我正在尝试显示不同部门的 HoursofOperation，我有一个模板适用于单个 HoursofOperation 元素，但它没有给出预期的结果。代码如下

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="utf-8" indent="yes"/>

    <xsl:key name="similarDays" 
             match="DaysOfWeek" 
             use="concat(AvailabilityStartTimeMeasure, '|', AvailabilityEndTimeMeasure)" />

    <xsl:template match="/">

        <xsl:for-each select="dealers/HoursOfOperation">
            <xsl:if test="HoursTypeCode ='Service'">
                From service:

                        <xsl:for-each select="key('similarDays', concat(AvailabilityStartTimeMeasure, '|', AvailabilityEndTimeMeasure))">

输出：-

服务时间：周一、周二、周三、周四、周五、周六、周日、周日7:00 - 6:00 销售时间：周一、周二、周三、周四、周五8:30am - 7:00pm周六10:00am - 6:00pm周日11:00am - 下午 6:00

模板对于 Sales HoursOfOperation 元素工作正常，但对于服务它没有按预期工作。我不明白这个 select 语句到底在做什么<xsl:for-each select="DaysOfWeek[count(. | key('similarDays', concat(AvailabilityStartTimeMeasure, '|', AvailabilityEndTimeMeasure))[1]) = 1]">

期望的输出：-

From service:Mon - Sun 7:00am - 6:00pm
From Sales:Mon - Fri 8:30am - 7:00pm
Sat 10:00am - 6:00pm
Sun 11:00am - 6:00pm

DaysOfWeek[count(. | key('similarDays', concat(AvailabilityStartTimeMeasure, '|', AvailabilityEndTimeMeasure))[1]) = 1]

是“Muenchian 分组”方法的一个实例，一种基于元素具有的某些共同值将元素组合在一起的方法。这个特定的表达式将选择DaysOfWeek当前上下文元素的所有子元素，它们是在整个文档中第一次提到它们的开始和结束时间的特定组合。

如果您想使用 Muenchian 分组但将其限制为在文档的特定部分内进行分组，那么您需要包含唯一标识该部分的内容作为键值的一部分（以便第一个元素具有开始时间 1 和结束时间 2在 A 部分内的键值与具有相同开始和结束时间但在 B 部分内的第一个元素具有不同的键值。对于您的情况，合适的唯一标识符可能是HoursTypeCode：

<xsl:key name="similarDays" 
         match="DaysOfWeek" 
         use="concat(../HoursTypeCode, '|',
                     AvailabilityStartTimeMeasure, '|',
                     AvailabilityEndTimeMeasure)" />

分组表达式需要包含相同的唯一标识符

<xsl:if test="HoursTypeCode ='Service'">
  From service:
  <xsl:for-each select="DaysOfWeek[count(. |
      key('similarDays', concat('Service|', AvailabilityStartTimeMeasure, '|', AvailabilityEndTimeMeasure))[1]) = 1]">

     <xsl:for-each select="key('similarDays', concat('Service|', AvailabilityStartTimeMeasure, '|', AvailabilityEndTimeMeasure))">

当然，除了<xsl:if>复制“来自销售”和“来自服务”的整个逻辑集的块之外，您可以在同一个块中处理它们，并从以下部分获取部分名称HoursTypeCode：

    <xsl:for-each select="dealers/HoursOfOperation">
      From <xsl:value-of select="HoursTypeCode"/>:
      <xsl:for-each select="DaysOfWeek[count(. |
          key('similarDays', concat(current()/HoursTypeCode, '|', AvailabilityStartTimeMeasure, '|', AvailabilityEndTimeMeasure))[1]) = 1]">
        <!-- etc. -->
