To produce a view of the document that has entity references expanded and does not expose the entity reference node itself, use the <code>whatToShow</code> flags to hide the entity reference node and set <code>expandEntityReferences</code> to true when creating the <code><aclass="el"href="classxercesc_1_1DOMNodeIterator.html"title="DOMNodeIterators are used to step through a set of nodes, e.g. ">DOMNodeIterator</a></code>.
