That looks ok.
Did the trace show what you expect? If you think so, then move in on the data you want one step at a time: var xmlTemp:XML = xmlResult.projects; trace(xmlTemp.toXMLString()); //does this show the products node? var xlProjects:XMLList = xmlTemp.project; trace(xlProjects.length); //is this the expected number? //finally projectHolder = new XMLListCollection(xlProjects); trace(projectHolder.length); Tracy ________________________________ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Mark Sent: Friday, September 28, 2007 2:36 PM To: [email protected] Subject: [flexcoders] Re: I really need some help on how to display details of a record -arrayCollection I've actually never used XMLListCollection so I'm giving it a shot.
