    Problem Reading XML - Help!

    I"m having issues defining values in my AS from the XML. For some reason my AS won't read my XML File. See below. Am I missing anything?

    I've been going through this for hours and can't figure out what I'm missing.

    AS:
    Code:
    
    var newsWidth=300;//news tricker width;
    var newsHeight=335;//news tricker height;
    var itemspace=15;//between two item space.
    var speed=40;//slide speed.
    
    system.useCodepage=true;
    Stage.scaleMode = "noscale";
    // -- draw rectangle
    MovieClip.prototype.drawrect = function(pos_x, pos_y, w, h) {
    	// --
    	this.px = pos_x;
    	this.py = pos_y;
    	this.an = w;
    	this.al = h;
    	// --
    	with (this) {
    		beginFill(0x000000, 30);
    		moveTo(px, py);
    		lineTo(px+an, py);
    		lineTo(px+an, py+al);
    		lineTo(px, py+al);
    		lineTo(px, py);
    		endFill();
    	}
    };
    // -- format text
    myFormat = new TextFormat();
    myFormat.font = "verdana";
    myFormat.size = 20;
    myFormat.color = 0x000000;
    
    
    // xml parsing.
    xmlParse = function (xmlObj) {
    	this = xmlObj;
    	var xpos = 0;
    	var ypos =0;
    	for (var i = 0; i<this.firstChild.childNodes.length; i++) {
    		item = newsTicker_mc.attachMovie("Ticker_mc", "Ticker"+i, 100+i);
    		//item.mytext.embedFonts = true;
    		item.main.mytext.autoSize = true;
    		item.main.mytext.text = this.firstChild.childNodes[i].attributes.mytext;
    		item.mylink = this.firstChild.childNodes[i].attributes.links;
    		item.main.mytext.setTextFormat(myFormat);
    		item._x = xpos;
    		item._y = ypos;
    		ypos += item.main.mytext.textHeight+itemspace;
    		// --
    		item.onRelease = function() {
    			this.main.mytext.textColor = 0x000000;
    			// -- open the link
    			getURL(this.mylink, target="_blank");
    		};
    		// --
    		item.onRollOver = function() {
    			this.news.mytext.textColor = 0x000000;
    			// --clear interval
    			clearInterval(idInterval);
    		};
    		// --
    		item.onRollOut=item.onReleaseOutside = function() {
    			this.main.mytext.textColor = 0x000000;
    			// -- re setInterval,go on move
    			idInterval = setInterval(scrollit, speed, this._parent);
    		};
    	}
    };
    
    // --load xml
    myXML = new XML();
    myXML.ignoreWhite = true;
    myXML.onLoad = function(succes) {
    	if (succes) {
    		xmlParse(this);
    	} else {
    		trace("Error al cargar datos");
    	}
    };
    
    myXML.load("http://tabletrac/tv/text/L.xml");
    
    // --define scroll
    scrollit = function (myclip) {
    	myclip._y -= 1;
    	updateAfterEvent();
    	// -- hitTest
    
    	if (!myclip.hitTest(maskTicker)) {
    		myclip._y = maskTicker._y+maskTicker._height+50;
    	}
    };
    
    // -- create mask
    this.createEmptyMovieClip("maskTicker", this.getNextHighestDepth());
    this.maskTicker.drawrect(newsTicker_mc._x, newsTicker_mc._y, newsWidth, newsHeight);
    newsTicker_mc.setMask(this.maskTicker);
    // -- setInterval
    
    idInterval = setInterval(scrollit, speed, newsTicker_mc);

    <new links is there actually a space there?

    XML Naming Rules

    XML elements must follow these naming rules:

    * Names can contain letters, numbers, and other characters
    * Names must not start with a number or punctuation character
    * Names must not start with the letters xml (or XML, or Xml, etc)
    * Names cannot contain spaces

    unless its a typo your xml is poorly formed at this line
    </news>-->

    in Flash, with the barest minimum of code, i can show
    each of the attributes within the nodes with -

    PHP Code:
    // xml parsing.
    xmlParse = function (xmlObj) {
    aNode xmlObj.firstChild.firstChild.childNodes;
    for (var 
    0i<aNode.lengthi++) {
    trace(aNode[i].attributes.mytext);
    trace(aNode[i].attributes.links);
    }
    };

    Yes - I left a space in there because I'm not wanting to link anthing just yet. I am however stumped on why it's not loading the XML - specifically for a node like this:

    Code:
    :)item.main.mytext.setTextFormat(myFormat);
    when I load the line without "main" and remove "main" from the XML it work - but I want "main" in the XML, because I need to add an additional tag. So I guess the question is whe I add "main" to my xml - how can i make it work with the current code above?

