[xsd-users] Inconsistency in Qname serialization/parsing

Mon Dec 17 12:11:58 EST 2012

Hi Boris,

First of all, thank you for providing such tool as xsd-cs, this is really
helpful for C++ developpers.

Now, unfortunately, I face an issue I am not able to solve without
consulting you.

I am trying to serialize and then parse a Soap Fault with xsd-cs.
Here is the output:

--------------------------------
       SERIALIZING fault
--------------------------------
<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<Envelope xmlns="http://www.w3.org/2003/05/soap-envelope">
  <Header/>
  <Body>
    <Fault>
      <Code>
        <Value>Server</Value>
      </Code>
      <Reason>
        <Text xml:lang="en">Error : invalid message</Text>
      </Reason>
    </Fault>
  </Body>
</Envelope>

--------------------------------
       PARSING fault
--------------------------------
parsing : error during validation: message 01:17:30:value 'Server' not in
enumeration

Indeed, the element "Value" element must respect :
(see http://www.w3.org/2003/05/soap-envelope)

  <complexType name="faultcode">
    <sequence>
      <element name="Value" type="env:faultcodeEnum" />
      <element name="Subcode" type="env:subcode" minOccurs="0" />
    </sequence>
  </complexType>

  <simpleType name="faultcodeEnum">
    <restriction base="xs:QName">
      <enumeration value="env:DataEncodingUnknown" />
      <enumeration value="env:MustUnderstand" />
      <enumeration value="env:Receiver" />
      <enumeration value="env:Sender" />
      <enumeration value="env:VersionMismatch" />
    </restriction>
  </simpleType>

Here, when serializing, xsd-cs builds and xml message without prefixing the
namespace of the root element ; hence the "Value" text is not qualified by
any prefix, which is fair.

But then, the parsing should be in line with this logic, and this is not
the case : the error message shows that a prefix is expected.

Note that I cannot use the namespace infomap to force a prefix because I am
parsing and serializing the xml data with the generic
element_map/element_type logic.

Here is an extract that shows how I build the body of the fault:

            aBody.fault(
                soapEnv::Fault
                (
                    soapEnv::Faultcode
                    (
                        soapEnv::FaultcodeEnum
                        (

xml_schema::Qname(soapEnv::EnvelopeElement::namespace_(),"Server")
                        )
                    ),
                    aFaultReason
                )
            );

Could you tell me how to deal with qname elements and more generally how to
parse/serialize them in a soap fault context with xsd-cs ?

Many thanks,
Brice
