XSL-FO 页码 2a、2b

Question

在我的 XSL-FO 中：我需要在页脚中显示页码。

我的页面布局通常是：第 1、2、3、4、5 页。
有时第 2 页会被 2a 和 2b 替换，因此流程应该是：1、2a、2b、3、4、5。
第 2a 和 2b 页只是第 2 页的扩展页。第 2 页显示两个 table。第 2a 页是一页上的第一个 table（扩展），第 2b 页是另一页上的第二个 table（扩展）。

我需要：
当两个 table 应该在不同的页面上时，将这些页码显示为 2a 和 2b，否则当两个 table 应该在一页上时，显示第 2 页。

为此我需要额外的 <fo:simple-page-master> 和 <fo:conditional-page-master-reference> 吗？如果是这样，我不确定如何组织它，也不知道如何获得显示为 2a 和 2b 的页码。我知道您可以将其用于字母：<fo:page-number format="a"/>.

这个 XML 标志决定了应该打印什么。如果此处为“1”，则应打印第 2a 和 2b 页，如果此处为“0”，则应打印第 2 页。

<PAGE2FLAG>1</PAGE2FLAG>

感谢您的帮助！

这是我的样式表：

Answer 1

根据 @Jean-François Savard 的建议，我已将 <fo:retrieve-marker> 和 <fo:marker> 添加到我的代码中。

请注意，在生成的 FO 文件中，每个 <fo:marker> 必须是 第一个 child 个 <fo:block>，否则您将得到错误 "fo:marker" must be declared before "(%block;)".

我的问题已经解决：它按照我想要的方式工作，页面 2 或页面 2a 和 2b 正确显示。
