E4Xを使用してXMLドキュメントを掘り下げたい結果を得るのに問題があります。たとえば、以下のXMLを使用して、 d_type SWを持つすべてのd_locationsを検索し、コードとhfloor番号（ d_typeより上のレベル）を含むすべてのSWd_typesのリストを作成します。 。

したがって、例を説明するために、次のようなリストを出力します。

タイプ：SW

18階：SW18.10N

15階：SW15.W2

15階：LB12

15階：LB17

S2階：SWS2.3

E4Xを使用してそれを行うにはどうすればよいですか？本当にありがとう！

あなたは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。これにより、XMLListが返されます。次に、その要素ごとに、必要な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">

;

次に、2段階のプロセスを実行するこの関数を作成します。

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 );        
    }
}

それを次のように呼びます

find("SW");
