new to XML... problems parsing data

[boyzdynasty]

New to XML and just picked it up from the tutorial.
I'm just not getting the output I want.

here is the AS code in flash

data_xml = new XML();
data_xml.ignoreWhite = true;

data_xml.onLoad = function(sucess) {
        if (sucess) {
                processDATA(data_xml);
        }
};

data_xml.load('xmlResource.xml');

function processDATA(xml_data) {

        for (a in xml_data.firstChild.childNodes) {
                for (b in xml_data.firstChild.childNodes[a].firstChild.childNodes) {
                    trace("a=" + a +" b=" + b + " " + xml_data.firstChild.childNodes[a].firstChild.childNodes[b]);
                }
        }
}

I hoped to access the value and display it as...

a=1 b=0 <a href="http://www.temple.edu/counseling/services.html#casa" target="_blank"><font color="#FF0000">CASA</font></a>

a=1 b=3 <a href="http://www.temple.edu/counseling/services.html#sace" target="_blank"><font color="#FF0000">SACE</font></a>

a=1 b=2 <a href="http://www.temple.edu/disability/" target="_blank"><font color="#FF0000">Disability Services</font></a>

a=1 b=1 <a href="http://www.temple.edu/counseling/services.html#cert" target="_blank"><font color="#FF0000">CERT</font></a>

a=0 b=1 Oguntunde, Olusola

a=0 b=0 Ge, Yan

Any ideas as to why my output is...

// From the TRACE...
a=1 b=0 <a href="http://www.temple.edu/counseling/services.html#casa" target="_blank"><font color="#FF0000">CASA</font></a>
a=0 b=0 Ge, Yan

Ok...got it now...took 4ever!!

data_xml = new XML();

data_xml.ignoreWhite = true;

data_xml.onLoad = function(sucess) {
        if (sucess) {
                processBook(data_xml);
        }
};

data_xml.load('xmlResource.xml');

function processBook(xml_data) {
        // xmlDoc_xml is now a reference to the XML
        // object where our information is stored
        for (a in xml_data.firstChild.childNodes) {
                        for (var b=0; b < xml_data.firstChild.childNodes[a].childNodes.length; b++) {   
                    trace("a=" + a +" b=" + b + " " + xml_data.firstChild.childNodes[a].childNodes[b].firstChild);
                }
        }
}
