Subject [jira] [Commented] (AXIOM-441) Fails to parse XML with empty default namespace attribute value

-----------------------------------

Hi Andreas,

AFAIK, I'm using the one coming with OpenJDK 7u3 (via Debian unstable):

paul@zitpcx6184:~$ dpkg-query -S /usr/lib/jvm/java-7-openjdk-i386/jre/lib/rt.jar
openjdk-7-jre-headless:i386: /usr/lib/jvm/java-7-openjdk-i386/jre/lib/rt.jar
paul@zitpcx6184:~$ dpkg-query -W openjdk-7-jre-headless:i386
openjdk-7-jre-headless:i386     7u3-2.1.3-1

Could you verify that Axiom is able to parse the above example XML?

I haven't delved into Axiom codebase, but the stacktrace makes it look like this is a problem
with Axiom --- assuming null is the correct response for 'bar' element's namespace, in this
case.

Cheers,

Paul.

> "The attribute value in a default namespace declaration MAY be empty. This has the same
effect, within the scope of the declaration, of there being no default namespace."

> <?xml version='1.0' encoding='UTF-8'?>
> <foo xmlns='http://example.org/'>
>     <bar xmlns=''>value</bar>
> </foo>
> The following code snippet (slightly modified from Axiom documentation) uses Axiom to
parse a String variable xmlData:

>         OMXMLParserWrapper builder = OMXMLBuilderFactory.createOMBuilder(in);
