Hi, I'm not sure this answers your question, but GWT does have an XML
API, see [1].
FWIW I did do some work previously with GWT and XML, but the lack of a
createElementNS method was a real blocker. You can seach an XML
document in a namespace aware manner, because the Node interface has a
getNamespaceURI() method, but you cannot build an XML document with
namespaces, except by constructing the document as text, then calling
XMLParser.parse(). If you want to create a code editor, that may be a
valid workaround for you. I did write some convenience code to work
around this a while ago, see [2], however this is a bit of a hack, and
I've since moved away from GWT to using XForms and Orbeon [3] for that
particular project, because of the much better XML support.
