Filter XML Data for Text Fields.

Question

Hi,
I'm trying to display a single record out of an XML database
into dynamic fields in my MovieClip. I need to be able return a
single record based on the current time. Attached is a sample of my
XML data.
I was wondering if this could be acheived with a DataSet
filterFunction? If it is possible, what code would I need to
include?
Finally, do I need to pass my full DataSet to an array or do
I need to filter first & then pass to an array?
Thankyou.

There's a pattern that almost every wpf dveloper uses and it's called mvvm.
Google it, there'll be a shed load of articles.
It's a passive view pattern in that the view has minimal logic in it.
The view is your window ( or usercontrol).
You can add a listboxitem to the listbox.items collection but i would only do  that if it's a very simple static collection.
You can bind a collection to itemssource and the listbox will create a listboxitem for each things it gets from that collection.
It creates them using a datatemplate.
When you do that binding apparently directly to a collection a collectionvie is automagically created between control and collection.
You can explicitly create one of those collectionview things yourself and this is agreat way to filter and sort.
You can also use one of those collectionviews to navigate the collection setting the current item in the viewmodel.
That can be synced in the view so you select an item from the viewmodel.
I think I probably drifted off topic there somewhat.
Mvvm is probably different from stuff you've done before.
It's easier to do a bunch of things using mvvm plus it's what any prospective employer will want.
Along with tdd/bdd it's industry standard.
Big tip: learn it.
You want to avoid showing a user a huge load of data. Not so much for performance reasons but because users can only cope with so much data at a time.
Hope that helps.
