> 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.
