XML class 213

When sendAndLoad() is executed, the XML object property loaded is set to false. When

the XML data finishes downloading, the

loaded property is set to true if the data

successfully loads and the

onLoad event handler is invoked. The XML data is not parsed until

it is completely downloaded. If the XML object previously contained any XML trees, they are

discarded.

Example

The following example includes ActionScript for a simple e-commerce storefront application.

The

XML.sendAndLoad() method transmits an XML element that contains the user’s name

and password and uses an

onLoad handler to process the reply from the server.

var login_str = "<login username=\""+username_txt.text+"\"

password=\""+password_txt.text+"\" />";

var my_xml = new XML(login_str);

var myLoginReply_xml = new XML();

myLoginReply_xml.ignoreWhite = true;

myLoginReply_xml.onLoad = myOnLoad;

my_xml.sendAndLoad("http://www.flash-mx.com/mm/login_xml.cfm",

myLoginReply_xml);

function myOnLoad(success) {

if (success) {

if ((myLoginReply_xml.firstChild.nodeName == "packet") &&

(myLoginReply_xml.firstChild.attributes.success == "true")) {

gotoAndStop("loggedIn");

} else {

gotoAndStop("loginFailed");

}

} else {

gotoAndStop("connectionFailed");

}
