有人知道如何通过 XSL-FO 转换来实现这一目标吗？从下面的代码中应该清楚问题的详细信息。

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">

    <!-- 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">

假设您输入的样本是（添加了最顶部的部分元素以使样本格式正确）：

<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>

在给定的第一级列表项中，您可以使用：

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>

您是否有不使用 DocBook 和DocBook-XSL样式表的特殊原因？这会给你很多“免费”（也许你已经知道了）。

在 DocBook 中，您所要求的已经实现。有一个continuation属性<orderedlist>表示列表中的编号是否从前一个列表继续。这在 FO 输出的 DocBook-XSL 样式表中得到支持（查看 fo/lists.xsl 和 common/common.xsl 以了解它是如何完成的）。
