Question

我正在尝试显示不同部门的营业时间，我有一个模板，用于多个HoursofOperation元素的单个HoursofOperation元素，它没有给出预期的结果。代码在下面

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

    <xsl:key name="similarDays"

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：周一，周二，周三，周四，周五：上午30点 - 下午7点，上午10点 - 下午6:00，上午11:00 - 下午6:00

模板适用于Sales HoursOfOperation元素，但是对于服务它没有按预期工作。我不明白这个select语句正在做什么<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

Answer 1

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

是“Muenchian分组”方法的一个实例，这是一种基于它们共有的一些值将元素组合在一起的方法。此特定表达式将选择当前上下文元素的所有DaysOfWeek子元素，这些元素是在整个文档中首次提及其开始和结束时间的特定组合。

如果您想使用Muenchian分组但是将其限制为在文档的特定部分内进行分组，那么您需要包含一些唯一标识该部分作为键值的一部分的内容（以便第一个元素具有开始时间1和A部分中的结束时间2与第一个元素具有不同的键值，具有相同的开始和结束时间但在B）部分内。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，不是<xsl:if>块复制“来自销售”和“来自服务”的整套逻辑，你可以在同一个块中处理它们，从HoursTypeCode获取部分名称：

    <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. -->
