XSL-FO - 如何生成目录？

Question

我有以下文档结构，我想生成一个适合我的XSLT转换的目录。我尝试了很多东西，但都没有为我工作。有人能帮助我吗？

随着下面的转换，我得到这个警告和空的页码在这个地方。

WARNING: Page 2: Unresolved id reference "N65898" found.

Answer 1

当你输出<chapter>这将只有当你输出ID工作。 <fo:page-number-citation>中的@ref-id需要指向某些东西。

编辑 - 生成的ID

的实施例下面是一个例子的样式表。它将根据输入XML生成一个带有工作TOC的PDF。我使用Saxon 6.5.5和FOP进行了测试。
