An aside, but the correct namespace uri for html-in-xml-format is http://www.w3.org/1999/xhtml and getting it wrong is likely to break whatever you're doing further down the line. > Per the api, to create the root element with a namespace, I've gotta call > xmlNewNode with an xmlNs* argument.

See this post and the related thread: <http://mail.gnome.org/archives/xml/2008-June/msg00069.html> Also some example code: <http://mail.gnome.org/archives/xml/2008-August/msg00046.html> > My present cowardly code includes the namespace in the name, like: > > xmlNode* rootelem = xmlNewNode(NULL, (xmlChar *) "h:html"); No, that is including the prefix in the name, not the namespace, the upshot of which means you're falling back to pre-Namespaces-in-XML behaviour. You want to only give local-names (the bit after the colon) to the node creation functions, along with a namespace object. Hope the previous mailinglist threads are enough to get you on the right track, Martin _______________________________________________ xml mailing list, project page http://xmlsoft.org/ [email protected] http://mail.gnome.org/mailman/listinfo/xml
