Best way to "page" through data?

Question

If I have a XM, something like
<people>
<person>
<firstname>john</firstname>
<lastname>smith</lastname>
</person>
<person>
<firstname>robert</firstname>
<lastname>walker</lastname>
</person>
</people>
And I create some bound fields to display this, what's the best way to "page" the data?
I know I can create an XML variable of the data and then access person[0].firstname, but I need to have a button or other ui element that would choose person 0,1,2,3 etc.
Normally I's use a list, but this application calls for a static screen where only the data changes when buttons are chosen.

Answer 1

I use this method(this is simplified) as it doesn't require any sort of data services, you can have change events etc for editing/deleteing. the slider is just for poc, a prev/next button could just as easily do.
