detach() is the best & most efficient approach. It all boils down to do you want to create new nodes or reuse old ones and save the construction. addElement() will always create new nodes. appendContent() is OK if you want to append the content of one Element to another but will also result in node creation. > And is there going to be a helper method for adding a > bit of static xml a la "<someTag><otherTag>text > content</otherTag></someTag>"?

String xml = "<someTag>...</someTag>"; Document doc = DocumentHelper.parseText( xml ); // add <someTag> to a new destination Element destination = ...; destination.add( doc.getRootElement().detach() ); James _________________________________________________________ Do You Yahoo!?
