XML文件中选择特定的数据。

I would like, in my AS3 code, to be able to select specific data from this xml file.

例如：

var currentDate=new Date(); var day=currentDate.getDate(); If the day == one of the day of the xml, display "haute" of the corresponding day.

这可能吗？我该怎么办呢？

Is it possible ? How can I do that ?

推荐答案

您可以做你正在寻找通过过滤由属性或元素的XML数据，了解更多详情什么看一看此处。

You can do what you are looking by filtering your xml data by attribute or element, for more details take a look here.

因此​​，对于你的例子，你可以这样做：

So for you example, you can do like this :

var xml:XML = <data-set xmlns:xsi="www.w3/2001/XMLSchema-instance"> <record> <Date>1 July</Date> <Ville>New-York</Ville> <haute>6h50</haute> <basse>1h14</basse> <haute2>20h01</haute2> <basse2>13h16</basse2> </record> <record> <Date>2 July</Date> <Ville>New-York</Ville> <haute>7h36</haute> <basse>1h59</basse> <haute2>20h41</haute2> <basse2>13h56</basse2> </record> <record> <Date>3 July</Date> <Ville>Miami</Ville> <haute>8h21</haute> <basse>2h44</basse> <haute2>21h22</haute2> <basse2>14h37</basse2> </record> </data-set> ; var search:XMLList = xml.record.(Date == '3 July'); if(search){ trace(search.haute); // gives : 8h21 }

和从外部文件加载数据时：

And when loading data from an external file :

var loader:URLLoader = new URLLoader(); loader.addEventListener(Event.COMPLETE, on_xml_loaded); loader.load(new URLRequest('xml.xml')); function on_xml_loaded(e:Event){ var xml:XML = new XML(e.target.data); var search:XMLList = xml.record.(Date == '3 July'); if(search){ trace(search.haute); // gives : 8h21 } }

希望能有所帮助。

Hope that can help.
