Howto suppress empty ' xmlns=""' ? Using SOAP-WSDL-2.00.10 on v5.8.9 built for MSWin32-x86-multi-thread. I'm writing a client for a SOAP server which doesn't accept xmlns="" in start tags of parent elements. Is there an option in SOAP::WSDL to suppress such empty namespace attributes ? Ruedi Rüegg

Hi Ruedi, the 'xmlns=""' attribute is - usually - not a bug. You probably get SOAP messages like this: <soap:Envelope xmlns:soap="..."> <soap:Body> <foo xmlns="uri:bar"> <baz xmlns=""> </baz> </foo> <soap:Body> <soap:Envelope> This is equivalent to <f:foo xmlns:f="uri:bar"> <baz> </baz> </f:foo> If you want the child elements of the top level element to be unqualified, set the elementFormDefault="unqualified" attribute in the XML Schema. SOAP::WSDL defaults to "qualified" (which actually is a bug, but is intentionally left unfixed up to now, because fixing would possibly break older clients. I'll add the ability to set the default some time, and then fix it). Martin Am Mittwoch, den 12.05.2010, 15:22 -0400 schrieb Ruedi Rueegg via RT: Show quoted text

Hi Martin, 1) Setting elementFormDefault="unqualified" in the schema of the WSDL and recreating the perl bindings with wsdl2perl results in empty 'xmlns=""' attributes of the top level elements (1), e.g. <SOAP-ENV:Envelope xmlns:xsi="..."> <SOAP-ENV:Body> <requestMsg xmlns="http://..."> <header xmlns=""> (1) <timeStamp>2010-05-17T09:10:11Z</timeStamp> </header> <payload xmlns=""> (1) <entityIdentification> <subscriptionID>SAM:SER:1234</subscriptionID> </entityIdentification> ... soapUI 3.5 does not validate this message but accepts a non empty attribute <header xmlns="http://..."> or its omission <header> ... <payload> 2) With the default elementFormDefault="qualified" the 'xmlns=""' appears as attribute of the child elements of complex types (2). This is not accepted by the SOAP server. <SOAP-ENV:Envelope xmlns:xsi="..."> <SOAP-ENV:Body> <requestMsg xmlns="http://..."> <header> <timeStamp>2010-05-17T09:20:22Z</timeStamp> </header> <payload> <entityIdentification xmlns=""> (2) <subscriptionID xmlns="http://...">SAM:SER:1234</subscriptionID> </entityIdentification> ... soapUI 3.5 does not validate this message but accepts the non empty attribute <entityIdentification xmlns="http://..."> or its omission <entityIdentification> 3) soapUI (and eclipse WPT) creates from the WSDL (elementFormDefault="qualified") a valid request (with namespace prefixes), e.g. <soapenv:Envelope xmlns:soapenv="http://..."> <soapenv:Header/> <soapenv:Body> <v1:requestMsg xmlns="http://..."> <v1:header> <v1:timeStamp>2010-05-17T09:30:22Z</v1:timeStamp> </v1:header> <v1:payload> <v1:entityIdentification> <v1:subscriptionID>SAM:SER:1234</v1:subscriptionID> </v1:entityIdentification> ... Is there a way to use the set_prefix of SOAP::WSDL::Client to achieve this ? Ruedi

Hi, this sounds like SOAP::WSDL gets something wrong with nested complex types. There's a canonical XML form all XML can be transformed into (no matter whether using prefixes or the xmlns="..." attribute), and from your example it looks like SOAP::WSDL misinterprets at least one namespace.

>From your example, there should be no xmlns="" necessary, as all child

elements are in the same namespace, and the elements are supposed to be namespace-qualified. Can you provide a WSDL provoking this error? Martin Am Montag, den 17.05.2010, 09:59 -0400 schrieb Ruedi Rueegg via RT: Show quoted text

Hi, Attached is Tst.wsdl that shows this behaviour. The resulting SOAP-request contains the empty 'xmlns=""' on line 8. <SOAP-ENV:Envelope xmlns:xsi="..."> <SOAP-ENV:Body> <requestMsg xmlns="http://..."> <header> <timeStamp>2010-05-18T09:33:16Z</timeStamp> </header> <payload> <entityIdentification xmlns=""> <subscriptionID xmlns="http://...">SAM:SER:1234</subscriptionID> </entityIdentification> </payload> </requestMsg> </SOAP-ENV:Body> </SOAP-ENV:Envelope> Ruedi