    Again - thank you for the help. This is driving me insane!

    }
    }; 
    hth

    I don't under stand what you gave me?

    Here's the AS code that works perfectly with the XML above:

    Code:
    var newsWidth=300;//news tricker width;
    var newsHeight=375;//news tricker height;
    var itemspace=15;//between two item space.
    var speed=40;//slide speed.
    
    system.useCodepage=true;
    Stage.scaleMode = "noscale";
    // -- draw rectangle
    MovieClip.prototype.drawrect = function(pos_x, pos_y, w, h) {
    	// --
    	this.px = pos_x;
    	this.py = pos_y;
    	this.an = w;
    	this.al = h;
    	// --
    	with (this) {
    		beginFill(0x000000, 30);
    		moveTo(px, py);
    		lineTo(px+an, py);
    		lineTo(px+an, py+al);
    		lineTo(px, py+al);
    		lineTo(px, py);
    		endFill();
    	}
    };
    // -- format text
    myFormat = new TextFormat();
    myFormat.font = "verdana";
    myFormat.size = 20;
    myFormat.color = 0x000000;
    
    
    // xml parsing.
    xmlParse = function (xmlObj) {
    	this = xmlObj;
    	var xpos = 0;
    	var ypos =0;
    	for (var i = 0; i<this.firstChild.childNodes.length; i++) {
    		item = newsTicker_mc.attachMovie("Ticker_mc", "Ticker"+i, 100+i);
    		
    		//item.mytext.embedFonts = true;
    		item.mytext.autoSize = true;
    		item.mytext.text = this.firstChild.childNodes[i].attributes.mytext;
    		item.mylink = this.firstChild.childNodes[i].attributes.links;
    		item.mytext.setTextFormat(myFormat);
    		item._x = xpos;
    		item._y = ypos;
    		ypos += item.mytext.textHeight+itemspace;
    		// --
    		item.onRelease = function() {
    			this.mytext.textColor = 0x000000;
    			// -- open the link
    			getURL(this.mylink, target="_blank");
    		};
    		// --
    		item.onRollOver = function() {
    			this.mytext.textColor = 0x000000;
    			// --clear interval
    			clearInterval(idInterval);
    		};
    		// --
    		item.onRollOut=item.onReleaseOutside = function() {
    			this.mytext.textColor = 0x000000;
    			// -- re setInterval,go on move
    			idInterval = setInterval(scrollit, speed, this._parent);
    		};
    	}
    };
    
    // --load xml
    myXML = new XML();
    myXML.ignoreWhite = true;
    myXML.onLoad = function(succes) {
    	if (succes) {
    		xmlParse(this);
    	} else {
    		trace("Error al cargar datos");
    	}
    };
    
    myXML.load("http://tabletrac/tv/text/L.xml");
    
    // --define scroll
    scrollit = function (myclip) {
    	myclip._y -= 1;
    	updateAfterEvent();
    	// -- hitTest
    
    	if (!myclip.hitTest(maskTicker)) {
    		myclip._y = maskTicker._y+maskTicker._height+50;
    	}
    };
    
    // -- create mask
    this.createEmptyMovieClip("maskTicker", this.getNextHighestDepth());
    this.maskTicker.drawrect(newsTicker_mc._x, newsTicker_mc._y, newsWidth, newsHeight);
    newsTicker_mc.setMask(this.maskTicker);
    // -- setInterval
    
    idInterval = setInterval(scrollit, speed, newsTicker_mc);
    What I need to do is add <main> </main> to my XML file - which renders my AS useless - how do I modify the myText to read with the addition of main?

    Ok, but if the XML is malformed, it probably wont load and even if it does, I am betting it wont parse correctly.

    It's parsing correctly. But I want to add a <main> at the top and an </main> at the bottom of the xml so i can add another xml call.

