I need to process the top n values in a list where n is dynamic. So if n=3 and I had the following XML:
<root> <item>1</item> <item>5</item> <item>3</item> <item>2</item> <item>6</item> <item>4</item> </root>
I need to process <item>'s with values 6,5,4. If I had captured n in a variable/parameter, what is the most efficient way to do this? What I want to avoid is walking the <item> nodset multiple times as there are a lot of <item>s (thousands). Thanks.
