import aspose.pdf as ap
import xml.etree.ElementTree as ET
from io import BytesIO

def example_xslt_to_pdf():
    data_dir = "C:/tmp/"
    with open("XMLFile1.xml", "r") as xml_file:
        xml_content = xml_file.read()
    with open("XSLTFile1.xslt", "r") as xslt_file:
        xslt_content = xslt_file.read()

    options = ap.HtmlLoadOptions()
    # Set page size to A5
    options.page_info.height = 595
    options.page_info.width = 420

    pdf_document = ap.Document(transform_xml_to_html(xml_content, xslt_content), options)
    pdf_document.save(data_dir + "data_xml.pdf")

def transform_xml_to_html(input_xml, xslt_string):
    transform = ET.XSLT(ET.XML(xslt_string))
    xml_tree = ET.ElementTree(ET.XML(input_xml))
    result_tree = transform(xml_tree)
    html_str = ET.tostring(result_tree, encoding='unicode', method='html')
    return BytesIO(html_str.encode('utf-8'))
