Local invoice viewer
Read invoice XML or extract the named XML attachment from a Factur-X PDF locally. No document upload, persistent storage or external stylesheet. PDF pages are never rendered; active PDF content is rejected. Your chosen package links to its existing validator; viewing does not run validation or establish recipient acceptance.
Open existing validator (separate consent)
Documents remain in this page memory until cleared or closed. Opening a validator does not transfer the document. Local XML parsing uses the existing libxml2 engine; PDF extraction uses the existing pinned pdf-lib. DTDs and entities are blocked. Unsupported attributes and advanced extensions remain available in XML. Existing package sources, hashes and notices.
