Unprefixed namespaces serializing as xmlns:xmlns in AXIOM DOM implementation
----------------------------------------------------------------------------
Key: WSCOMMONS-105
URL: http://issues.apache.org/jira/browse/WSCOMMONS-105
Project: WS-Commons
Issue Type: Bug
Components: AXIOM
Environment: Windows XP, JRE 1.4.2, AXIOM1.1.1
Reporter: C Corvin
Priority: Minor
When transforming an AXIOM DOM document and outputting to another DOM format,
an attribute with prefix 'xmlns' and NCName 'xmlns' (creating a QName
representation 'xmlns:xmlns') is created. For example my input:-
<soapenv:Body...>
<element xmlns="http://example.com/...";> </element>
</soapenv:Body>
is seraialized to:-
<soapenv:Body...>
<element xmlns:xmlns="http://example.com/...";> </element>
</soapenv:Body>
This appears to be caused by the following two steps:-
1. In org.apache.axiom.om.impl.dom.ElementImpl - getAttributes(), when setting
the default attributes at line 1309 an attribute is created with name xmlns and
an OMNamespace added with prefix xmlns
2. In org.apache.axiom.om.impl.dom.AttrImpl - getName(), since OMNamespace is
not null, the code OMConstants.XMLNS_NS_PREFIX + ":" + this.attrName generates
the incorrect output.
I have patched my version of org.apache.axiom.om.impl.dom.AttrImpl with the
following code:-
public String getName() {
return (this.namespace == null) ? this.attrName
: (OMConstants.XMLNS_NS_PREFIX.equals(this.attrName) ?
this.attrName : OMConstants.XMLNS_NS_PREFIX + ":" + this.attrName);
}
That seemed to me to be the right thing to do.
I am not sure if anything needs to be done with getQName(). I don't have
enough knowledge of the whole chain to know.
