XSLT 1.0 分组依据 [英] XSLT 1.0 Group By

问题描述

我有以下 XML 数据:

I have the following XML data:

<?xml version="1.0" encoding="iso-8859-1"?>
<results>
    <result>
        <MemberFirstName>JOHN</MemberFirstName>
        <MemberLastName>DOE</MemberLastName>
        <MemberLogin>1</MemberLogin>
        <Store>0180</Store>
    </result>
    <result>
        <MemberFirstName>JANE</MemberFirstName>
        <MemberLastName>DOE</MemberLastName>
        <MemberLogin>2</MemberLogin>
        <Store>0180</Store>
    </result>
    <result>
        <MemberFirstName>ALAN</MemberFirstName>
        <MemberLastName>SMITH</MemberLastName>
        <MemberLogin>3</MemberLogin>
        <Store>0181</Store>
    </result>
    <result>
        <MemberFirstName>DAVID</MemberFirstName>
        <MemberLastName>GREEN</MemberLastName>
        <MemberLogin>4</MemberLogin>
        <Store>0183</Store>
    </result>
</results>

在 XSLT 1.0 中，我想为每个商店的员工分组并创建一个表.所以在上面的数据中，将创建 3 个表.前 2 条记录(存储 180)等有两行的表.

In XSLT 1.0, I want to group by and create a table for employees in each store. so in the above data, 3 tables would be created. A table with two rows for the first 2 records (store 180), etc..

如何在 XSLT 1.0 中执行此操作?

How can I do this in XSLT 1.0?

<table id="table">
  <tr class="heading">
    <th scope="col">Member Id</th>
    <th scope="col">First Name</th>
    <th scope="col">Last Name</th>
  </tr>
  <xsl:for-each select="results/result">
    <tr>
      <td><xsl:value-of select="MemberLogin"/></td>
      <td><xsl:value-of select="MemberFirstName"/></td>
      <td><xsl:value-of select="MemberLastName"/></td>
    </tr>
  </xsl:for-each>
</table>

推荐答案

Muenchian grouping 是最佳方法；类似:

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl">

  <xsl:output method="xml" indent="yes"/>      
  <xsl:key name="groups" match="/results/result" use="Store" />

  <xsl:template match="/results">
    <xsl:apply-templates select="result[generate-id() = generate-id(key('groups', Store)[1])]"/>
  </xsl:template>
  <xsl:template match="result">
    <h1><xsl:value-of select="Store"/></h1>
    <table id="{Store}">
      <tr class="heading">
        <th scope="col">Member Id</th>
        <th scope="col">First Name</th>
        <th scope="col">Last Name</th>
      </tr>
      <xsl:for-each select="key('groups', Store)">
        <tr>
          <td><xsl:value-of select="MemberLogin"/></td>
          <td><xsl:value-of select="MemberFirstName"/></td>
          <td><xsl:value-of select="MemberLastName"/></td>
        </tr>
      </xsl:for-each>
    </table>
  </xsl:template>
</xsl:stylesheet>
