dict [obj]在35-36 xml節點處拉錯信息爲什麼？

Question

我不知道如何解釋這一點，但爲什麼不是這個代碼拉正確的圖像和圖標文件？它繼續在第35行提取錯誤的信息，這使得所有其他數據落後於一個節點。即使我刪除下面的三個位置，它仍然會導致xml錯誤。爲什麼會這樣做？

我驗證了xml數據並確保所有文件都在正確的文件夾中。

例如，這是從跟蹤結果：

pm#: 35 xmlnodename: Causey's Pharmacy iconFL: http://www.mysite.com/folder1/folder2/media/marker.png imgFL: http://www.mysite.com/folder1/folder2/media/century21_img.swf 
pm#: 36 xmlnodename: Century 21 Property Shoppe iconFL: http://www.mysite.com/folder1/folder2/media/century21_icon.gif imgFL: http://www.mysite.com/folder1/folder2/media/century21_img.swf 
pm#: 37 xmlnodename: Century 21 Property Shoppe iconFL: http://www.mysite.com/folder1/folder2/media/century21_icon.gif imgFL: http://www.mysite.com/folder1/folder2/media/type1.swf 

這是我在XML行34-36

<location> 
    <name>Bobby&apos;s Pharmacy</name> 
    <street>123 Steet St.</street> 
    <city>SomeCity</city>

    <motion>no</motion> 
    <featured>yes</featured> 
    <category>none</category> 
    </location> 

這裏是我的Flex代碼：

private var mediaLoc:String = "http://www.mysite.com/folder1/folder2/media/"; 

    public function addMarkers():void 
    { 
     var dict:Object = new Object(); 
     var i:Number = 0; 
     var e:Number = locXML..location.length()+1; 
     trace("add markers: " + locXML..location.length()); 
     for(i;i<e;i++){ 

     if (locXML.location.name[i.toString()]== "mapLogo"){ 
      trace(i + " logo"); 
      //get lat and long from xml 
      dict["locPointMarker_lat" + i.toString()] = locXML.location.lat[i.toString()]; 
      dict["locPointMarker_long" + i.toString()] = locXML.location.long[i.toString()]; 
      //get iconfile name from xml and append it to mediaLoc--filepath 
      dict["iconFileLink" + i.toString()] = mediaLoc + locXML.location.iconFile[i.toString()]; 
      //create a new url request using the dict["iconFileLink" + i.toString()] filepath 
      dict["iconFileReq" + i.toString()] = new URLRequest(dict["iconFileLink"+i.toString()]); 
      //create a new pointmarker for the map 
      dict["locPointMarker"+i.toString()] = new PointMarker(); 
      //apply buttonmode and handcursor to the new pointmarker 
      dict["locPointMarker"+i.toString()].buttonMode = dict["locPointMarker"+i.toString()].useHandCursor = true; 
      //create a loader to load the icon file 
      dict["icon"+i.toString()] = new Loader(); 
      //load the icon file 
      dict["icon"+i.toString()].load(dict["iconFileReq"+i.toString()], context); 
      //put the marker on the map 
      _map.putMarker(new Location(locXML.location.lat[i.toString()], locXML.location.long[i.toString()]), dict["locPointMarker"+i.toString()]); 
      trace("pm#: " + i + " xmlnodename: " + locXML.location.name[i.toString()] + " iconFL: " + dict["iconFileLink" + i.toString()] + " imgFL: " + dict["imageFileLink" + i.toString()]); 
      dict["locPointMarker"+i.toString()].mouseChildren=false;    
     }else{ 
      //the following else does the same thing except it also adds the image file 
      dict["locPointMarker_lat" + i.toString()] = locXML.location.lat[i.toString()]; 
      dict["locPointMarker_long" + i.toString()] = locXML.location.long[i.toString()]; 
      dict["iconFileLink" + i.toString()] = mediaLoc + locXML.location.iconFile[i.toString()]; 
      dict["iconFileReq" + i.toString()] = new URLRequest(dict["iconFileLink"+i.toString()]); 
      dict["locPointMarker"+i.toString()] = new PointMarker(); 
      dict["locPointMarker"+i.toString()].buttonMode = dict["locPointMarker"+i.toString()].useHandCursor = true; 
      dict["icon"+i.toString()] = new Loader(); 
      dict["icon"+i.toString()].load(dict["iconFileReq"+i.toString()], context); 
      dict["icon"+i.toString()].x = -iconHeight/2; 
      dict["icon"+i.toString()].y = -iconWidth/2; 
      _map.putMarker(new Location(locXML.location.lat[i.toString()], locXML.location.long[i.toString()]), dict["locPointMarker"+i.toString()]); 
      trace("pm#: " + i + " xmlnodename: " + locXML.location.name[i.toString()] + " iconFL: " + dict["iconFileLink" + i.toString()] + " imgFL: " + dict["imageFileLink" + i.toString()]);    
      dict["locPointMarker"+i.toString()].mouseChildren=false; 
     } 
     } 
     }

對象類存儲由該鍵的toString（）屬性散列的值。因此，如果兩個鍵呈現爲相同的字符串，則這些值將發生衝突。

使用字典來代替。
