Right, this might be more than 2x if the original subtree hasn't been fully materialized. > As I see, problem not in the amount of text data, but in the # of > elements in the source subtree, I have around 3M elements. > > I've tried adoptNode, but that does not work for me, null returns, I'll > try more... adoptNode() will return null if the source node comes from an implementation which is not compatible with the target document. Can you check what the names of the DOMImplementation classes (i.e. call docNode.getImplementation().getClass().getName()) are for both the source and target? Any combination of org.apache.xerces.dom.DOMImplementationImpl and org.apache.xerces.dom.DeferredDOMImplementationImpl should be compatible with each other. > Thanks.
