XSL-FO 分组标题与节 [英] XSL-FO Grouping title with Section

问题描述

您好，我想将我的 xml 转换为对我的标题进行分组

Hello I want to transform my xml to grouping my titles

这是我的 xml 文件:

here is my xml file:

<?xml version="1.0" encoding="UTF-8"?>
<root>
    <header1>
        <title>Head 1</title>
        <sub>
            <title>sub 1</title>
        </sub>
        <sub>
            <title>sub 2</title>
        </sub>

    </header1>
</root>

这是我的 xslt 文件:

here is my xslt file:

  <xsl:template match="header1">     
        <fo:block>      
            <xsl:number level="multiple" count="header" format="1"/>  
            <xsl:value-of select="./title/text()"/>  
            <xsl:apply-templates/>
        </fo:block>
    </xsl:template>

    <xsl:template match="sub">
        <fo:block>      
            <xsl:number level="multiple" count="sub" format="1.1"/>  
            <xsl:value-of select="./title/text()"/>      
        </fo:block>
    </xsl:template>

预期输出为:

1 Head 
1.1 Head - sub 1
1.2 Head - sub 2

现在的输出:

  Head1 Head 1
  1sub 1
  2sub 2

推荐答案

首先，您的标题元素称为 header1，而不是 header.计算 header 元素总是会产生意想不到的结果.

First of all, your header element is called header1, not header. Counting header elements will always give unexpected results.

对于xsl:number要在多个级别进行计数，您需要指定应该计数的元素，用|分隔它们.下面是生成格式良好的 XSL-FO 文档的完整示例.

For xsl:number to count on multiple levels, you need to specify the elements that should be counted, separating them with |. Below is a full example that generates a well-formed XSL-FO document.

在您当前的输出中，文本过多.这是因为您需要使用空模板覆盖文本节点的内置模板，匹配 text().

In your current output, there is too much text. That's because of the built-in template for text nodes that you need to override with an empty template, matching text().
