I am trying to call a functoin which will use the xml object to retrieve data and return the data to the function call. When I trace “test\_var” inside the “book\_xml.onLoad” functoin, it works. but I can pass the xml data out of the get\_data function. Can anyone help???

stop();

//define function  
function get\_data(id) {  
book\_xml = new XML();  
book\_xml.ignoreWhite = true;  
book\_xml.onLoad = function(sucess) {  
test\_var = book\_xml.firstChild.childNodes[0].childNodes[0].firstChild;  
};  
book\_xml.load(“school\_xml.asp?id=” + id);  
return test\_var;  
}

//call function and retriev value  
ret\_var = get\_data(“105”);

//trace value  
trace(ret\_var);
