E4Xを使用して、親属性の子属性のリストを作成するにはどうすればよいですか？

Question

E4Xを使用して自分のXML文書を掘り下げたいという結果を得ることができません。私は、以下のXMLを使用して、やりたいexampleWhatについて、d_type SWを持ってd_locationsのすべてを見つけ、その後、コードとhfloor番号が含まれ、すべてのSWのd_typesのリストを作成している - これはd_typeより上のレベルです。

だから一例を説明するために、私は出力には、このようなリストが欲しい：

TYPE：SW

階18：SW18.10N

階15：SW15。 W2

フロア15：LB12

階15：LB17

フロアS2：SWS2.3

私はE4Xを使用していることをどのように行うことができますか？本当にありがとう！

Answer 1

次の2つのプロセスでそれを行う必要があります。最初にd_locationノードを収集します。これはXMLListを返します。次に、それの各要素について、あなたが望むフロアコードを含むh_floorノードである親を見つけます。

var xml:XML = <bldg><hfloor number="18"> 
    <d_location d_code="SW18.10N" d_type="SW" description="Ferbludgit thingamabob"> 
     <d_image>3e_pic1</d_image> 
     <d_image>3e_pic2</d_image> 
     <d_image>3e_pic3</d_image> 
     <d_image>3e_pic4</d_image> 
     <d_image>3e_pic5</d_image> 
     <d_video>3e_vid_1</d_video> 
     <d_video>3e_vid_2</d_video> 
     <d_video></d_video> 
    </d_location> 
</hfloor> 

<hfloor number="15">

;

その後、あなたは2段階のプロセスを行います。この関数を作成：

function find(type:String) { 
    var D_LOCATIONS:XMLList = (xml..d_location.(@d_type==type)); 
    for each (var loc:XML in D_LOCATIONS) { 
     trace("Floor:", loc.parent().@number, loc.@d_code);   
    } 
} 

は

find("SW");
