xml - 如何在 'listBulleted' 元素出现时

问题描述

元素 'listBulleted' 具有相同的父级，在这里我们试图只对那些具有连续/计数的 'listBulleted' 元素进行混合，否则保持原样：

注意：我们正在创建特定的 '<xsl:template match="listBulleted">' 模板，以便我们可以轻松地移动/添加到其他 xslt。

输入 XML： 在此处输入图像描述

<?xml version="1.0" encoding="UTF-8"?>
<root>
<listBulleted>
    <listItem><para flow="new"><emphasis bold="yes">Design.</emphasis> Approval of the specific design of the tiebacks or underpinning.</para>

XSLT 代码：

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

<xsl:template match="listBulleted">

        <xsl:apply-templates/>
        <xsl:if test="following-sibling::node()[1][self::listBulleted]">

        </xsl:if>
    </listBulleted>
</xsl:template>
<xsl:template match="listBulleted[preceding-sibling::node()[1][self::listBulleted]]"/>

</xsl:stylesheet>

解决方案

教科书的方法是group-adjacent：

<xsl:template match="*[listBulleted]">
    <xsl:copy>
        <xsl:for-each-group select="*" group-adjacent=". instance of element(listBulleted)">
            <xsl:choose>
                <xsl:when test="current-grouping-key()">
                    <xsl:copy>
                        <xsl:apply-templates select="current-group()/node()"/>
                    </xsl:copy>
                </xsl:when>
                <xsl:otherwise>
                    <xsl:apply-templates select="current-group()"/>
                </xsl:otherwise>
            </xsl:choose>
        </xsl:for-each-group>
    </xsl:copy>
</xsl:template>

但是，它与 on 不匹配listBulleted，因为它不是您需要分组的容器。
