Help with my XML....Pease.

[StevieG35]

I created a simple xml in notepad that will display a news headline and URL (when available). What is happening is after the first time it runs through perfectly, then on the second run through is where things got a bit strange. If I do not have a URL attached to the headline that is being displayed, it used the last URL it had, until a new one is read. Is there a way to clear out the URL? I am still learning a lot. I am using Flash 8 Pro. Actionscrip 2. Below is my actionscript, please let me know if I need to move this thread elsewhere. Thanks you in advance.

function loadXML(loaded) {
if (loaded) {
xmlNode = this.firstChild;
caption = [];
url = [];
total = xmlNode.childNodes.length;
for (i=0; i<total; i++) {
caption[i] = xmlNode.childNodes[i].childNodes[0].firstChild.nodeValue;
url[i] = xmlNode.childNodes[i].childNodes[1].firstChild.nodeValue;
}
first_item();
} else {
content = "file not loaded!";
}
}
xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;
xmlData.load("http://static.cbslocal.com/station/wcco/ticker/news.xml?blarg="+new Date().getTime());
//
function first_item() {
delay = 6500;
p = 0;
display(p);
p++;
}
function timer() {
myInterval = setInterval(ticker, delay);
function ticker() {
clearInterval(myInterval);
if (p == total) {
p = 0;
}
fadeout();
}
}
function display(pos) {
over = new TextFormat();
over.underline = true;
//
out = new TextFormat();
out.underline = false;
//
newsMC.newsText._alpha = 100;
newsMC.newsText.text = caption[pos];
if (url[pos] != null) {
newsMC.onRelease = function() {
getURL(url[pos], "_blank");
};
}

if (url[pos] != null) {
newsMC.onRollOver = function() {
this.newsText.setTextFormat(over);
};
}
if (url[pos] != null) {
newsMC.onRollOut = function() {
this.newsText.setTextFormat(out);
};
}
timer();
}
function fadeout() {
this.onEnterFrame = function() {
if (newsMC.newsText._alpha>=0) {
newsMC.newsText._alpha -= 5;
} else {
display(p);
p++;
delete this.onEnterFrame;
}
};
}

[whispers]

its hard to read your code since you didnt format it..

but have you done a check to see if your URL var is 'undefined'?

and if so set your URL var = ""
