Abstract:

In addition to being open source, saving as XML makes OpenOffice truly open. Aside from being open source, XML's self-documenting nature allows us to dive into the document format without having to dive into C++. And more significantly, XML allows us to use simple, free tools to manipulate the documents themselves. In this article we will examine the structure of the format.
