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, David
