You're probably right. Java objects have an awful lot of built-in memory
overhead just for the java.lang.Object base class, and if you naively create
a separate object for every element, attribute, attribute value, text chunk,
and so on, you end up with a very large in-memory data structure. Memory
aside, Java object creation and deletion is also very slow (that's why it
takes so long to load an XML document into a DOM).
All the best,
