Export to XML

Exporting form data allows developers to reuse information stored in PDF AcroForms without manually copying field values. In this example, a Form object is created from the aspose.pdf. In the facades module, the source PDF is bound to it, and the form data is written to an XML stream.

1. Create a Form Object. Initialize pdf_facades.Form() to access and manage form fields.
2. Use ‘bind_pdf()’ to attach the source PDF document to the Form instance.
3. Create a writable file stream using ‘FileIO()’.
4. Call ’export_xml()’ to extract all form field values and write them into the XML file.

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


# Export Data to XML
def export_pdf_form_data_to_xml(infile, datafile):
    """Export PDF form data to XML file."""
    # Create Form object
    pdf_form = pdf_facades.Form()

    # Bind PDF document
    pdf_form.bind_pdf(infile)

    # Open XML file as stream
    with FileIO(datafile, "w") as xml_output_stream:
        # Export data from PDF form fields to XML
        pdf_form.export_xml(xml_output_stream)
