It would be helpful if you would provide your expected output.  I.e. What is
your definition of a local maximum for a given node, and provide an
example...

Here is some XSL that you may find helpful.  It removes the maxium and its
two closest sibling nodes (i.e. before and after) of the original list.
Hopefully, you can modify this to suit your needs.  Note that I believe this
requires xslt version 1.1 or higher.

        <x:variable name="nodes">
            <x:for-each select="//PoketTourList/Country/Range">
                <x:sort data-type="number" order="descending"
select="./@Cnt"/>
                <x:if test="position() = 1">
                    <x:variable name="cnt" select="@Cnt"/>
                    <x:variable name="thisNode"
select="//PoketTourList/Country/Range[@Cnt = $cnt]"/>
                    <x:variable name="lastNode"
select="$thisNode/preceding-sibling::*[1]"/>
                    <x:variable name="nextNode"
select="$thisNode/following-sibling::*[1]"/>
                    <x:copy-of select="$lastNode"/>
                    <x:copy-of select="$thisNode"/>
                    <x:copy-of select="$nextNode"/>
                </x:if>
            </x:for-each>
        </x:variable>

        <x:variable name="excludedNodes">
            <x:for-each select="//PoketTourList/Country/Range">
                <x:variable name="currentNode" select="."/>
                  <x:choose>
                      <x:when test="$currentNode/@Cnt = $nodes//@Cnt"><!--
do nothing --></x:when>
                      <x:otherwise><x:copy-of

                  </x:choose>
            </x:for-each>
