However, it is provided in exchange spec's start and of each field. How should I write parser for data I recveive? I am new to parser consept and apprecite your suggestion. I am putting following example data string just to insist my scenario

I need to decode it(as per spec) as: Messate type: 1001 UserID: TX password: PASSWORD session: SESSION data: N
