Tricky XML AS3 question

At least tricky for me, perhaps one of you guru’s will know the answer.

What I want to do in a nutshell: display the last node of an xml file first.

I am using AS3 to pull a dynamically created XML list based on date ranges and display 9 entries. The xml list that I am pulling is dynamically generated by an external vendor and I can not control it or format it. The XML feed contains several nodes with the most recent “entry” placed last in the node list. I need to display the last node first, essentially re-ordering the list from last to first.

Any ideas?

Thanks
