AS 2.0 RSS Objects

OOP RSS in Flash ActionScript 2.0


RSS keeps growing in popularity, and so we find ourselves playing with RSS feeds in new and interesting ways... or perhaps it's the other way around?!?!

Adobe (Formerly Macromedia) Flash is moving more and more towards XML and OOP paradigms. So I've taken it upon myself to write some classes for parsing through Flash's XML to get RSS feeds.

Q: What's this mean to me?
A: You can use my pre-written classes, to utilize RSS feeds inside of Flash.

Q: What can I do with this?
You can now make fun interfaces to interact with your favorite RSS Feeds.
A2: You can instantly update promotional information for your site, in all of your flash creations simultaneously.


EASY: Since most of the code is written already, you can get using it in just a few steps. 25 lines of code INCLUDING COMMENTS AND SPACES!

COMPLEX: For those of you who are interested in the insides of the objects, they are well documented, so have at them. If you augment them in any way, please let me know! Also give me credit plzthnx.

STEP 1: Initialization

On line 2 we set the path for the RSS URL. On line 3 we have another tested and true RSS feed for your testing purposes.

Starting at line 6 we instantiate 3 objects.
1) LINE 6: My parser class, which will parse the XML tree for us.
2) LINE 7: My RSS class, which will serve as the object that holds our info.
3) LINE 8: The inate Flash XML class, which will hold and load our RSS for parsing.

  1. /* Programmed by Gant Laborde */
  2. var URLofRSS = "http://www.BleachEatingFreaks.com/rss.php"
  3. //var URLofRSS = "http://www.digg.com/rss/index.xml"
  4. // Instantiate Objects
  5. var objRSSparse = new RSSparse; // rss parser
  6. var objRSS = new RSS; // rss class
  7. var xmlFeed:XML = new XML(); // Flash XML object

The Flash XML object has a property that will allow you ignore whitespace, and simplify processing. I set ignoreWhite to true.

  1. // set the ignoreWhite property to true (default value is false)
  2. xmlFeed.ignoreWhite = true;

We're going to set the XML to parse once it's done loading the page. So we override it's onload function on line 14.

On line 17, we use the parser to read the XML object that has finished loading. This gets read into the RSS object for our use!

On line 19 I then assign a textbox in the main stage to all the RSS file's contents. If you want to grab specific aspects the RSS object has the properties:

  • myTitle = The title of the RSS channel
  • myLink = The link to the site from the RSS feed
  • myDescription = RSS description
  • myLanguage = RSS language setting
  • myCopyright = RSS copyright
  • myItems = Array of Items in that channel. Where you are going to be most interested :D

Each item has it's own Title, Description and Link property.
To see in use, feel free to delve into the RSS object's printProperties() function.

  1. // Load and parse
  2. xmlFeed.onLoad = function(success) {
  3. // take XML and make it an RSS object
  4. objRSS = objRSSparse.createRSS(xmlFeed);
  5. _root.rssReceived = objRSS.printProperties();
  6. }; // end onLoad function


Line 25 uses the Flash XML object to load the given URL and you're done!

  1. // load the XML into the xmlFeed object
  2. xmlFeed.load(URLofRSS);

* This supports single part RSS like
* benxxx
* I did not write this to work for composite RSS like

In a cold calculus classroom awaiting a belligerent instructor, the outlandish conversations of life spawn. This is where Bleach Eating Freaks began. As students grouped together, common interests and quirks forged in scholastic stress invited the strange, and allowed for BEF to become a part of our lives. I am a Bleach Eating Freak.

» Description: Hmm... what to say about this one? It's reminiscent of the closing notes of the opening music from the Three Stooges done in a church organ style with a closing cymbal crash. I'll give this one away gratis, but feel free to check out my free loops and potential upcoming license-mandated ones over in the respective part of Flashkit.
