Replace XFA Data

XFA (XML Forms Architecture) forms store their data in XML format within the PDF structure. In this example, the Form facade from the aspose.pdf.facades module is used to bind a PDF and replace its existing XFA dataset using an external XML stream. After applying the new data, the updated PDF is saved as a separate file.

1. Initialize pdf_facades.Form() to manage XFA form data.
2. Call ‘bind_pdf()’ to attach the PDF containing XFA forms.
3. Use ‘FileIO()’ to read the XFA XML file.
4. Call ‘set_xfa_data()’ to update the PDF with new XFA content.
5. Save the updated Document.

from io import FileIO
import sys
from os import path
import aspose.pdf as ap
import aspose.pdf.facades as pdf_facades

sys.path.append(path.join(path.dirname(__file__), ".."))

from config import set_license, initialize_data_dir


# Replace from XFA data
def replace_xfa_data(infile, datafile, outfile):
    """Import form data from XFA file into PDF form fields."""
    # Create Form object
    form = pdf_facades.Form()

    # Bind PDF document
    form.bind_pdf(infile)

    # Open XFA file as stream
    with FileIO(datafile, "r") as xfa_stream:
        # Import data from XFA into PDF form fields
        form.set_xfa_data(xfa_stream)

    # Save updated PDF
    form.save(outfile)
