Нужна помощь в условно-применении шаблона с сортировкой в ​​XSLT

Я пытаюсь получить первую строку, которая соответствует критериям и отсортирована по des c в wd: Completed_DateTime. Там может быть несколько строк, которые соответствуют критериям. Например, wd: Instance_Set_Reference / wd: ID [@wd: type = 'Customer_Category_ID' и text () = 'CRDRG'] ниже XML вернет две строки, но я хочу, чтобы первое значение wd: Instance_Set_Reference / wd: ID [@wd: type = 'Customer_Category_ID' и text () = 'CRDRG'] отсортировано по des c на wd: Completed_DateTime.

Sample XML - 

<?xml version='1.0' encoding='UTF-8'?>
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:wd="urn:com.workday/bsvc">
    <env:Body>

Sample XSLT - 

    <?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="3.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:wd="urn:com.workday/bsvc" exclude-result-prefixes="xs env wd">
    <xsl:output method="xml" indent="yes" omit-xml-declaration="yes"/>
    <xsl:template match="/">
        <xsl:for-each select="/env:Envelope/env:Body/wd:Get_Integration_Events_Response/wd:Response_Data/wd:Integration_Event/wd:Integration_Event_Data[wd:Integration_Runtime_Parameter_Data/wd:Instance_Set_Reference/wd:ID[@wd:type = 'Customer_Category_ID']/text()= 'CRXXX']">
            <xsl:sort select="wd:Completed_DateTime" order="descending"/>
            <xsl:if test="position()=1">
                <Revenue_Stream>
                    <xsl:value-of select="wd:Integration_Runtime_Parameter_Data/wd:Instance_Set_Reference/wd:ID[@wd:type = 'Customer_Category_ID']/text()"/>
                </Revenue_Stream>
                <Completion_date>
                    <xsl:value-of select="wd:Completed_DateTime"/>
                </Completion_date>
            </xsl:if>
        </xsl:for-each>
    </xsl:template>
</xsl:stylesheet>

Ожидаемый результат - 

<Root>
   <Revenue_Stream>CRXXX</Revenue_Stream>
    <Completion_date>2020-02-10T11:27:33.111-08:00</Completion_date>
</Root>

Мне нужно выбрать это значение из XML, в котором будет много строк. Так что я не уверен, что подход, который я использую, эффективен с точки зрения производительности. Некоторые рекомендации по этому вопросу будут оценены.

Другой подход (сортировка в порядке убывания и получение первого элемента) заключается в выборе максимального значения xs:dateTime с помощью функции max, а затем в выборе (первого) элемента с этой максимальной датой: 

<xsl:template match="/">
    <Root>
        <xsl:variable
          name="max"
          select="let $elements := /env:Envelope/env:Body/wd:Get_Integration_Events_Response/wd:Response_Data/wd:Integration_Event/wd:Integration_Event_Data[wd:Integration_Runtime_Parameter_Data/wd:Instance_Set_Reference/wd:ID[@wd:type = 'Customer_Category_ID'] = 'CRXXX'],
                  $max-dateTime := max($elements/wd:Completed_DateTime/xs:dateTime(.))
                  return head($elements[xs:dateTime(wd:Completed_DateTime) eq $max-dateTime])"/>
        <Revenue_Stream>
            <xsl:value-of select="$max/wd:Integration_Runtime_Parameter_Data/wd:Instance_Set_Reference/wd:ID[@wd:type = 'Customer_Category_ID']"/>
        </Revenue_Stream>
        <Completion_date>
            <xsl:value-of select="$max/wd:Completed_DateTime"/>
        </Completion_date>                
    </Root>
</xsl:template>

Как и в случае с любым другим вопросом, связанным с производительностью, единственный способ узнать это - измерить в вашей среде данные вашего процессора и образец данных.
