Re: [xsl] XSL hold, compare, and replace param value

Hope this is what you're looking for:

When I run this XSL:

<?xml version='1.0'?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:template match="/">
	<xsl:apply-templates/>
</xsl:template>

<xsl:template match="*">
<xsl:copy>
	<xsl:copy-of select="@*"/>
	<xsl:apply-templates/>
</xsl:copy>
</xsl:template>

<xsl:template match="country[parent::entry/following-sibling::entry]">
<xsl:variable name="nextCountry"
select="parent::entry/following-sibling::entry[1]/country"/>
<xsl:choose>
<xsl:when test="$nextCountry = .">
<country><xsl:apply-templates/></country>
</xsl:when>
<xsl:otherwise>
<country><xsl:value-of select="$nextCountry"/></country>
</xsl:otherwise>
</xsl:choose>
</xsl:template>

<xsl:template match="country[not(parent::entry/following-sibling::entry)]">
<xsl:variable name="nextCountry"
select="ancestor::group/following-sibling::group[1]/entry[1]/country"/>
<xsl:choose>
<xsl:when test="$nextCountry = . or not($nextCountry)">
<country><xsl:apply-templates/></country>
</xsl:when>
<xsl:otherwise>
<country><xsl:value-of select="$nextCountry"/></country>
</xsl:otherwise>
</xsl:choose>
</xsl:template>

</xsl:stylesheet>

Against your XML above, I get Fred's Country Changing as he is the
only one who's next country differs,,, Am I reading you correctly?

Please take a step back. Try to describe the problem: what's the input,
what's the required output?

It looks to me as if you are trying to code a solution using ideas learned
from other programming languages, which might not be the right way to tackle
the problem in XSLT.
