Subject: [xsd-users] Serialization issue with Latin characters
Message-ID: <CADHZ71iMbkYfWFa7TgR2j06PJfivGmCcAqsoDvP=Hwps_LfsoQ@mail.gmail.com>

I am facing an issue related to  serialization.

My xsd:
<xs:complexType name="Sample" abstract="false">
        <xs:attributeGroup name="SampleAttributes">
                <xs:attribute name="n.Id" type="xs:string" use="optional"/>
        </xs:attributeGroup>
        </xs:complexType>
</xs:schema>

I have used xsd cxx-tree to generate classes from xsd.

I am able to serialize xml for normall english characeters but getting
exception while using the value "Union pour le financement d'Immeubles de
Soci?t?s"

Throwing exception when I serialize the object. I found that this is because
of some spl charaters in "Soci?t?s"

So I tried with wchar_t commandline option;

Now I am not getting exception while serialization but the XML string looks
not correct:

<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<Sample>
 <Id="Union pour le financement d'Immeubles de Soci?????t?????s" />
</Sample>

Any help really appriciated. Please ask me if you  need any more
info..Thanks in advance.

This is because by default XSD assumes that the object model text is
encoded in UTF-8. '?t' in Soci?t?s is not a valid UTF-8 character
sequence.

The easiest way to resolve this is probably to switch to the ISO8859-1
(aka Latin1) encoding using the --char-encoding XSD compiler option:

--char-encoding iso8859-1

See the XSD compiler command line manual (man pages) for details:

These comparisons are there to detect special values (INF, NaN, etc)
which have to be serialized specially.

#pragma GCC diagnostic is only supported in GCC 4.6 and up. Also, I
tried to reproduce this since we don't get these warnings in our
test builds. It seems that this warning has to explicitly requested
with the -Wfloat-equal option. -Wall doesn't turn it on, not even
-Wextra. I think that tell us that this warning is pretty useless
because of the noise it creates. So my suggestion would be to remove
the -Wfloat-equal option from your GCC command line.

This is actually the correct encoding of '?' in UTF-8. See that
encoding="UTF-8" attribute in the XML declaration? That means the
document is in UTF-8 even though your application internally is
using ISO8859-1. Generally, the input XML encoding, application
encoding, and output XML encoding can all be different.

If you want your XML to also be in ISO8859-1 (by default it is
UTF-8), you will need to specify this encoding when calling one
of the serialization functions, for example:

root (std::cout, obj_model, map, "ISO8859-1");

Subject: [xsd-users] Using both cxx-tree and cxx-parser in one application
Message-ID: <012b01cc71a4$74277560$5c766020$@Roberts.name>

I have an application where I want to use cxx-parser to read in detailed
information based on one xml-schema, but would like to output summary
information using another xml-schema using cxx-tree after building its
object model from the detailed one.  The two schema have some common
elements but I don't want  to be locked into being forced to conform to the
summary schema.

 

Is it possible to have both cxx-parser and cxx-tree in one application?

 

I have tried this, but I am having trouble with common typedefs between the
two, e.g. these, amongst others, appear to have both a tree version and a
parser version:

typedef ::xsd::cxx::tree::buffer< char > buffer;

typedef ::xsd::cxx::tree::flags flags;

typedef ::xsd::cxx::tree::properties< char > properties;

 

I am guessing that smart use of namespaces or header file inclusions may
work, but I would appreciate a little guidance about how to do this.

 

Best regards,
Vaughan

Yes, that should be possible. You will need to re-map the XML Schema
namespace (xml_schema) for one of the mappings. For example, you could
add:

--namespace-map http://www.w3.org/2001/XMLSchema=xml_schema_tree

When compiling with cxx-tree and:

--namespace-map http://www.w3.org/2001/XMLSchema=xml_schema_parser

When compiling with cxx-parser.

Also, if you use schemas with the same namespace in both mappings,
then you will need to map them to different namespaces as well.

See the XSD compiler command line manual (man pages) for details
on the --namespace-map option:

Thanks Boris!
I set the xsd namespace-map compiler option in the cxx-tree version as
suggested below and that did the trick.

Message-ID: <C095075EFE4555448CC3B876612DA9820109306CAF@HVXMSPA.us.lmco.com>

Hi,

We are using CodeSynthesis XSD to generate C++ code from a set of XSD's that we have created and we have run into a potential issue.  Several of the complexTypes defined in our schemas include polymorphic sequences.  We have defined some sequences as sequences of some parent type but we would like to put child type instances in them.  In our tests we have been able to put pointers to child type instances in the sequences - but when we serialize to XML the resulting XML does not seem to reflect the child instances.

Is there something we are doing wrong?

Thanks!
Jason

Example Code:
// create a MessageType object from XML string - this works!
std::istringstream iss (xml);
auto_ptr<MessageType> mfs (Message (iss));

// create a ChildType object (subclass of ParentType) - this works!
auto_ptr<ParentType> pt(new ChildType());

// add ChildType to MessageType Payload sequence - this works!
mfs->Payload().push_back(pt);

cout << endl << "-------------------------------------" << endl
        << "Message with ChildType payload ";

// verify that element 0 is a ChildType - this works! - prints "valid derived pointer"
ChildType *e0 = dynamic_cast<ChildType*>(&mfs->Payload()[0]);
if (e0)
        cout << "(valid derived pointer)" << endl << endl;
else
        cout << "(invalid derived pointer)" << endl << endl;

// display XML of modified MessageType object - this does not work! - the XML printed here does not reflect the ChildType instance - only that a ParentType has been included
Message (cout, *mfs, map);

Your code looks fine to me. Have you compiled your schemas with the
--generate-polymorphic option and used the --polymorphic-type option
to mark ParentType as the root of a polymorphic type hierarchy?

See the XSD compiler command line manual (man pages) for more
information on these options:

Thanks!  Using "--polymorphic-type ParentType" when generating the C++ code seems to work for us.  It seems like CodeSynthesis was not automatically recognizing ParentType as the root of a polymorphic type hierarchy (probably because we're not using "substitutionGroup" declarations in our XSD's.  We are now seeing the result we're expecting when serializing to XML.

Thanks,
Jason

Hi,

As I didn't find anything about that, I'm supposing it's not possible but I
need to be sure :

Once I've parsed an xml file and get the C++ instances (wich types are
generated using xsd),
given one object, is there a way to get the parent object, that is the
object that contains this object?

I don't see anything like that in the code but I'm not sure so can you
confirm that it's not possible?

Thanks.
