英国必须加下划线或只是红色

Answer 1

您可以按组成员的数量对组进行排序，然后设置最后一个（按升序排列）或第一个按降序排序，以便更改

<xsl:for-each-group select="CATALOG/CD" group-by="COUNTRY">
    <td bgcolor="#32a6cd"><xsl:value-of select="COUNTRY"/></td>

到

<xsl:for-each-group select="CATALOG/CD" group-by="COUNTRY">
  <xsl:sort select="count(current-group())" order="descending"/>
  <td bgcolor="#32a6cd" style="{if (position() eq 1) then 'text-decoration: underline;' else ()}">
    <xsl:value-of select="COUNTRY"/>
  </td>

Answer 2

如果国家/地区必须按行数而不是行数进行排序，则有助于对这些组进行一些预处理并将其存储在变量中：
