Alright, so we’ll be dynamically generating a UI interface from an XML. So I’ll show you the XML first:

<mx:XML id="xml_save">
<cfg>
   <checkbox id="ebay" enabled="true" description="eBay"/>
   <checkbox id="wikipedia" enabled="false" description="wikipedia"/>
   <checkbox id="pandora" enabled="true" description="pandora"/>
   <checkbox id="flexr" enabled="false" description="flexr"/>
</cfg>
</mx:XML>

Now for each of the shortcut node in the XML above, we’re going to create a checkbox for each of them, style it, then see whether its checked or not (and display it), and then add it to a VBox called ‘p_CheckContainer‘.

private function updateForm(xml_result:XML):void {
   for each (var node:Object in xml_result.checkbox) {
       var checkBox:CheckBox = new CheckBox();        // new checkbox for each node
       checkBox.setStyle('paddingLeft', 30);          // style it 
       checkBox.label = node.@description;            // add it's label
       checkBox.selected = TypeConverter.parseBoolean*(node.@enabled); // un/checked
       checkBox.id = node.@id;                        // identify it
   p_CheckContainer.addChild(checkBox);               // display it
   }
}

* TypeConverter is a class with static public method parseBoolean which returns a true/false boolean.

Now, After we generated the UI from the XML, we want to save any changes, say for example, the user un/checked one of these checkboxes, and we want to resave the new XML with the appropriate values:

private function saveChanges():void {
   var _numCheckboxes:Number = p_CheckContainer.numChildren; // Number of CheckBoxes
   m_modifiedXML = <cfg></cfg>;                              // member var of type XML
   for (var i:Number= 0; i <= _numCheckboxes - 1; i++) {
       var _checkBox:CheckBox = p_CheckContainer.getChildAt(i) as CheckBox;
       var _newNode:XML = <shortcut/>;
           _newNode.@id= _checkBox.id;
           _newNode.@enabled = _checkBox.selected;
       m_modifiedXML.appendChild(_newNode);      
    }
    trace ("m_modifiedXML: " + m_modifiedXML);
}

To assure dominance of internet rich multimedia, Adobe and Time Warner are announcing Tuesday they have formed an online video alliance.

They’ll work on finding solutions for issues like digital rights management, audience measurement and content discovery and monetization.

Much of the relationship will concern backend technology for video creation that that the public will never see, Adobe said, however some implementations are already out there today, for instance CNN’s advanced application of Flash for its Obama Inauguration coverage and the recently relaunched TheWB.com.
