    AS2 - Need help with importing text from XML

    I can't seem to figure out why only one out of the five text fields show when I export my fla. The title and images work fine but none of the other descriptors are not working. What am I doing wrong? I checked my instance names and they all match. I've tried using .text and .HTMLText in the AS and nothing. Any help would be greatly appreciated.

    Code:
    imagesXML.onLoad = function() {
    	images = this.firstChild.childNodes;
    	for (var i = 0; i<images.length; i++) {
    		imgPaths.push(images[i].attributes.path);
    	}
    	totalImages = imgPaths.length;
    	autoSS = this.firstChild.attributes.slideshow == "true" ? 1 : 0;
    	intervalSS = parseInt(this.firstChild.attributes.interval)*1000;
    	galleryTitle = this.firstChild.attributes.title;
    	client_txt.text = this.firstChild.childNodes[0].attributes.client;
    	description_txt.text = this.firstChild.childNodes[0].attributes.description;
    	state_txt.text = this.firstChild.childNodes[0].attributes.state;

    Thanks Dawsonk but it still isn't working. Any other thoughts?
    Thanks!

    What are the output results when adding the traces below?
    Code:
    imagesXML.onLoad = function() {
    	images = this.firstChild.childNodes;
    	for (var i = 0; i<images.length; i++) {
    		imgPaths.push(images[i].attributes.path);
    	}
    	totalImages = imgPaths.length;
    	autoSS = this.firstChild.attributes.slideshow == "true" ? 1 : 0;
    	intervalSS = parseInt(this.firstChild.attributes.interval)*1000;
    	galleryTitle = this.firstChild.attributes.title;
    	trace(client_txt.text);
    	trace(this.firstChild.childNodes[0]);
    	client_txt.text = this.firstChild.childNodes[0].attributes.client;
    	description_txt.text = this.firstChild.childNodes[0].attributes.description;
    	state_txt.text = this.firstChild.childNodes[0].attributes.state;
    	XMLLoaded = true;
    };
    Can you post the missing code for the functions...
    Code:
    loadImage(0);
    navigation.changeImgShow();
    loading.SHLoading("hide");

    Okay, here's what the trace returned:

    Code:
    undefined
    <image path="atrium/atrium1.jpg" client="SCF Arizona - Accounting &amp; Finance Department" description="Interior Remodel - 8,000 sf" state="Phoenix, Arizona" />

    So, it looks like the AS is okay but something is wrong with the XML?


    Here's the code for the functions
    Code:
    // -- Load Imagers -- //
    function loadImage(image:Number):Void {
    	MCLs[image].loadClip(imgPaths[image], targets[image]);
    }
    
    loadList.onLoadComplete = function(evn:Object) {
    	var loadedImg:Number = parseInt(evn._name.substr(6, 1));
    	imgLoaded[loadedImg] = 1;
    	if (loadedImg < totalImages) {
    		loadImage(loadedImg + 1);
    	}	
    }
    
    
    
    // -- Switch Images -- //
    function switchImages(hideImg:Number, showImg:Number):Void {
    	if (imgLoaded[showImg]) {
    		var hideTw:Tween = new Tween(targets[hideImg],  "_alpha", none, targets[hideImg]._alpha, 0, 20, false);
    		var showTw:Tween = new Tween(targets[showImg],  "_alpha", none, targets[showImg]._alpha, 100, 20, false);
    		CSI = showImg;
    		navigation.changeImgShow();
    	} else {
    		loading.SHLoading("show");
    		var hideTw:Tween = new Tween(targets[hideImg],  "_alpha", none, targets[hideImg]._alpha, 0, 20, false);
    		if (CSI == totalImages - 2) {						// Check for the last Image.
    			navigation.nextBtn.action("disable");			// Only by nextBtn disable.
    		}
    		navigation.changeImgShow();
    		onEnterFrame = function() {
    			if (imgLoaded[showImg]) {
    				loading.SHLoading("hide");
    				var showTw:Tween = new Tween(targets[showImg],  "_alpha", none, targets[showImg]._alpha, 100, 20, false);
    				CSI = showImg;
    				navigation.changeImgShow();
    				delete this.onEnterFrame;
    			}
    		}
    	}
    }
    
