    XML Slideshow Not AUTOMATICALLY with XML change. Help!!!

    This may seem simple, but I'm having a hard time getting this XML slideshow to auto-update when the XML is changed. Any ideas? Am I missing something? I've tried the time stamps like the following, with no success...

    xmlData.load("swfs.xml?vers="+new Date().getTime());

    Here's a link to download the entire package:
    http://www.brianmichaelis.com/xml_slideshow.zip (772kb)

    Getting this to auto-update would be much appreciated!

    If you don't want to download the package, here's the grunt of the AS:

    PHP Code:

    #include "mc_tween2.as"
    Stage.scaleMode "noscale";

    ///////////////////////////////////////

    function fadeIn(){
    container._alpha 0;
    container.alphaTo(100,3,"easeOutExpo");
    }
    function 
    fadeOut(){
    container.alphaTo(0,3,"easeOutExpo");
    }

    // Load XML
    function loadXML(loaded) {

    are you testing with the xml file online ?
    appended variables (time stamp) will fail if testing off HD

    upload swfs.xml and test with -
    xmlData.load("http://www.domain/swfs.xml?vers="+new Date().getTime());

    Yes - I just tested this online, with no success. Updating the XML and loading it to the server, doesn't change the swf withing the container automatically. When I refresh the HTML - then it updates....

    Any thoughts?

    Ok - I've found a temporary solution to this problem. I'm basically looping the 'container' - with a blank frame at the begining the timeline (which unloads the swf and reloads it, after looking at the updated XML. This created a small glitch, so I duplicated the the 'container2' and put the blank frame at the end of the timeline. Seems to work seemlessly, however there must be a 'cleaner' work around for this? Ideas?

    have a look in the Help files at setInterval
    place your xml load in a function. call the function with setInterval

    loadInt = setInterval(xmlLoad, 5000); // 1000 msecs = 1 second

    Found some information here:
    http://www.kirupa.com/developer/mx20...slideshow3.htm

    However, I'm not sure were to place the setInterval in my code? I need the swfs to update immediately when the XML changes.

    Thanks for your help in advance.

    I still can't seem to get this working. This should be a simple... update the XML and the swf immediately changes.

    I think the real problem, is that I can't get the current SWF to unload after an XML change...

    Any ideas? I'm totally burnt trying to look for a solution to this.

    Thanks for the link, however it's not exactly what I'm looking for. For example (and maybe to clarify things):

    XML is running this:

    PHP Code:
    <?xml version="1.0" encoding="iso-8859-1"?>
    <swf>
        <swiff>
            <id>swf1.swf</id>
        </swiff>
    </swf>
    And I update to this:

    PHP Code:
    <?xml version="1.0" encoding="iso-8859-1"?>
    <swf>
        <swiff>
            <id>swf2.swf</id>
        </swiff>
    </swf>
    I would like the current (swf1.swf) to update immediatly to (swf2.swf). The problem I'm having is that it just keeps playing (swf1.swf). It doesn't unload it on the xml update.

    You see?

    i have tested this offline, when i change the content of the xml file (as per your above post) the main file loads the new swf file to movieclip- container.
    can you make use of the method ?

    PHP Code:
    loadInt setInterval(xmlLoad5000); 

    function 
    xmlLoad(){
    xmlData = new XML(); 
    xmlData.ignoreWhite true
    xmlData.onLoad loadSWF
    xmlData.load("swiff.xml"); 
    };

    function 
    loadSWF(){
    toLoad this.firstChild.firstChild.firstChild.childNodes;
    container.loadMovie(toLoad);
    };

    toLoad this.firstChild.firstChild.firstChild.childNodes;
    container.loadMovie(toLoad);
    }; 
    Sorry for the slow response here. Was tied down with some other projects. This method DOES work, however I get a 'flicker' everytime the SWF reloads. I'm trying to make this a seamless as possible. Is there anyway to update the xml, and replace the SWF without the flicker?
