This is a classic grouping problem which is best tackled using
xsl:for-each-group in XSLT 2.0, or Muenchian grouping (see
http://www.jenitennison.com/xslt/grouping) in 1.0. The 2.0 solution is:
<xsl:for-each-group select="//entry" group-adjacent="country">
<h2><xsl:value-of select="current-grouping-key()"/></h2>
<table>
<thead>...</thead>
<tbody>
<xsl:for-each select="current-group()">
<tr>
<td><xsl:value-of select="../@type"/></td>
<td><xsl:value-of select="name"/></td>
<td><xsl:value-of select="id"/></td>

Hi Spencer and Mike
Sorry for not giving you the details of my output. Im
looking to display the title for every new country.
So, the html output will look like this:
USA
Group Name id
AAA Adel 12345
AAA Barry 12346
AAA Carl 12347
BBB Dave 12345
BBB Ethel 12346
BBB Fred 12347
EUR
Group Name id
CCC George 24567
CCC Harold 23458
CCC Jennifer 23459
Hope this helps, thanks again!
Steve

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]/c
ountry"/>
<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?

I have a problem holding on to a param or variable value in xslt.
Setting it Globally or Locally.
How can I hold onto the country value? Compare to the
next value, if
country is diff. then replace the value for that param
with the next
country value?
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.
