Please provide a code snippet for xml to pdf using a style sheet using python.
Please provide a fastest solution possible and provide the resources to explore more.
I tried aspose.cells did not work file cannot be opened.
To convert CCDA XML files to PDF using a stylesheet in Python, you can utilize the lxml library for XML processing and reportlab for PDF generation. Below is a code snippet that demonstrates how to apply an XSLT stylesheet to your XML and then create a PDF:
from lxml import etree
from reportlab.lib.pagesizes import letter
from reportlab.pdfgen import canvas
# Load your XML and XSLT files
xml_file = 'your_file.xml'
xslt_file = 'cda.xsl'
# Parse the XML and XSLT
xml_doc = etree.parse(xml_file)
xslt_doc = etree.parse(xslt_file)
# Transform the XML using the XSLT
transform = etree.XSLT(xslt_doc)
result_tree = transform(xml_doc)
# Create a PDF
pdf_file = 'output.pdf'
c = canvas.Canvas(pdf_file, pagesize=letter)
# Write the transformed XML content to the PDF
for line in str(result_tree).splitlines():
c.drawString(100, 750, line)
c.showPage()
c.save()
Ensure you have the required libraries installed:
pip install lxml reportlab
This code reads your XML file, applies the XSLT transformation, and generates a PDF with the transformed content. You may need to adjust the PDF generation section to format the output according to your requirements.
If you have any further questions, feel free to ask!
i askef for solution using aspose products
Using Aspose.Cells for Python might not work well because that library is specialized for Excel spreadsheets and not for general XML+XSLT transformations to PDF. You can use Aspose.PDF library, which supports loading XML efficiently and applying XSLT to produce a styled PDF for your requirements. See the document for your reference: Creating PDF from XML using XSLT|Aspose.PDF for .NET
Also, check the article/page for your reference: How to Convert XML to PDF in Python
Moreover, my colleagues from Aspose.PDF team will evaluate your requirements in details and assist you precisely soon. @asad.ali FYI.
import aspose.pdf as pdf
license = pdf.License()
license.set_license(“Aspose.TotalforPythonvia.NET.lic”)
document = pdf.Document()
document.bind_xml(r"52153_09262025_115241.xml")
document.save(“XMLtoPDF.pdf”)
print(“XML to PDF Converted Successfully”)
The converted document is not opening and has size 2kb actual file size 830kb
These are medical ccda xml files.
Could you please zip and attach your input XML document and output PDF file. We will look into your issue soon.

i have attached expected output,aspose output,the style sheet which we use
Thanks for the sample files.
We will evaluate your issue using your resource files and get back to you soon.
