var found;
var searchFiles:Array = [“washbasins.xml”, “bathtubs.xml”];
//
function searchXML(searchVar) {
for (var j = 0; j<searchFiles.length; j++) {
var s:XML = new XML();
s.ignoreWhite = true;
s.load(searchFiles[j]);
s.onLoad = function() {
var searchCurrent:Array = this.firstChild.childNodes;
for (var i = 0; i<searchCurrent.length; i++) {
if (searchVar == searchCurrent*.attributes.item_txt) {
found = searchCurrent*.attributes.item_txt;
//trace(searchCurrent*.attributes.item_txt);
