來自Geocode Api的XML無法通過AS3轉換爲XML

Question

AS3代碼寫得很差，我需要從Google Maps Api檢索XML數據並從中檢索節點/字符串。沒有發生。我需要使用XML Data作爲變量值，然後將它的子節點和該子節點放入數組中（有點像我的推特XML數據）。這是我的輸出：

     function getTweets(e:Event):void

      if (e.target.data) 
      { 
       var tweets = new Array(); var times = new Array(); 
       var twitterXML:XML = new XML(e.target.data);

        trace(tweets[tweets.length - 1][1]);

      geoLoader.load(geoReq); 
     } 
     function locate(e:Event):void 
     { 
      geoXml = e.target.data; 
      //geoLocList = geoXml.children(); 
      //geoLoc = [geoLocList[0].*::lat, geoLocList[0].*::lng]; 
      trace("located"); 
      trace(e.target.data); 
      //trace(geoXml); 
      trace("located"); 
     } 
    } 
} 

請幫幫忙，先謝謝了，凱爾。

Answer 1

您得到的結果是String，所以您需要基於String創建一個新的XML對象。

在你locate()方法改變這一行：

geoXml = e.target.data; 

要：

geoXml = new XML(e.target.data);
