Call XML when button pressed

Question

I am pulling in some XML data that shows up in columns.
Currently it is working I think how I want it when testing, the
data is going to the correct column. What I want to do is extend
this so when a button is clicked the correct column data is shown.
var myXML:XML = new XML();
myXML.ignoreWhite = true;
myXML.load("rels.xml");
myXML.onLoad = function(success) {
if (!success) {
trace("XML FAILED TO LOAD");
} else {
trace("XML LOADED");
var totalButtons:Number =
myXML.firstChild.childNodes.length;
for (i=0; i<myXML.firstChild.childNodes.length; i++) {
trace(myXML.firstChild.childNodes
.attributes.id);
var columnData = myXML.firstChild.childNodes;
//this pulls the values for the columns
for (var j = 0; j<columnData.childNodes.length; j++) {
_root["c"+j+"_txt"].htmlText = columnData.childNodes[j];
XML is like this
<stuff>
<but id ="button1" >
<column id ="1">test 1</column>
<column id ="2">test 2</column>
<column id ="3">test 3</column>
</but>
</stuff>
I want to have a button for each node. So if I have five
nodes, I want to create 5 buttons. I know how to do this via
attachMovie from the library, but how do I tell it that button2 has
been clicked? Where do I do that in my code? I want it to be when
but2 is clicked it finds but2_mc ID in the XML and displays the
column text for that data.
initially I had this right before my for loop.
for (b=1; b<=totalButtons; b++) {
attachMovie("buttonSelection","but"+b,this.getNextHighestDepth());
Thanks for the help.

Thanks Dave. I feel I am almost there. the ind.b doesn't seem
to be working. I was able to get my button to work but using _root
instead of this. Any more pointers? Where does getMyXML(this.ind);
this go?
var myXML:XML = new XML();
myXML.ignoreWhite = true;
myXML.load("rels.xml");
myXML.onLoad = function(success) {
if (!success) {
trace("XML FAILED TO LOAD");
} else {
trace("XML LOADED");
var totalButtons:Number =
myXML.firstChild.childNodes.length;
//this determines the button
for (i=0; i<myXML.firstChild.childNodes.length; i++) {
trace(myXML.firstChild.childNodes
.attributes.id);//returns but1_mc, etc
var columnData = myXML.firstChild.childNodes;
//this pulls the values for the columns
for (var j = 0; j<columnData.childNodes.length; j++) {
_root["c"+j+"_txt"].htmlText = columnData.childNodes[j];
for (b=1; b<=totalButtons; b++) {
trace(totalButtons);
attachMovie("test","but"+b,this.getNextHighestDepth(),{ind:b});
_root["but"+b]._x = 0;
_root["but"+b]._y = yPosition;
yPosition = yPosition+25;
_root["but"+b].onRelease = function() {
getMyXML(this.ind);
trace("ind "+this.ind)
var yPosition = 0;
