Answer 1

を歓迎しているので、このについての明確な何かを見つけることができませんでした。

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

    <!-- create an index of book nodes group by category --> 
    <xsl:key name="bookindex" match="book" use="category"/> 

    <xsl:template match="collection"> 
    <collections> 
     <!-- select book nodes which are the first node in their relevant index --> 
     <!-- this basically selects the node which has the same id as the first node 
      returned from the index --> 
     <xsl:apply-templates 
      select="book[generate-id() = 
         generate-id(key('bookindex', category)[1])]" 
      mode="group"/> 
    </collections> 
    </xsl:template> 

    <!-- handle the first node as the group pivot --> 
    <xsl:template match="book" mode="group"> 
    <group> 
     <category><xsl:value-of select="category"/></category> 
     <!-- select all book nodes which have the same category as myself --> 
     <xsl:apply-templates select="../book[category=current()/category]"/> 
    </group> 
    </xsl:template> 

    <!-- now handle each node in the book list --> 
    <xsl:template match="book"> 
      <title><xsl:value-of select="title"/></title> 
    </xsl:template> 

</xsl:stylesheet> 

Answer 2

これは "Muenchian grouping" と呼ばれている：

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> 
<xsl:output omit-xml-declaration="yes" indent="yes"/> 
<xsl:strip-space elements="*"/> 
<xsl:key name="kBooksByCat" match="book" use="category"/> 

<xsl:template match="node()|@*"> 
    <xsl:copy> 
    <xsl:apply-templates select="node()|@*"/> 
    </xsl:copy> 
</xsl:template> 

<xsl:template match= 
"book 
    [generate-id() 
    = 
    generate-id(key('kBooksByCat', category)[1]) 
    ] 
"> 
    <category name="{category}"> 
    <xsl:copy-of select="key('kBooksByCat', category)"/> 
    </category> 
</xsl:template> 
</xsl:stylesheet>
