Loading XML from PHP

Hi guys, I guess this is going to be easy.
Let’s say I am loading xml from convert.php. Can I do it by simply calling it like:


function loadXML(file) {
    xml = new XML();
    xml.ignoreWhite = true;
    xml.onLoad = function(success) {
        if (success) {
            trace("XML loaded");
        } else {
            trace("Warning! XML hasn't been loaded!");
        }
    };
    xml.load(file);
}
loadXML("convert.php"); //it is of course in same folder

Thanks for answers!
