DetectFacturXInvoice

Document properties

Description

Checks whether the current document contains recognizable e-invoice XML and reads the basic identifiers from XMP and XML metadata

Syntax

Delphi

Function TPDFlib.DetectFacturXInvoice: Integer;

Return values

0	No recognizable e-invoice XML was found
1	Recognizable e-invoice XML was found

Remarks

Detection first uses the XMP DocumentFileName value, then tries factur-x.xml, xrechnung.xml, zugferd-invoice.xml, and ZUGFeRD-invoice.xml

After a successful call, use GetFacturXInvoiceInfo to read the file name, version, conformance level, guideline ID, and /AFRelationship

Example

// Check whether the loaded PDF carries invoice XML
begin
  if PDF.DetectFacturXInvoice = 1 then
    InvoiceFileName := PDF.GetFacturXInvoiceInfo(1);
end;
