Namespace with no prefix - how?
How do you create a element with a namespace without any prefix,
something like this (?):
<Response xmlns="http://mynamespace.org">
<Status>100</Status>
</Response>
With the following code:
Element responseElement = doc.createElementNS(
"http://mynamespace.org", "Response" );
or
Element responseElement = doc.createElementNS(
"http://mynamespace.org", "Response" );
responseElement.setPrefix( "" );
or
Element responseElement = doc.createElementNS(
"http://mynamespace.org", "Response" );
responseElement.setPrefix( null );
the output is
<Response>
<Status>100</Status>
</Response>
The only way I can write out the namespace is via:
Element responseElement = doc.createElementNS(
"http://mynamespace.org", "Response" );
responseElement.setPrefix( "myprefix" );
.. which output like this:
<myprefix:Response xmlns:myprefix="http://mynamespace.org">
<myprefix:Status>100</myprefix:Status>
</myprefix:Response>
but I would preferrably have the xmlns="" without a prefix so that the
prefix do not have to be repeated for the child nodes.
What am I missing?

Yes, I guess I was unclear. The XPath has to have prefixes. The document
can have a default namespace, but XPaths cannot refer to it with a null
prefix.

Having said that ... the following still works:
the following xpath expression:
//mm100:MM7Version
works against:
<SubmitReq
xmlns="http://www.3gpp.org/ftp/Specs/archive/23_series/23.140/schema/REL-5-MM7-1-2">
<MM7Version>5.3.0</MM7Version>
</SubmitReq>
... using my custom PrefixResolver that you mentioned in the xalan
mailing list.

Thanks for that Jeff. Good you are on this list too ;) You saved some
grief.
For the mean time, I will have things fully-prefixed.

The XPath spec says you can't use XPath on this. Some versions of xalan
will let you do /:Response/:Status, but the authors claim it's a bug if it
works.

You're on the right track.
Element responseElement = doc.createElementNS(
"http://mynamespace.org", "Response" );
The question is what to do about the default namespace declaration.
THEORETICALLY, it shouldn't be needed by most DOM processing, only when
you write the document out to a file or SAX stream or whatever, and a good
XML serializer should realize that it has to automatically create the
default namespace declaration at that time.
If you have a DOM that prototypes DOM Level 3, you can run namespace
normalization and it will create the default namespace declaration (and
reconcile any other declarations, as necessary).
Or you can explicitly create it:
String namespaceForNamespaces="http://www.w3.org/2000/xmlns/";
responseElement.setAttributeNS(namespaceForNamespaces,"xmlns","
http://mynamespace.org");
See also the current DOM Level 3 Working Draft, section 1.1.10
(namespaces), Document.normalizeDocument(), and appendix B.1 ("Namespace
Normalization" pseudocode).
