Order Diazepam Without A Prescription

   If I wanted to pull an mp3 from an xml file and know I need to replace

   var url:String = "http://www.helpexamples.com/flash/sound/song2.mp3";

   I’ve been trying to use the following code (item_url is in my xml file)

   // ActionScript 2.0
   var item_url:Sound = new Sound();
   item_url.loadSound(url,true);

   Any advice will be appreciated. :)

   Ack, sorry for the nonsensical first sentence. I meant to say that I want to pull a dynamic mp3 from an xml file. I’m working on a slideshow and have audio that corresponds to each photo.

   Andrew Koop,

   What does the XML file look like?

   Thanks for your reply. XML is as follows:

   <item filename="slide1.jpg"
       title="Indiana University Michael Maurer School of Law"
       description="Dean Lauren Robel, IU Foundation President Gene Tempel, Janie Maurer, Michael S. “Mickey” Maurer, and IU President Michael McRobbie sign the gift agreement."
       name=""
       url="a_new_name.mp3">

   There are 15 items laid out in this same way. Does that help give an idea?

   Andrew Koop,

   OK, well, the url and filename are XML attributes, so you’d need to prefix the attribute name with a “@”. For example, the following code will loop over the item nodes in the XML and trace the @filename, @title, and @url attributes:

   // ActionScript 3.0
   var itemsXML:XML = <items>
               <item filename="slide1.jpg"
                       title="Title 1"
                       description="Description 1"
                       name=""
                       url="audio1.mp3" />
               <item filename="slide2.jpg"
                       title="Title 2"
                       description="Description 2"
                       name=""
                       url="audio2.mp3" />
               <item filename="slide3.jpg"
                       title="Title 3"
                       description="Description 3"
                       name=""
                       url="audio3.mp3" />
           </items>;
    
   var idx:uint;
   var len:uint = itemsXML.item.length();
   var node:XML;
    
   for (idx = 0; idx < len; idx++) {
       node = itemsXML.item[idx];
       trace(node.@title, "|", node.@filename, "|", node.@url);
   }

   Which displays the following output:

   Title 1 | slide1.jpg | audio1.mp3
   Title 2 | slide2.jpg | audio2.mp3
   Title 3 | slide3.jpg | audio3.mp3

   So depending on how you’re loading the XML and looping over the nodes, your code may look something like the following:

   var mp3_url:String = node.@url;
    
   var item_url:Sound = new Sound();
   item_url.loadSound(mp3_url, true);

   Thanks so much! I’ll give it a try. :)

   I’ve replaced the old with this

   // ActionScript 2.0
   item.fm_button.onRelease = function() {
       var mp3_url:String = node.@url;
       var item_url:Sound = new Sound();
       item_url.loadSound(mp3_url, true);
   }

   and I’m getting fieldname and unexpected } encountered errors. I’ve added the XML that you posted to the end of the file.

   Any ideas?

   Thanks :)

   Would it be easiest if I posted my whole actionscript layer?

   Sorry,

   For some reason I assumed we were all using ActionScript 3.0 (although that loadSound() should have tipped me off).

   Let me see if I can figure out how to do this easily in ActionScript 2.0… [dramatic pause]

   OK, this should work. I copied the XML into an external file, items.xml, and saved the .FLA and .XML files in the same directory.

   // ActionScript 2.0
   var itemsXML:XML = new XML();
   itemsXML.ignoreWhite = true;
   itemsXML.onLoad = itemsXML_onLoad;
   itemsXML.load("items.xml");
    
   function itemsXML_onLoad(success:Boolean):Void {
       if (!success) {
           trace("Unable to load/parse XML. Aborting.");
           return;
       }
    
       var idx:Number;
       var len:Number = itemsXML.firstChild.childNodes.length;
       var node:XML;
    
       for (idx = 0; idx < len; idx++) {
           node = itemsXML.firstChild.childNodes[idx];
           trace(node.attributes.title + " | " + node.attributes.filename + " | " + node.attributes.url);
       }
   }

   Running that should output the same results as our ActionScript 3.0 example;

   Title 1 | slide1.jpg | audio1.mp3
   Title 2 | slide2.jpg | audio2.mp3
   Title 3 | slide3.jpg | audio3.mp3

   So now if you wanted to get to a certain node’s url attribute, you could probably do something like the following:

   // ActionScript 2.0
   item.fm_button.onRelease = function() {
       var mp3_url:String = itemsXML.firstChild.childNodes[idx].attributes.url;
       var item_url:Sound = new Sound();
       item_url.loadSound(mp3_url, true);
   }

   The only real “gotcha” is that you’d need to have some “idx” variable somewhere tracking which child node index you wanted in the XML file.

   Hope that helps,
   Peter

    Hey, sorry. I should have mentioned that I am using 2 for this file. I’ll give this a whirl. Thanks again. I really appreciate your help.

    My apologies for the super amount of code here, but I think this might help explain what I have going on in the file. I’ve inserted your actionscript, but I’m thinking I only need a portion of it. Would you mind taking a looking and letting me know what you think?

    Ok I am making mp3 players. http://www.nukethemes.info as you can see they work ok using an xml file. What i am wondering is there a way to code it to where I can set it to automatically pull the names of the files from a folder sitting on the site and just display the info with out using an xml file or php and sql. I basically want to be able to just upload a file to the music folder and the flash to know to read the file name and display it.

    Hi,

    I’m getting No policy files granted access error (firefox) and tags are not showing (IE and Firefox).
    I’ve tried putting crossdomain.xml on the same place as swf file (root).
    still not working.

    I even used soundcontext with CheckPolicy attribute set to True.

    Have you experienced this problem??

    Thanks

    same problem as above :(

    My music are hosted on a free domain, webs.com
    So, when I upload an crossdomain.xml, it is substitued by their own crossdomain.xml
