我一直在尝试通过Apache FOP将我的XML文档转换为PDF， 但是输出pdf是空白的。
非常感谢任何有关为何发生这种情况的帮助。
代码似乎没有错误地执行：

您仍然获得空白PDF的主要原因是您的其他模板永远不会被应用。我对样式表做了一些更改（例如添加标识转换，更改select，删除不必要的模板并修复Document_Number的拼写）并且我得到了输出PDF。
XSL的修改版本：
<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format">

我还编写了一个快速样式表，用于创建“常规”部分和“运送”部分（基于最初在问题中的HTML输出）。它使用了稍微不同的方法。
