Hey Steve, if I remember correctly, you should create your elements with the corresponding namespace they are actually contained.
defaultNS = L"http://tempuri.org/DefaultNamespace";; doc = domImplementation->createDocument(defaultNS, L"sample", nullptr); root = doc->getDocumentElement(); root->setAttributeNS(L"http://www.w3.org/2000/xmlns/";, L"xmlns:an", L" http://tempuri.org/AnotherNamespace";); node = document->createElementNS(L"nodeName", defaultNS); // providing the element with the default namespace should remove the empty `xmlns` attribute In regards to setAttributeNS, you should read its API description - especially the "Exceptions" part. The use can be a bit confusing otherwise. Hope it helps and good luck :) René 2017-05-18 17:14 GMT+02:00 Vitaly Prapirny <m...@mebius.net>: > Hi Steve, > > Sorry for my late reply.
