News Ticker XML Filtering

[enormousrodent]

Hi there…i want to modify this code so that i can only show news items that are in a particular category…

here is my a/s

function  loadXML(loaded)  {
    if (loaded) {
        xmlNode = this.firstChild;
        articleTitle = [];
        articleContents = [];
        articleDate = [];
        articleCategory = [];
        articleLink = [];
        total = xmlNode.childNodes.length;
        trace(total);
        r = 0;
        for (i=0; i<total; i++) {
            if(xmlNode.childNodes*.childNodes[3].firstChild.nodeValue == "Sharepoint"){            
                trace(r);
                articleTitle* = xmlNode.childNodes*.childNodes[0].firstChild.nodeValue;
                articleContents* = xmlNode.childNodes*.childNodes[1].firstChild.nodeValue;
                articleDate* = xmlNode.childNodes*.childNodes[2].firstChild.nodeValue;
                articleCategory* = xmlNode.childNodes*.childNodes[3].firstChild.nodeValue;
                articleLink* = xmlNode.childNodes*.childNodes[4].firstChild.nodeValue;    
            }else
            {
                r++;
            }
        }
        total = (total-r);
        
        first_item();
        } else {        
            content = "file not loaded!";    
        }
} 

xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;
xmlData.load("news.xml");
//
function first_item() {
    delay = 5000;
    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;
    //
    titleMC.title_txt._alpha = 100;
    titleMC.title_txt.text = articleTitle[pos];
    
    contentMC.content_txt._alpha = 100;    
    contentMC.content_txt.text = articleContents[pos];
    
    dateMC.date_txt._alpha = 100;
    dateMC.date_txt.text = articleDate[pos];

    fadein();
    titleMC.onRelease = function() {
        getURL(articleLink[pos], "_self");
    };
    titleMC.onRollOver = function() {
        this.title_txt.setTextFormat(over);
        this.title_txt.setTextFormat(bolda);        
    };
    titleMC.onRollOut = function() {
        this.title_txt.setTextFormat(out);
    };
    timer();
}
function fadein() {
    this.onEnterFrame = function() {
        if (titleMC.title_txt._alpha < 100) {
            titleMC.title_txt._alpha += 5;
            contentMC.content_txt._alpha += 5;
            dateMC.date_txt._alpha += 5;
        } else {
            display(p);
            p++;
            delete this.onEnterFrame;
        }
    };
}

function fadeout() {
    this.onEnterFrame = function() {
        if (titleMC.title_txt._alpha>=0) {
            titleMC.title_txt._alpha -= 5;
            contentMC.content_txt._alpha -= 5;
            dateMC.date_txt._alpha -= 5;
        } else {
            display(p);
            p++;
            delete this.onEnterFrame;
        }
    };
}

and my XML

<?xml version="1.0"?>

<newsitems>
    <article>
        <name>Article Name Sharepoint</name>
        <contents>11111This is the article Contents This is the article contents.</contents>

    </article>
</newsitems>

you can see how i have done it so far but the new ticker still shows all items as undefined and others which do validate as the correct info…how do i get it to just show the items i want.

Thanks
