Crap...
My bad, I sent a code sample that didn't have the function calls I was
getting from the XML.
Your sample is exactly what I was looking for.
I never included the functions that the array contains because I
figured that was assumed.
They are just two functions right now that look like this...
private function playNextSection(e:MouseEvent):void{
//
var val:Number = stepArray[stepCount].pv;
var functionCall:String = stepArray[stepCount]["fnct"];
this[functionCall](val);
textwindow.captionTxt.text = stepArray[stepCount].txt;
stepCount++
}
private function testFunction(num:Number):void{
trace("you called testFunction, num --> "+num);
}
private function testFunctionOne(num:Number):void{
trace("you called testFunctionOne, num --> "+num);
}
Everything is working the way I wanted.
Thanks,

Mike asks an important question, but assuming for the moment the
function is
in the same class as playNextSection():
What you're retrieving from the XML is a String. So the line
stepArray[stepCount]["fnct"](val);
isn't going to call a function. It's going to try to treat a string
as a
function... and the main way to do that is via [ ] notation.
I think it's most readable to separate it into two steps:
var functionName:String = stepArray[stepCount]["fnct"];
this[functionName](val); // assuming it's in this class. You may
also have
to cast this[functionName] this as a function; can't test right now

You cant store a function in XML, on the name. You can then use
that name
to construct a call to the function. Where is the function?

Mike,
Neither of these options are working.

Here's what my XML looks like:
<steps>
<step>
<text>NEW TEXT.</text>
<funct>testFunction</funct>
<pausev>1.5</pausev>
</step>
<step>
<text>NEXT TEXT to display .</text>
<funct>testFunctionOne</funct>
<pausev>2.5</pausev>
</step>
</steps>
I have a button that is named mentorNext with this event listener..
mentorNxt.addEventListener(MouseEvent.CLICK,playNextSection);
the function "playNextSection" looks like this...
private function playNextSection(e:MouseEvent):void{
//
var val:Number = stepArray[stepCount].pv;
//stepArray[stepCount].fnct(val);
stepArray[stepCount]["fnct"](val);
textwindow.captionTxt.text =
stepArray[stepCount].txt;
stepCount++
}
If I remove the line for the stepArray function the
textwindow.captionText line works.
The data is there the array is populated properly but I can't get
the
function to act like a function.
I get this error message:
TypeError: Error #1006: value is not a function.
at MainIntro/::playNextSection()

if fnct is a function:
stepArray[0].fnct();
if it is a string:
stepArray[0]["fnct"]();
The 0 is the index from the array you want to retrieve.

I have an array built from and XML file that I want to step through
and one of the nodes will have
a function to call. I thought I did this in AS2 before but can't
find
my code.
I'm stuffing my array with the function string cast as an object
but I
can't seem to find any hints on
how I should be calling that function.
My array is built like this...
[code]
//this works fine
for each (var step:XML in xmlData..step) {
var step_text:String = step.text;
var stepFunc:String = step.funct;
var stepPause:Number = step.pausev;
stepArray.push({txt:step_text,fnct:stepFunc,pv:stepPause});
}
[/code]
I want to call the stepArray.fnct but can't seem to get it to work
nor
can I find an example of how I should go about this.
Any help or link would be greatly appreciated.