    
    
    // -- Navigation -- //
    Mouse.addListener(navList);
    
    //var initSleep = setInterval(checkSleep, 1500);
    
    //navList.onMouseMove = function() {
    //	if (sleep) {
    //		if (navigation._y != 268) {
    //			navMove(268);
    //		sleep = false;
    //	}
    //}
    
    //function checkSleep():Void {
    //	if (sleep && !onFocus) {
    //		navMove(300);
    //	} else {
    //		sleep = true;
    //	}
    //}
    
    //function navMove(newY:Number):Void {
    //	var moveNavTw:Tween = new Tween(navigation, "_y", Strong.easeInOut, navigation._y, newY, 15, false);
    //}
    
    function prevImg():Void {
    	if (imgLoaded[0] && CSI != 0) {
    		switchImages(CSI, CSI-1);
    		if (Math.round(navigation.nextBtn.arr._alpha - navigation.enAlpha)) {	// Activation Check
    			navigation.nextBtn.action("enable");
    		}
    		if (CSI == 0) { 									// Check for the first Image
    			navigation.prevBtn.action("disable");
    		}
    	}
    }
    
    function nextImg():Void {
    	if (imgLoaded[0] && CSI < totalImages - 1) {
    		switchImages(CSI, CSI+1);
    		if (Math.round(navigation.prevBtn.arr._alpha - navigation.enAlpha)) {	// Activation Check
    			navigation.prevBtn.action("enable");
    		}
    		if (CSI == totalImages - 1) {						// Check for the last Image
    			navigation.nextBtn.action("disable");
    		}
    	}
    }
    
    function nextImgSS():Void {
    	if (imgLoaded[0]) {
    		if (CSI == totalImages - 1) {
    			switchImages(CSI, 0);
    		} else {
    			switchImages(CSI, CSI+1);
    		}
    		
    		if(CSI == totalImages - 1) {
    			navigation.nextBtn.action("disable");
    		} else if (CSI == 0) {
    			navigation.prevBtn.action("disable");
    			navigation.nextBtn.action("enable");
    		} else {
    			if (Math.round(navigation.prevBtn.arr._alpha - navigation.enAlpha)) {	// Activation Check
    				navigation.prevBtn.action("enable");
    			}
    		}
    	}
    }
    Thanks!

    The result of the first trace statement 'undefined' is telling you that it can't find the text field, so check the path and spelling.

    The result of the second trace statement is as expected, so the XML appears to be fine.

    Okay, I think I found the culprit. There's actions on the navigation and I think I need to add the text fields to it. I took a stab at it and at least get an "undefined" showing where one of the text fields is. I'm a little confused about the Parent / child relationship though. I think client, description and state are a child of Gallery??

    Code:
    var disAlpha:Number = 20;
    var enAlpha:Number = 60;
    var ovAlpha:Number = 90;
    
    
    /*-----*/
    base.onRollOver = function() {
    	_root.onFocus = true;
    }
    
    base.onRollOut = function() {
    	_root.onFocus = false;
    }
    
    base.useHandCursor = false;
    
    /*-----*/
    
    prevBtn.arr._alpha = disAlpha;
    prevBtn.enable = false;
    nextBtn.enable = true;
    
    galleryTitle.text = _parent.galleryTitle;
    client_txt.text = _parent.client_txt;
    description_txt.text = _parent.description_txt;
    state_txt.text = _parent.state_txt;
    //imgShow.text = "Image 1 / " + _parent.totalImages; 
    
    prevBtn.onRelease = function() {
    	_parent.prevImg();
    }
    
    nextBtn.onRelease = function() {
    	_parent.nextImg();
    }
    
    function changeImgShow() {
    	imgShow.text = "Image " + String(_parent.CSI + 1) + " / " + _parent.totalImages;
    }
    
    SWBtn.onRelease = function() {
    	tick.changeTick();
    }
    
    SWBtn.onRollOver = function() {
    	_root.onFocus = true;
    }
    
    SWBtn.onRollOut = function() {
    	_root.onFocus = false;
    }
    Thanks!
