Axiom add unparsable namespace elements when there is an empty namespace in an
XML message
------------------------------------------------------------------------------------------
Key: AXIOM-386
URL: https://issues.apache.org/jira/browse/AXIOM-386
Project: Axiom
Issue Type: Bug
Components: API
Affects Versions: 1.2.9
Environment: Ubuntu, Linux
Reporter: Amila Jayasekara
I have following XML,
<?xml version='1.0' encoding='utf-8'?><soapenv:Envelope
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";
xmlns:xenc="http://www.w3.org/2001/04/xmlenc#";>
<soapenv:Body
xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd";
wsu:Id="Id-687052362">
<soapenv:Fault>
<faultcode>soapenv:Server</faultcode>
<faultstring>For input string: "1er"</faultstring>
<detail/>
</soapenv:Fault>
</soapenv:Body>
</soapenv:Envelope>
When this is parsed through AXIOM-API, i get following,
<?xml version="1.0" encoding="UTF-8"?>
<fragment
xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd";
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";
xmlns:xenc="http://www.w3.org/2001/04/xmlenc#";>
<soapenv:Fault 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";
xmlns:xenc="http://www.w3.org/2001/04/xmlenc#";>
<faultcode xmlns:axis2ns34="">soapenv:Server</faultcode>
<faultstring xmlns:axis2ns35="">For input string: "1er"</faultstring>
<detail xmlns:axis2ns36=""></detail>
</soapenv:Fault>
</fragment>
Note that some empty namespaces (xmlns:axis2ns34="") are added to <faultcode>
elements. These elements cannot be parsed using a SAX parser.
When parse through SAX we get following exception,
[Fatal Error] :1:493: The value of the attribute
"prefix="xmlns",localpart="axis2ns34",rawname="xmlns:axis2ns34"" is invalid.
Prefixed namespace bindings may not be empty.
org.xml.sax.SAXParseException: The value of the attribute
"prefix="xmlns",localpart="axis2ns34",rawname="xmlns:axis2ns34"" is invalid.
Prefixed namespace bindings may not be empty.

We should not re-declare namespaces for elements with empty namespaces.
Thanks
