如何使用“insref”和“pref”对下面的元素进行分组我曾尝试在 xslt 版本 1 中使用生成密钥 ID。

XML：

<?xml version="1.0" encoding="ISO-8859-1"?>
<!-- Edited by XMLSpy® -->
<catalog>
   <mylist>
    <cd id="1" insref="#10">
        <title>Empire Burlesque</title>
        <artist>Bob Dylan</artist>
        <country>USA</country>
        <company>Columbia</company>
        <price>10.90</price>
        <year>1985</year>
    </cd>
    <cd id ="2" insref="#20" pref="#1">
        <title>Hide your heart</title>

    <cd id="4" insref="#56" pref="#1">

    <cd id="7" insref="#56" pref="#2">

        <price>10.80</price>
        <year>1996</year>
    </cd>

期望的结果：

TITLE               ARTIST          ID  INSREF  PREF    Qty
Empire Burlesque    Bob Dylan       1   10      
Hide your heart     Bonnie Tyler    2   20      1       1   
Lonly heart         Bonnie Tyler    3   520     1       1       
Still got the blues Gary Moore      4   56      1       1   
Still got the blues Gary Moore      4   56      2       3   
Maggie May          Rod Stewart     8   78      2       1   
Romanza             Andrea Bocelli  9   45      1       1
Romanza             Andrea Bocelli  10  45      2       1

这就是我所拥有的。我也在使用密钥生成功能。知道这个 xslt 有什么问题。至于计数，我正在考虑获得唯一键计数。

<xsl:key name="by-accessRefs" match="cd" use="concat(@insref,@pref)"/>

<xsl:template match="/">

    <h2>My CD Collection</h2>
    <table border="1">
      <tr bgcolor="#9acd32">

      <xsl:for-each select="catalog/mylist/cd[generate-id(.) = generate-id(key('by-accessRefs',concat(@insref,@pref)[1])]">

这个 XSLT 1.0 转换：

<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="kCDByProps" match="cd" use=
  "concat(title,'+',artist,'+',@insref,'+',@pref)"/>

 <xsl:template match="/*">
     <table>
       <thead>
         <tr>
           <td>TITLE</td><td>ARTIST</td><td>ID</td><td>INSREF</td><td>PREF</td><td>Qty</td>
         </tr>
       </thead>
       <xsl:apply-templates select=
        "mylist/cd
            [generate-id()
            =
             generate-id(key('kCDByProps', 
                               concat(title,'+',artist,'+',@insref,'+',@pref)
                              )[1])
            ]
        "/>
     </table>
 </xsl:template>

 <xsl:template match="cd">
  <xsl:variable name="vGroup" select=
    "key('kCDByProps', concat(title,'+',artist,'+',@insref,'+',@pref))"/>

  <tr>

应用于提供的 XML 文档时：

产生以下 HTML 输出：

我假设您需要的输出是一个 HTML 表：

样式表文件

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:xs="http://www.w3.org/2001/XMLSchema"

    exclude-result-prefixes="xs xd"
    version="2.0">

    <xsl:output method="html" indent="yes"/>

    <xsl:key name="kTitle" match="title" use="text()"/>

    <xsl:template match="/">
        <table>
            <thead>
                <tr>
                    <th>TITLE</th>
                    <th>ARTIST</th>
                    <th>ID</th>
                    <th>INSREF</th>
                    <th>PREF</th>
                    <th>Qty</th>
                </tr>
            </thead>
            <tbody>
                <xsl:for-each-group select="//cd" group-by="@id">
                    <tr>
                        <td><xsl:value-of select="title"/></td>
                        <td><xsl:value-of select="artist"/></td>
                        <td><xsl:value-of select="@id"/></td>
                        <td><xsl:value-of select="substring-after(@insref,'#')"/></td>
                        <td><xsl:value-of select="substring-after(@pref,'#')"/></td>
                        <td><xsl:value-of select="count(key('kTitle',title/text()))"/></td>
                    </tr>
