    ComboBox to Load New XML file

      I have an XML file containing a node with a reference to another XML file. I am trying to load the first XML file into a ComboBox. When the user makes a selection, the new XML file will load into a TileList/VBox. I cannot figure out how to pass the XML file referenced from the user's selection and display the results of that new XML file .

      So this is the flow:

      1. User chooses the catalog they would like to view from a CombBox (which is populated by an XML file)
      2 The Catagories referenced in #1 additionally point to another .xml file
      3. The user chooses from the ComboBox
      4. The appropriate XML file is passed and displayed in a TileList/VBox

      i hope i am making sense...

          Do you mean something like this:

          --- Main file: ---

          <?xml version="1.0" encoding="utf-8"?>
          <mx:Application xmlns:mx=" http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="loadNewCategory(category.selectedItem)">
          <mx:Label x="10" y="10" text="Pick a category of products to browse:"/>
          <mx:ComboBox dataProvider="{categoryData.category}" labelField="@name" x="245" y="8" width="140" id="category" change="loadNewCategory(category.selectedItem)"></mx:ComboBox>
          <mx:Label x="10" y="36" text="Products in the '{category.selectedItem.@name}' category:"/>
          <mx:List x="10" y="62" width="375" height="271" dataProvider="{productData.product}" labelField="@name"></mx:List>

          <mx:XML id="categoryData" source="categories.xml" />

          public var productData:XML;

          private function loadNewCategory(category:Object):void
          var loader:URLLoader = new URLLoader(new URLRequest(category.@file));
          loader.addEventListener(Event.COMPLETE, function(e:Event):void
          productData = XML(loader.data);

          --- categories.xml: ---

          <?xml version="1.0" ?>
          <category name="cheap" file="cheap.xml" />
          <category name="cool" file="cool.xml" />
          <category name="fast" file="fast.xml" />

          --- cheap.xml: ---

          <?xml version="1.0" ?>
          <product name="pen" />
          <product name="pencil" />
          <product name="cardboard box" />
          <product name="newspaper" />

          --- cool.xml: ---

          <?xml version="1.0" ?>
          <product name="iPod" />
          <product name="TiVo" />

          --- fast.xml: ---

          <?xml version="1.0" ?>
          <product name="Mustang" />
          <product name="Miata" />
          <product name="Thunderbird" />
