THotPDF.DetectFacturXInvoice Method

Detects a Factur-X or ZUGFeRD invoice attachment in a loaded document and exposes the attachment and XMP metadata needed for consistency validation

Declaration

function DetectFacturXInvoice(out AInfo: THPDFFacturXInvoiceInfo): boolean;

HPDFDoc

Name	Purpose
`AInfo`	Receives the detected invoice filename, XMP filename and namespace URI, document type, version, conformance level, XML guideline identifier, AF relationship, and decoded attachment MIME type

Returns True when a supported e-invoice XML attachment is detected

Call this method after LoadFromFile or LoadFromStream
The method reads the document XMP metadata and the EmbeddedFiles name tree without adding an XML DOM dependency
XMPNamespaceURI identifies the namespace bound to the XMP DocumentFileName property, while AttachmentMimeType decodes PDF name escapes such as #2F before returning the normalized MIME type
The THPDFFacturXInvoiceInfo record is a container-level summary and does not validate EN 16931 business rules