    Code:
    <news>
    
    <new links="" mytext="Welcome to 7 Clans Casino | Thief River Falls"/>
    <new links="" mytext="                                                                                    "/>
    <new links="" mytext="...................................."/>
    <new links="" mytext="Our friendly Player Club Staff are here to guarantee that you experience the best of Northern Minnesota's celebrated hospitality each time you visit us. "/>
    
    
    <new links="" mytext="Don't forget to sign-up for our Players Club! Jackpot will be starting at 4:00pm"/>
    <new links="" mytext="                                                                                    "/>
    <new links="" mytext="...................................."/>
    <new links="" mytext="Check out the pool"/>
    <new links="" mytext="                                                                                    "/>
    <new links="" mytext="...................................."/>
    <new links="" mytext="Lunch and Dinner Buffets starting at $11.95"/>
    <new links="" mytext="                                                                                    "/>

    if your xml is heading towards -
    PHP Code:
    <?xml version="1.0" encoding="UTF-8"?>
    <main>
    <news>
    <new links="link1" mytext="Welcome to 7 Clans Casino | Thief River Falls" />
    <new links="link2" mytext="Lunch and Dinner Buffets starting at $11.95" />
    </news>
    </main>

    <main>
    <news>
    <new links="link3" mytext="Thief River Falls" />
    <new links="link4" mytext="Lunch $110.95" />
    <new links="link5" mytext="Starting at 4:00pm" />
    </news>
    </main>
    you will need to loop thro' each <main></main> node counting the number of <new > nodes within each.
    you will need a nested loop to do this -
    PHP Code:
    // xml parsing.
    xmlParse = function (xmlObj) {
    aNode xmlObj.childNodes
    len1 aNode.lengthtrace(len1+" nodes - <main></main>");
        for (var 
    0i<len1i++) {
    len2 =  aNode[i].firstChild.childNodes.length; ;
        for (var 
    0j<len2j++) { trace("<main>"+i+" <new>"+j);
    trace(aNode[i].firstChild.childNodes[j].attributes.mytext);
    trace(aNode[i].firstChild.childNodes[j].attributes.links)
    }
    }
    };

    // --load xml
    myXML = new XML();
    myXML.ignoreWhite true;
    myXML.onLoad = function(){
    xmlParse(this);
    }
    myXML.load("test.xml");

    Again Mod Dog - Thank you for your help, however nothing comes up now... Did i post something wrong here? I'm trying to undersand how this works - as this is a test application - but I do have similar ones I'd like to do the same thing with....

    AS:

    Code:
    var newsWidth=300;//news tricker width;
    var newsHeight=375;//news tricker height;
    var itemspace=15;//between two item space.
    var speed=40;//slide speed.
    
    system.useCodepage=true;
    Stage.scaleMode = "noscale";
    // -- draw rectangle
    MovieClip.prototype.drawrect = function(pos_x, pos_y, w, h) {
    	// --

    pasting the code in your last post to a new fla and testing, outputs an error -

    Error opening URL "http://tabletrac/tv/text/L.xml"

    can you fix this so we are both testing with the same xml file ?

    Might be easier for you to just see my orignial code. Here's the link to the FLA document:

    http://www.intromotion.com/tv/promo/l_shape_OFFICE.fla

    I redirected the paths XML online. http://www.intromotion.com/tv/text/L.xml

    As you can see, what i"m trying to do is feed the ONE XML with 2 tags. The "L" file works well when i feed the XML's as 2 seperate files, however I'd like to try it with just one.

    On another note (and I've posted this in a new thread) when I change the XML file, nothing updates, unless I re-start the program.... This app outputs to EXE and runs on a desktop, but calls for the XML through http. Any suggestions?

    Thanks for the help!

    before you can get any further, you need to simplify
    that xml file. I suggest you follow this format -
    PHP Code:
     <?xml version="1.0" encoding="ISO-8859-1" ?>

    <main>

         <newsticker>

      <item>
        <news>User BEEEEEEE was here! 1</news> 
        <url></url> 
      </item>

      <item>
        <news>User BEEEEEEE was here! 2</news> 
        <url></url> 
      </item>

         </newsticker>

         <news>

      <item>
        <news>Welcome to 7 Clans Casino | Thief River Falls</news> 
        <url></url> 
      </item>

      <item>
        <news></news>
        <url></url> 
      </item>

      <item>
        <news>....................................</news> 
        <url></url> 
      </item>

          </news>

    </main>
    is this a possibility ?

    Yes! Not bad at all... when you test this (i.e. updating the XML) do you notice the ticker on the bottome starts to wig out? I'm wondering if a timeline might solve the issue? Any ideas?

    Agian - thanks much for the help on this.

    try clearing the setInterval within the refreshXML function,
    when the onLoad completes, restart the setInterval call.

    That didn't seem to work.... i just put the setinterval after the refreshXML right?

    Again - thanks for your help...

    I've been playing around with the set interval. The text totally wigs out when I update the XML - although it is updating... This exactly same thing happened when I added a timeline. I'm wondering if I need to unload and reload the XML somehow? Do you see this on your end?
