An applicant can instantiate a parsing framework, provide an input stream, attach observers, and initiate parsing, which inverts control to the parsing framework. The parsing framework can have an observer manager, a parser controller, and parsers. The observer manager manages observer design patterns from which the observers are instantiated. The parser controller determines which parser would be appropriate for parsing the input stream and instantiate the appropriate parser(s). The parser controller gets the callbacks from the parsers and communicates outcomes to the observer manager. The observer manager determines which of the observers is to be notified, generates parsing notifications accordingly, and dispatches the parsing notifications directly to the observers. The application can be any application that needs parsing in an electronic information exchange platform. The input stream can be created by the application opening a document received from a backend system communicatively connected to the electronic information exchange platform.
