 local extremums

I have a problem with determining local extremums (precisely - local 
maximums) of the list.

I mean I need to realize next algorithm:
1. take the list (it is //PoketTourList/Country/Range on first iteration)
2. determine the maximum @Cnt of this list
3. cast away this maximum and two his nearest neighbours
4. if line isn't empty than goto step 1
So I need a list with any flag showing Range is local extremum or not.
Or I need a way to go throw whole list and determine if each Range is local 
extremum or not on every step.

The list structure is:
<PoketTourList numChild="21">
	<Country ID="12">
		<Range PriceFrom="0" PriceTo="100" Cnt="0"/>
		<Range PriceFrom="100" PriceTo="150" Cnt="0"/>
		<Range PriceFrom="150" PriceTo="200" Cnt="71"/>
		<Range PriceFrom="200" PriceTo="250" Cnt="376"/>
		<Range PriceFrom="250" PriceTo="300" Cnt="751"/>
		<Range PriceFrom="300" PriceTo="350" Cnt="684"/>
		<Range PriceFrom="350" PriceTo="400" Cnt="585"/>
		<Range PriceFrom="400" PriceTo="500" Cnt="1135"/>
		<Range PriceFrom="500" PriceTo="600" Cnt="787"/>
		<Range PriceFrom="600" PriceTo="700" Cnt="586"/>
		<Range PriceFrom="700" PriceTo="800" Cnt="461"/>
		<Range PriceFrom="800" PriceTo="1000" Cnt="485"/>
		<Range PriceFrom="1000" PriceTo="1200" Cnt="173"/>
		<Range PriceFrom="1200" PriceTo="1400" Cnt="86"/>
		<Range PriceFrom="1400" PriceTo="10000" Cnt="91"/>

Please, please, help me!
