I don't either, but I haven't followed the discussions and Java strings give me a headache. > You don't happen to have a code snippet around that does exactly that > (Java)? I don't do Java any more (see headache above). The xmltooling code underneath opensaml-j, which I didn’t write, has helper routines that provide one way to do it, and they appear to use a DOM3 LSSerializer: public static void writeNode(Node node, Writer output) { DOMImplementation domImpl = node.getOwnerDocument().getImplementation(); DOMImplementationLS domImplLS = (DOMImplementationLS) domImpl.getFeature("LS", "3.0"); LSSerializer serializer = domImplLS.createLSSerializer(); LSOutput serializerOut = domImplLS.createLSOutput(); serializerOut.setCharacterStream(output); serializer.write(node, serializerOut); } There's also a pretty-print version that seems to be similar to what you're doing but not exactly the same. -- Scott
