Answer 1

如果國家有比行數它有助於做組的一些預處理，並將其存儲在一個變量另一個字段進行排序：

Answer 2

您可以通過小組成員的組數進行排序，然後樣式的最後一個（升序）或降序排列第一，從而改變

<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>
