This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
Although the OO file format -which is what that article talks about- is structurally somewhat similar to ODF (the family of file formats ODT belongs to), it is a different file format, so I don't think the article will help.
The JODConverter library -which uses OO behind the scenes- may help with his.
