</mx:XML>
public function getCourseTitle(instanceID:Number){ if([EMAIL PROTECTED]){ // Found the bastard :-)
// Iterate through each Node of the XML
for each(var parentNodes:XML in theCatalog.trainingEvent){
var childNodes:XMLList=parentNodes.trainingEventInstance;
// Iterate through each Child Node of the XML
for each(var individualChild:XML in childNodes){
// Return title of the parent
return [EMAIL PROTECTED];
}
}
}
}
Usage:
if you call getCourseTitle(4) you'll get "Miter Saw Safety" and so on...
hope that helps,

I'm trying to write a function to return the title of a course when passed the "KeyID" of a specific course instance, and am running into all sorts of problems (it ain't working being the worst of them).
