XSL объединяет несколько полей в новое поле в порядке

Question

Я хотел бы создать новые элементы. Каждый новый элемент должен содержать ключ записи, первый элемент кода и первое вхождение элемента Code_Text. Процесс будет повторяться для каждого из элементов Code и Code_Text, поскольку теоретически их должно быть одинаковое количество. Тот же XSL также будет применен к парам значений Opinion / Opinion_Text и Reason / Reason_Text.

Я использую предыдущее решение 1.0 из предыдущего вопроса, но не уверен, как его изменить. При тестировании у меня есть доступ только к версии 1.0. 2.0 доступен только на сервере. Мне нравится 2.0, поскольку это легче понять, но любой из них будет работать. В Java я бы просто l oop просматривал элементы, строил массив или список и затем выводил, когда закончил. Не уверен, как это сделать в XSL. Кроме того, в моем файле гораздо больше элементов, чем показано, и я предпочитаю обобщенное решение c, которое можно адаптировать к разным макетам XML файла. По сути, я хотел бы скопировать все, а затем l oop через пары значений, соединенные с ключом записи, выводя каждый в новый элемент с тем же именем. Я читал, что использование не является оптимальным решением, но не понимаю, почему в моем случае использования. Есть ли способ l oop просматривать данные, накапливать нужные значения и затем передавать их в выходной шаблон или это неверный путь к решению?

Если вы можете использовать xsl-2.0, вы можете использовать функцию xsl:for-each-group, используя group-adjacent

Мы сгруппируем узлы, заканчивающиеся на _Text. Используйте этот шаблон (см. Пояснения в комментариях):

<xsl:template match="Record">
    <xsl:variable name="key" select="Key"/>
    <xsl:copy>
        <xsl:for-each-group select="*" group-adjacent="boolean(self::*[ends-with(local-name(), '_Text')])">
        <!-- test if a node ends with '_Text', boolean will return either true or false -->
            <xsl:choose>
                <!-- when true -->
                <xsl:when test="current-grouping-key()">
                    <!-- copies the current group  -->
                    <xsl:copy-of select="current-group()"/>
                    <!-- process each node of the current group  -->
                    <xsl:for-each select="current-group()">
                        <xsl:variable name="new_name" select="concat(
                            substring-before(current-group()[1]/local-name(), '_'),
                            '_Combined')"/>
                        <xsl:element name="{$new_name}">
                            <xsl:value-of select="concat($key, '|', substring-before(., ' '), '|', .)"/>
                        </xsl:element>
                    </xsl:for-each>
                </xsl:when>
                <xsl:otherwise>
                    <xsl:apply-templates select="current-group()"/>
                </xsl:otherwise>
            </xsl:choose>
        </xsl:for-each-group>
    </xsl:copy>
</xsl:template>
