xml - 如何停止计算空白页 XSLT/XSLFO

Question

我有一个从第 1 页开始并继续的布局。现在的问题是它也计算空白页。有没有办法强制停止空白页计数。

当前输出:

第 1 页(非空白)- 第 1 页，共 6 页

第2页(空白)

第 3 页(非空白)- 第 3 页，共 6 页

第 4 页(空白)

第 5 页(非空白)- 第 5 页，共 6 页

第6页(空白)

预期输出:

第 1 页(非空白)- 第 1 页，共 3 页

第2页(空白)

第 3 页(非空白)- 第 2 页，共 3 页

第 4 页(空白)

第 5 页(非空白)- 第 3 页，共 3 页

第6页(空白)

上面的输出是(假设有两个页面要显示)

第一页(非空白)第 1 页，共 3 页

第二页(空白)

第三页(非空白)第 3 页，共 3 页

</section>

在上面

<template-edition channel="2" template="">
<edition-content>
    <sectionmap section="Body" region="Body" />
    <sectionmap section="Footer" region="Footer" />
    <sectionmap section="Header" region="address" />
</edition-content>

例子:'Header' 映射到 XSL 区域 'address'(其他相同)

Answer 1

如果您的所有页面都来自一个fo:page-sequence，则没有直接方法可以实现您想要的输出。

在XSL recommendation fo:page-number 的值被定义为页面的 folio-number 特征，它是根据以下规则计算的:

1. The value of the folio-number trait on the first page returned by the fo:page-sequence is constrained to equal the value of the initial-page-number trait.
2. The value of the folio-number trait on subsequent pages is constrained to be one greater than the value on the immediately preceding page.

换句话说，您可以决定从 page-sequence 派生的第一页的初始编号，但是连续的页面获得连续的页码(无论它们是是否显示在页面中)。

这是一般的答案；在您的特定情况下，可能有间接方法来获得您想要的:

• 可以将您的内容分成不同的 page-sequence，这样每个页面都会生成一个完整页面和一个空白页面(设置 force-page-count="even" 并在第二个 page-sequence 上使用 initial-page-number="2"，依此类推 ...)

• 通过两步方法，您可以使用 FOP 的 intermediate format feature到

  1. 创建没有空白页并带有所需页码的输出
  2. 在编号之间插入空白页
