If you need an XSLT 1.0 solution then here is one using Muenchian grouping:

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

   <xsl:output method="text"/>

   <xsl:key name="by-genre" match="book" use="genre"/>

   <xsl:template match="/">
     <xsl:for-each select="catalog/book[generate-id() = 
generate-id(key('by-genre', genre)[1])]">
       <xsl:sort select="count(key('by-genre', genre))" 
data-type="number" order="descending"/>
       <xsl:value-of select="concat(genre, ' - ', count(key('by-genre', 
genre)), '&#13;&#10;')"/>
     </xsl:for-each>
   </xsl:template>

</xsl:stylesheet>
