Carpet spot removal approach app for mobile tablet/phone

Would like app to allow user to drill down (up to 4 levels) from a menu to read the information about the proper process required to clean a particular type of spot in a carpet. The total text is quite lengthy (30 total pages in a Word document). In a perfect world, I would have the ability to add/modify the text via xml but I don't know if that's possible or feasible.
