This week's giveaway is in the EJB and other Java EE Technologies forum. We're giving away four copies of EJB 3 in Action and have Debu Panda, Reza Rahman, Ryan Cuprak, and Michael Remijan on-line! See this thread for details.
The question doesn't make sense. The data in the DOM is in an internal form, where the concept of "escaping" doesn't apply. When you convert that internal form to an XML document (e.g. a text file), then you might want to not escape certain data. That conversion is called "serializing". So you are asking a question about the serializer that you will choose to use, whatever it is.
