PDF/A3 Attachment Extraction

In previous posts, we explored embedding documents within PDF/A-3 files using 4D Write Pro, including generating electronic invoices. As e-invoicing becomes mandatory in various European countries—such as France and Germany—the ability to extract embedded XML files from these PDFs is becoming crucial. But the utility of PDF/A-3 extends beyond invoices; these files can embed various document types that may require extraction.

While tools like Adobe Acrobat Reader offer manual extraction, this post introduces an efficient, automated method using 4D 20 R6 to easily handle the process.
