AS3/ XML Loop through a group of parsed xml paths and update them in the same textfields.

Posted on 2009-07-01

With the following code I have several dynamic textfields that have an unchangeable xml path.  I what to be able to loop to the next node section of the xml and load them into the same textfields upon an update function.  Please look at mu code and see if this makes sense...

As you can see in the code I have several sections being updated, but what I would like to do is simplify this so that no matter how many xml nades are produced they will be updated into the same textfields (upon another function probably going to be a timer).

Also the: Flights.flight_mc.schedTime_txt.text = newTimeStr; paths will need to be updated as well, but they are unique as they have different variables associated with them.  I hope I havent made this too difficult to understand.  If so I would be glad to elaborate...  Just let me knoe what you need to know.

As always any help is greatly appreciated!

Okay here is what I have thus far which is working, sort of...  The problem:  once the first 5 nodes have been loaded, how do I increment through to the next five and so on and so on...  Also along with that how do I increment through my newTimeStr variable?  Hope this makes it a clearer on what I am trying to accomplish...

so to recap:  there are five movieclips each containing 6 dynamic textfields.  Each movieclip will load in the next specified xml node and its corresponding text.  Once I reach the end of those 5 nodes how do I increment it so that on a function such as click to next it loads the next 5 nodes into the same movieclip textfields?

Thanks Again, and any direction is helpful!

well, this looks like a great place to introduce a for loop, and populate the movieclip text fields with it...

and get everything out of the XML event handler... it should be in a seperate function.

also, if you are going to use a sequentially numbered movieclip structure, then don't start with a generic clip name...

so..  "flight_mc"  should actually be "flight_mc1"

change that and make this easier on everyone...   :)
