selecting first child of XMLList

Question

I have an application in Flex that retrieves XMLList (Tests) from a remote site which suppose to normally contain 5 children (Test) I use for each to loop through the XMLList and do some chartings which works fine. In some weird cases I received up to 10 children in my XMList and my application chose to use the last 5 whereas the correct set suppose to be the first 5 sets. How do i select just the first 5 sets and ignoring the last sets?

Answer 1

I have been able to solve this. I used the unix-time to choose between start time and endtime.
