Answer 1

If you're using Windows:

Download the zip file Saxon-HE 9.9 for Java from http://saxon.sourceforge.net/#F9.9HE and unzip the file to C:\saxon

Use this Python code:

import os
import subprocess

def file_path(relative_path):
    folder = os.path.dirname(os.path.abspath(__file__))
    path_parts = relative_path.split("/")
    new_path = os.path.join(folder, *path_parts)
    return new_path

def transform(xml_file, xsl_file, output_file):
    """all args take relative paths from Python script"""
    input = file_path(xml_file)
    output = file_path(output_file)
    xslt = file_path(xsl_file)

    subprocess.call(f"java -cp C:\saxon\saxon9he.jar net.sf.saxon.Transform -t -s:{input} -xsl:{xslt} -o:{output}")
