一段时间以来，我一直在使用 RenderX XEP 中的 XSL-FO 制作简单的 PDF，但我对 XPath 涉及的更多功能相对较新。
我有一些看起来像这样的 XML：
<?xml version="1.0" encoding="UTF-8"?>
<report>
<ticket>
<size>A</size>
<department>Dept 1</department>
<category>Cat 1</category>
<product>Product 1</product>
</ticket>
<ticket>
<size>A</size>
<department>Dept 1</department>
<category>Cat 2</category>
<product>Product 2</product>
</ticket>
<ticket>
<size>B</size>
<department>Dept 1</department>
<category>Cat 2</category>
<product>Product 3</product>
</ticket>
<ticket>
<size>B</size>
<department>Dept 1</department>
<category>Cat 1</category>
<product>Product 1</product>
</ticket>
<ticket>
<size>C</size>
<department>Dept 1</department>
<category>Cat 2</category>
<product>Product 2</product>
</ticket>
<ticket>
<size>D</size>
<department>Dept 3</department>
<category>Cat 1</category>
<product>Product 4</product>
</ticket>
<ticket>
<size>D</size>
<department>Dept 1</department>
<category>Cat 1</category>
<product>Product 1</product>
</ticket>
</report>
我需要能够使用 XSLT1.0 格式化对象将这些数据排序到 PDF 中。所需的格式如下：
所有相同大小的票都在单独的表格中（在页面上按字母顺序排序），每个表格都列出了他们的产品，包含在他们的相关类别和部门中。例子：
我曾尝试实施 Muenchian 分组，但在使用大型 XML 提取时，错误的类别属于部门，我无法在每个类别下列出相关产品。
我可能相当凌乱的 XSL：
