问题描述
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.
