XSL-FO - 如何在两个列表块中继续编号？

Question

有人知道如何通过XSL-FO转换实现这一点吗？问题的细节应该从下面的代码中清楚。

Input:

<section> 
    <title>Section 1</title> 
    <orderedlist> 
     <listitem><para>item 1.1</para></listitem> 
     <listitem> 
      <para>item 1.2</para> 
      <orderedlist> 
       <listitem><para>item a</para></listitem> 
       <listitem><para>item b</para></listitem> 
      </orderedlist> 
     </listitem> 
    </orderedlist> 
</section> 
<section> 
    <title>Section 2</title> 
    <orderedlist> 
     <listitem><para>item 2.1</para></listitem> 
     <listitem><para>item 2.2</para></listitem> 
    </orderedlist> 
</section> 

Desired output:

Section 1 
1. item 1.1 
2. item 1.2 
    a. item a 
    b. item b 

Section 2 
3. item 2.1 
4. item 2.2 

Here is the XSL file for lists:

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

    <!-- templates for lists - supports numbered and itemized types --> 
    <!-- the maximum depth is currently 2 --> 
    <xsl:template match="orderedlist"> 
     <fo:list-block start-indent="0.5cm" space-before="0.2cm" 
      provisional-distance-between-starts="0.7cm"> 
      <xsl:apply-templates /> 
     </fo:list-block> 
    </xsl:template> 
    <xsl:template match="orderedlist//orderedlist"> 
     <fo:list-block start-indent="1.2cm" provisional-distance-between-starts="0.7cm" 
      padding-top="-0.2cm" padding-bottom="0.2cm"> 
      <xsl:apply-templates /> 
     </fo:list-block> 
    </xsl:template> 
    <xsl:template match="itemizedlist"> 
     <fo:list-block start-indent="0.5cm" space-before="0.2cm"

      padding-top="-0.2cm" padding-bottom="0.2cm"> 
      <xsl:apply-templates /> 
     </fo:list-block> 
    </xsl:template> 
    <xsl:template match="orderedlist/listitem"> 
     <fo:list-item margin-top="0.1cm"> 
      <fo:list-item-label end-indent="label-end()"> 
       <fo:block> 
        <xsl:number count="listitem" format="1." /> 
       </fo:block> 
      </fo:list-item-label> 
      <fo:list-item-body start-indent="body-start()"> 
       <fo:block> 
        <xsl:apply-templates /> 
       </fo:block>

     </fo:list-item> 
    </xsl:template> 
    <xsl:template match="orderedlist//orderedlist/listitem"> 
     <fo:list-item> 
      <fo:list-item-label end-indent="label-end()"> 
       <fo:block> 
        <xsl:number count="listitem" format="a." /> 
       </fo:block> 
      </fo:list-item-label> 
      <fo:list-item-body start-indent="body-start()"> 
       <fo:block> 
        <xsl:apply-templates /> 
       </fo:block> 
      </fo:list-item-body>

      <fo:list-item-label end-indent="label-end()"> 
       <fo:block>&#8226;</fo:block> 
      </fo:list-item-label> 
      <fo:list-item-body start-indent="body-start()"> 
       <fo:block> 
        <xsl:apply-templates /> 
       </fo:block> 
      </fo:list-item-body> 
     </fo:list-item> 
    </xsl:template> 
    <xsl:template match="itemizedlist//itemizedlist/listitem"> 
     <fo:list-item> 
      <fo:list-item-label end-indent="label-end()"> 
       <fo:block>&#8226;</fo:block> 
      </fo:list-item-label> 
      <fo:list-item-body start-indent="body-start()"> 
       <fo:block> 
        <xsl:apply-templates /> 
       </fo:block> 
      </fo:list-item-body> 
     </fo:list-item> 
    </xsl:template> 
</xsl:stylesheet>

假设你输入样本（加入部分最上面的元件，使良好的形成样品）：

<sections> 
<section> 
    <title>Section 1</title> 
    <orderedlist> 
     <listitem><para>item 1.1</para></listitem> 
     <listitem> 
      <para>item 1.2</para> 
      <orderedlist> 
       <listitem><para>item a</para></listitem> 
       <listitem><para>item b</para></listitem> 
      </orderedlist> 
     </listitem> 
    </orderedlist> 
</section> 
<section> 
    <title>Section 2</title> 
    <orderedlist> 
     <listitem><para>item 2.1</para></listitem> 
     <listitem><para>item 2.2</para></listitem> 
    </orderedlist> 
</section> 
</sections> 

在第一电平的给定的ListItem可以使用：

count(
    preceding-sibling::listitem 
    | 
    ../../preceding-sibling::section/orderedlist/listitem) 
    + 1 

例如：

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

    <xsl:template match="sections"> 
     <fo:block> 
      <xsl:apply-templates select="section"/> 
     </fo:block> 
    </xsl:template> 

    <xsl:template match="section"> 
     <fo:list-block> 
      <xsl:apply-templates select="title | orderedlist/listitem"/> 
     </fo:list-block> 
    </xsl:template> 

    <xsl:template match="title"> 
     <fo:list-item> 
      <xsl:value-of select="."/> 
     </fo:list-item> 
    </xsl:template> 

    <xsl:template match="listitem"> 
     <fo:list-item> 
      <xsl:number 
       value="count(
       preceding-sibling::listitem 
       | 
       ../../preceding-sibling::section/orderedlist/listitem) 
       + 1" format="1.&#x20;"/> 
     </fo:list-item> 
    </xsl:template> 
</xsl:stylesheet> 

产生：

<fo:block xmlns:fo="http://www.w3.org/1999/XSL/Format"> 
    <fo:list-block> 
     <fo:list-item>Section 1</fo:list-item> 
     <fo:list-item>1. </fo:list-item> 
     <fo:list-item>2. </fo:list-item> 
    </fo:list-block> 
    <fo:list-block> 
     <fo:list-item>Section 2</fo:list-item> 
     <fo:list-item>3. </fo:list-item> 
     <fo:list-item>4. </fo:list-item> 
    </fo:list-block> 
</fo:block> 

Answer 2

你有没有使用的DocBook和DocBook-XSL样式特别的原因？这会给你很多“免费”（也许你已经知道了）。

在DocBook中，您要求的内容已经实现。 <orderedlist>上有continuation属性，指示列表中的编号是否从前面的列表继续。这在DocBook-XSL样式表中为FO输出提供了支持（查看fo/lists.xsl和common/common.xsl以了解它是如何完成的）。
