Export to XFDF

XFDF is an XML representation of PDF form data that allows developers to transfer form field values independently from the original document. In this example, the Form object from aspose.pdf.facades is used to bind the source PDF and export its data into a structured XFDF file.

1. Initialize pdf_facades.Form() to manage PDF form data.
2. Call ‘bind_pdf()’ to attach the source PDF document.
3. Use ‘open()’ to create a writable binary stream.
4. Export Form Data. Call ’export_xfdf()’ to extract and save form field values in XFDF format.

def export_pdf_form_to_xfdf(infile, outfile):
    """Export PDF form data to XFDF file."""
    # Create Form object
    pdf_form = pdf_facades.Form()

    # Bind PDF document
    pdf_form.bind_pdf(infile)

    # Create XFDF file stream
    with open(outfile, "wb") as xfdf_output_stream:
        # Export form data to XFDF file
        pdf_form.export_xfdf(xfdf_output_stream)
