<xsl:variable name="big-string">
  <xsl:for-each select="Sample/*">
    <xsl:if ". != ''">
      <xsl:value-of select="."/>
      <xsl:if "position() != last()">,</xsl:if>
    </xsl:if>
  </xsl:for-each>
</xsl:variable>

Note that if the last child node is empty you'll still get a trailing comma
in your string--I'm sure there's a way to fix that but I have a meeting to
go to . . .  ;-)
