Sample to create several .fo files with single XSLT 3.0 stylesheet and then run bat command to use FOP on each .fo file to create .pdf file.
Use e.g. Saxon 12 HE java -jar path-to-saxon-dir\saxon-he-12.2.jar -s:article-30-sample.xml -xsl:create-article-list-and-article-docs.xsl -o:article-list.fo to run the XSLT and create the various .fo files.
Then adapt the path in create-pdfs-from-fo-files.bat to point to your FOP installation and run the create-pdfs-from-fo-files.bat to create the PDFs.
