Hi Steve,
  As Mike pointed out, this problem is best solved using Muenchian
grouping method, if you are using XSLT 1.0.

Here is a XSLT 1.0 solution based on Muenchian method:

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

<xsl:output method="html" indent="yes" />

<xsl:key name="by-country" match="entry" use="country" />

<xsl:template match="/report">
  <html>
    <head>
      <title/>
    </head>
    <body>
      <table border="1">
        <xsl:for-each select="//entry[generate-id() =
generate-id(key('by-country', country)[1])]">
          <tr>
            <td><xsl:value-of select="country" /></td>
          </tr>
          <tr>
            <td>Group</td>
            <td>Name</td>
            <td>id</td>
          </tr>
          <xsl:for-each select="key('by-country', country)">
            <tr>
              <td><xsl:value-of select="../@type" /></td>
              <td><xsl:value-of select="name" /></td>
              <td><xsl:value-of select="id" /></td>
            </tr>
          </xsl:for-each>
        </xsl:for-each>
      </table>
    </body>
  </html>
</xsl:template>

</xsl:stylesheet>

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]/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?
