As answered by people managing Xml Viewer.app and Schema Validator.
Xml Viewer.app's answer

It provides readable invoice layouts alongside XML viewing and formatting, with document processing kept on your device. It is a focused option for users who need to view documents without adopting a full invoicing or accounting system.
Xml Viewer.app's answer
XML-Viewer.app combines a general-purpose XML viewer with electronic invoice rendering.
