What are the ways to develop a Book like app?

I have a situation here, I want to replicate an app which will look like a book for content of book I'll have a XML feed that feed will have information pertaining to contents and number of pages.

The situation is number of pages will vary every time so can you suggest me a way to show varied number of pages every time + how to apply the flip animation while user is browsing these pages.

Please enlighten me on this.
