Java生成PDF的另一种方法

经常会用iText或者Jasper来生成pdf，今天看到另外一种生成pdf的方法，感觉挺好的。

Philipp Reichart‘s answer:

I prefer outputting my data into XML (using Castor, XStream or JAXB), then transforming it using a XSLT stylesheet into XSL-FO and render that with Apache FOP into PDF. Worked so far for 10-page reports and 400-page manuals. I found this more flexible and stylable than generating PDFs in code using iText.

我又搜索了一下怎么搞XSL-FO，发现了https://www.antennahouse.com/XSLsample/howtoRC/Howtodevelop-en-2a.pdf。文件已经下载了下来。
