org.apache.axiom.om.impl.dom.ElementImpl class's hasAttributes() and
getAttributes() methods are not compatible with DOM interfaces.
------------------------------------------------------------------------------------------------------------------------------------
Key: WSCOMMONS-557
URL: https://issues.apache.org/jira/browse/WSCOMMONS-557
Project: WS-Commons
Issue Type: Bug
Components: AXIOM
Affects Versions: Axiom 1.2.10
Environment: Ubuntu, JDK 1.6
Reporter: Amila Jayasekara
The class org.apache.axiom.om.impl.dom.ElementImpl implements both DOM Element
and OMElement interfaces. According to DOM API the method hasAttrbutes() should
return true if there are attributes attached to current node. Also this method
will return true if there are namespaces attached to current node. But
according to current implementation the ElementImpl class only checks for
namespace nullability. This code will fail if we have a xml like follows,
<?xml version='1.0' encoding='utf-8'?>
<soapenv:Body xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";
xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd";
wsu:Id="Id-739587016">
<GetDirectionsResponse xmlns="http://www.example.org/webservices/";>
<GetDirectionsResult>
<drivingdirections xmlns="">
<route distanceToTravel="500m" finalStep="false" id="0">Head south on
Grove St</route>
</drivingdirections>
</GetDirectionsResult>
</GetDirectionsResponse>
</soapenv:Body>
In above xml the node "drivingdirections" is having an empty namespace. But for
"drivingdirections" node, the method "hasAttribute()" should return true, as
there is a namespace attached to it. But current implementation of ElementImpl
returns false.
Also getAttributes() method should return empty namespace ("xmlns=\"\"") for
"drivingdirections" node. Current implementation doesnt return empty namespace
as an attribute. Since namespace of drivingdirections is empty, namespace of
child elements of "drivingdirections" are also null. Therefore hasAttribute()
method will return false for even elements like "route". ("route" element has
attributes, therefore hasAttribute() should return true)
There are 2 rampart issues which depends on this.
