选择当前元素和当前元素的下一个元素之间的所有元素 [英] Select all of an element between the current element and the next of the current element

问题描述

使用 XSLT 1.0(最好)，如何选择出现在当前元素和下一次当前元素出现之间的所有元素?

Using XSLT 1.0 (preferably), How can I select all of an element which occurs between the current element and the next time the current element occurs?

假设我有这个 XML(已编辑):

Say I have this XML (edited):

<root>
    <heading_1>Section 1</heading_1>
    <para>...</para>
    <list_1>...</list_1>
    <heading_2>Section 1.1</heading_2>
    <para>...</para>
    <heading_3>Section 1.1.1</heading_3>
    <para>...</para>
    <list_1>...</list_1>
    <heading_2>Section 1.2</heading_2>
    <para>...</para>
    <footnote>...</footnote>
    <heading_1>Section 2</heading_1>
    <para>...</para>
    <list_1>...</list_1>
    <heading_2>Section 2.1</heading_2>
    <para>...</para>
    <list_1>...</list_1>
    <list_2>...</list_2>
    <heading_3>Seciton 2.1.1</heading_3>
    <para>...</para>
    <heading_2>Section 2.2</heading_2>
    <para>...</para>
    <footnote>...</footnote>
</root>

处理heading_1 时，我想选择我正在处理的标题和下一个heading_1 之间的所有heading_2.在处理 heading_2 等时选择 heading_3 相同，你会得到图片.

When processing heading_1 I want to select all of heading_2 between the heading I am processing and the next heading_1. The same for selecting heading_3 when processing heading_2 etc. you get the picture.

推荐答案

你可以使用这个:

following-sibling::heading_2[generate-id(preceding-sibling::heading_1[1]) = 
                             generate-id(current())]

工作示例:

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

  <xsl:template match="@* | node()">
    <xsl:copy>
      <xsl:apply-templates select="@* | node()"/>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="/*">
    <xsl:copy>
      <xsl:apply-templates select="heading_1" />
    </xsl:copy>
  </xsl:template>

  <xsl:template match="heading_1">
    <xsl:copy>
      <xsl:apply-templates
        select="following-sibling::heading_2[generate-id(
                                                preceding-sibling::heading_1[1]) = 
                                             generate-id(current())]" />
    </xsl:copy>
  </xsl:template>

  <xsl:template match="heading_2">
    <xsl:copy>
      <xsl:apply-templates
        select="following-sibling::heading_3[generate-id(
                                                preceding-sibling::heading_2[1]) = 
                                             generate-id(current())]" />
    </xsl:copy>
  </xsl:template>    
</xsl:stylesheet>

在您的示例输入上运行时的结果:

Result when run on your sample input:

<root>
  <heading_1>
    <heading_2>
      <heading_3>...</heading_3>
    </heading_2>
    <heading_2 />
  </heading_1>
  <heading_1>
    <heading_2>
      <heading_3>...</heading_3>
    </heading_2>
    <heading_2 />
  </heading_1>
</root>
