Identifying executable hashes from a partial appx bundle

Scenario: You only have the AppxBlockMap.xml from a potentially malicious Appx. You'd like to identify the original PE contained in the Appx.

AppxBlockMap.xml contains a list of files and their hashes contained in an Appx bundle. Each file is contained in a <File></File> xml block. You can search for the string <File Name= to see each file or search directly for the relevant .exe. The file hash is the last element (<b4:FileHash>) and is base64 encoded.
