Given the following XML:

<data_set>
  <data_item>
    <item_num>1
    <item_text>Test 1
  </data_item>
  <data_item>
    <item_num>2
    <item_text>Test 2
  </data_item>
  <data_item>
    <item_num>3
    <item_text>Test 3
  </data_item>
</data_set>

Now to find the maximum or minimum value for the node "item_num", below is a function to sort through the matching nodes of the specified element:

function findValue(xmlData:XMLList, nodeName:String, options:Object = null):String {
  //XMLList of all the nodes with the specified name
  //DATA_ITEM refers to the element name from our XML provided above 
  var col1:XMLList - new XMLList(xmlData.DATA_ITEMnodeName);
  //Temporary Array
  var temp:Array = new Array();
  
  //Add all the relevant node values to a temporary array
  for (var i:int = 0; i < col1.children().length(); i++) {
     tmp.push(col1i);
  }
  //Sort the Array with the options provided as a parameter to the function
  var sorted:Array = tmp.sort(options);
  //Return the first value in the sorted array
  return sorted0;
}

Now to use our function:

//xmlDataList is our incoming XML data from a file or source we have already parsed
trace ("Maximum Value: "+ findValue(xmlDataList, "ITEM_NUM", Array.DESCENDING|Array.NUMERIC));
trace("MIN Element1: " + findValue(xmlDataList, "ITEM_NUM", Array.NUMERIC));

After looking everywhere to try to figure out how to save data to an existing XML file, this is what I came up with:

//~~~~~~ IMPORT FLASH CLASSES
import flash.filesystem.*;

//~~~~~~ VARIABLE DECLARATION
var dataPathLocal:String = "com/frankgarofalo/data/"; //file path
var destinationFile:File = File.userDirectory; //Where to save the file on local computer
var sourceFile:File = File.createTempFile(); //Temporary File
var writeStream:FileStream = new FileStream(); //File Access
var xmlData:XML = new XML();

//~~~~~~ CODE
xmlData = 1; //XML Data
destinationFile = destinationFile.resolvePath(dataPathLocal);
//trace (destinationFile .exists);
//trace (destinationFile .nativePath);
//trace (destinationFile .url);

//Open File & Write to the File
writeStream.open(sourceFile, FileMode.WRITE);
writeStream.writeUTFBytes(xmlData);
writeStream.close();
sourceFile.copyToAsync(destinationFile, true);
sourceFile.addEventListener(Event.COMPLETE, dataSaved);	

function dataSaved(e:Event):void {
    trace ("~~~~~~ XML SAVED SUCCESSFULLY ~~~~~~");
}

Hopefully I didn't forget anything from copying over the code from my AS file. If I did or if you have any questions, please let me know. Here are some links for reference:

So I've been working with the ActionScript class RotatableScalable (which can be found on the NUI Group web site at: http://wiki.nuigroup.com/Building_Your_First_Multi-Touch_Application_in_Flash). However, I found a major flaw with that class that occurs when rotating an asset object that extends the RotatableScalable class. The object is rotated around its 0,0 coordinate (or in other words the top left corner of the asset). From preliminary testing, this proved to be very disorientating to users since the asset would spin away from the users' fingers.

Chris Yanc created a revised version of the RotatableScalable class called RotatableScalableRev which resolves that issue. For more details about his version, visit: http://www.cyancdesign.com/2009/05/understanding-rotatablescalable/

I'm so glad to get this working correctly now - thanks Chris! :D

I've been working on some ActionScript 3.0 code within Adobe Flash CS4. I needed to rotate a dynamic textfield but I was running into problems with the embedFont = true; code. I finally found a solution on an Adobe Developer Connection post titled "Embedded Fonts" under the Quick Start section (http://www.adobe.com/devnet/flash/quickstart/embedding_fonts/):

// Create a new instance of the Font1 symbol from the document's library.
var myFont:Font = new Font1();

/* Create a new TextFormat object, and set the font property to the myFont
   object's fontName property. */
var myFormat:TextFormat = new TextFormat();
myFormat.font = myFont.fontName;
myFormat.size = 24;

/* Create a new TextField object, assign the text format using the 
   defaultTextFormat property, and set the embedFonts property to true. */
var myTextField:TextField = new TextField();
myTextField.autoSize = TextFieldAutoSize.LEFT;
myTextField.defaultTextFormat = myFormat;
myTextField.embedFonts = true;
myTextField.text = "The quick brown fox jumped over the lazy dog.";
addChild(myTextField);

Very interesting work that Adobe is doing.

Adobe Wave is a new real-time notification system currently in Adobe Labs. Those who download the desktop application (which is an Adobe AIR app) can then subscribe to receive notifications from their favorite sites - more about Adobe Wave: http://labs.adobe.com/technologies/wave/

I was working on a web project and wanted to integrate the Adobe Wave service. After reviewing the REST API for Adobe Wave is was quite confused. Christian Grobmeier developed a WordPress plug-in for Adobe Wave (http://blog.grobmeier.de/2009/08/04/adobe-wave-wordpress-plugin-finished.html). After downloading and making some modifications to his PHP code I was able to get my web project to connect to the Adobe Wave services. Note: If you want to connect to the Adobe Wave services you must first apply/register for a publisher account: https://ps-wave.adobe.com/portal/PublisherAdmin.html

Here is a zip file to download: http://web.ics.purdue.edu/~fgarofal/examples/WaveIntegrationDemo.zip

In the below code example, you will need the PHP classes from the zip file in the link above. Also you will need to swap out "adobe_id" and "adobe_pass" with your Adobe account information once you have been approved as a publisher. Assuming you have an approved publisher account, then you can create a "feed" from the feed you will need to replace "URI" with the URI code you receive from the Wave Publisher Portal for that specific feed.

include('APIToken2.php');
include('WaveException.php');
include('BroadcastMessage.php');

//Prepare Post
$post_string = "Hello Adobe Wave";
$post_string = substr($post_string, 0, 140);
//Build Post
$post = array();
$post0->post_title = $post_string;
$post0->guid = "http://labs.adobe.com/technologies/wave/";

$result = waveIntegration_send('adobe_id','adobe_pass','URI', $post);

if ($result == true) {
	echo 'Success';
} else {
	echo 'Error';
}

//waveIntegration_send
//---------------------
//Input: string (username), string (password), array (post: string title, string url link)
//Output: bool (true - successful, false - error)
function waveIntegration_send($username, $password, $topic, $posts) {
	if($username == '' || $password == '' || $topic == '') {
		// no action - error would be nice
		return;
	}
	
	$title = $posts0->post_title;
	$link = $posts0->guid;
	
	$token = APIToken::getInstance($username, $password);
	$tokenValue = $token->getToken();
	
	$message = new BroadcastMessage(
					$tokenValue, 
					$topic, 
					$title, $link);
	$code = $message->send();
	if ($code >= 200 && $code < 300) {
		return true;
	} else {
		return false;
	}
}

The Adobe Integrated Runtime was launched by Adobe Systems in February 2008. Prior to the launch it was code-named Apollo. Adobe describes the AIR technology as a cross-operating system runtime that allows web application developers to use their existing web development skills (HTML, Javascript, Adobe Flash, Adobe Flex, Ajax) to build and deploy rich Internet applications to the desktop.
