Hello xsd users,

I'm trying to use xsd to generate classes for ade for cityGML and I'm bumping into a problem that I can't resolve.
In cityGML, there is a lot of schemas and substituton elements, so I'll try to stay as simple as possible.

My problem is with substitution group. For most of them it works find, but I found a problem with basic type (mostly integer and boolean).

Here's the part sample of an xsd that failed :

<schema xmlns="http://www.w3.org/2001/XMLSchema" xmlns:bldg="http://www.opengis.net/citygml/building/2.0" xmlns:core="http://www.opengis.net/citygml/2.0" xmlns:gml="http://www.opengis.net/gml" xmlns:grp="http://www.opengis.net/citygml/cityobjectgroup/2.0" xmlns:utility="http://www.citygml.org/ade/utility/0.9.2" elementFormDefault="qualified" targetNamespace="http://www.citygml.org/ade/utility/0.9.2" version="0.9.2">

...

                <element name="buildingHabitants" substitutionGroup="bldg:_GenericApplicationPropertyOfAbstractBuilding" type="integer"/>

</schema>


With abstract building roughly define as :

<xs:complexType name="AbstractBuildingType" abstract="true">
                <xs:complexContent>
                               <xs:extension base="core:AbstractSiteType">
                                               <xs:sequence>
                                                               ...
                                                               <xs:element ref="_GenericApplicationPropertyOfAbstractBuilding" minOccurs="0" maxOccurs="unbounded"/>
                                               </xs:sequence>
                                </xs:extension>
                </xs:complexContent>
</xs:complexType>


Witch generate in the hxx file the following :
typedef ::xml_schema::type _GenericApplicationPropertyOfAbstractBuilding_type;



However, when I try to compile with this generated code, I've got an error :
error C2440: 'initialisation' ; impossible de convert from 'initializer list' to 'xml_schema::integer'


Any idea on the problem or when I should look at ?

Nicolas

Can you show the code fragment that triggers this error?

Also, there is quite a lot of information on GML and CityGML in the
mailing list archives which you can search here:

I investigate a little deeper, and I found out that there is a substitution problem with xlink substitute elements (for example,  <core:cityObjectMember xlink:type="simple"> )

If it's on any help, here's the options I used for xlink :

--root-element-all
--generate-inline
--generate-default-ctor
--generate-polymorphic
--polymorphic-type-all
--generate-forward
--generate-comparison

--omit-default-attributes

--extern-xml-schema xs/xml-schema.xsd
--hxx-prologue "#include "citygml_export.hpp""

I have the same options for gml, with 3 more :
--root-element Array
--root-element Bag

I investigate a bit further, and it seems the problem is on the new version of xsd.
On the 3.3.0 version, it works, but with the same options on the "4.1.0.a11" version,  it failed.

I'll keep using the 3.3 version for know, and the next release version.

Message-ID: <0a47d2a9fe2a4384842ec50585575912@Lizherel.cstb.local>

Hello all,

Sorry to bother you again, but I still have a problem with substitution groups and code generation.

Following the discussions about generated cityGML classes with xsd (version 3.3, as I have a problem with 4.1.0.a11).

I have this kind of simplified  xsd schema (the element witch cause me problem is in bold):

<xs:schema xmlns="http://www.opengis.net/citygml/building/2.0" xmlns:core="http://www.opengis.net/citygml/2.0"
                xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:gml="http://www.opengis.net/gml"
                targetNamespace="http://www.opengis.net/citygml/building/2.0" elementFormDefault="qualified" attributeFormDefault="unqualified" version="2.0.0">

                <xs:import namespace="http://www.opengis.net/gml" schemaLocation="../3.1.1/base/gml.xsd"/>
                <xs:import namespace="http://www.opengis.net/citygml/2.0" schemaLocation="cityGMLBase.xsd"/>

                <xs:complexType name="AbstractBuildingType" abstract="true">
                               <xs:complexContent>
                                               <xs:extension base="core:AbstractSiteType">
                                                               <xs:sequence>
                                                                              <xs:element ref="_GenericApplicationPropertyOfAbstractBuilding" minOccurs="0" maxOccurs="unbounded"/>
                                                               </xs:sequence>
                                               </xs:extension>
                               </xs:complexContent>
                </xs:complexType>

                <xs:element name="_GenericApplicationPropertyOfAbstractBuilding" type="xs:anyType" abstract="true"/>

                 <xs:element name="ElementTest" type="gml:CodeType" substitutionGroup="_GenericApplicationPropertyOfAbstractBuilding"/>

</xs:schema>


The parser works fine as a xml reader/writer, however there is no attribute generated with constructor and getter/setter for this element, so if in my code I can't do :
ElementTest anElement = new ElementTest ;


So my question is, is there a way to generate a class ElementTest or does it's impossible du to the xsd file definition ?

Thank in advance to anyone that spend time reading this.

Regards,
Nicolas.

XSD does not generate classes (I assume you meant "class" not
"attribute" above) for elements, only for types. So you need to
use ElementTest's (potentially dynamic) type in the above code
fragment.

It is clear to me that you don't understand how XSD maps XML
Schema constructs (types, elements) to C++ constructs (classes,
functions). So I would suggest that you read carefully through
the getting started guide:

https://codesynthesis.com/projects/xsd/documentation/cxx/tree/guide/

Hello Boris,

Thank you, but I read and re-read the documentation and I understand that elements are not part of the generated code.
However, in the generciApplicationOf substitution mecanism of cityGML, I have no choice on the xsd file.

for exemple with the previous xsd samplecode :

	<xs:complexType name="AbstractBuildingType" abstract="true">
		<xs:complexContent>
			<xs:extension base="core:AbstractSiteType">
				<xs:sequence>
					<xs:element ref="_GenericApplicationPropertyOfAbstractBuilding" minOccurs="0" maxOccurs="unbounded"/>
				</xs:sequence>
			</xs:extension>
		</xs:complexContent>
	</xs:complexType>
	<xs:element name="_GenericApplicationPropertyOfAbstractBuilding" type="xs:anyType" abstract="true"/>
    
    <xs:element name="Truitos" type="integer" substitutionGroup="_GenericApplicationPropertyOfAbstractBuilding"/>


 I've got a generated building with a list type of  xml_schema::type  for  _GenericApplicationPropertyOfAbstractBuilding().
>From there, I can extract the namespace and the type of the variable Truitos, but I can only get the data by switching back to the dom element...

My main problem is that I cant get do that :

Truitos test = dynamic_cast<Truitos>( building-> GenericApplicationPropertyOfAbstractBuilding().at(0) );

(or even replace Truitos by xml_schema::integer)

Regards,
Nicolas

Why can't you do that? Do you get an compile/runtime error?

Of course this is not going to work.

No, but the type "Truitos" doesn't exist in my generated classes. 
 
Also, I Think there is a problem on the substitution mecanisms for cityGML ADE. For exemple, when I have multiple <element> with the same type (another integer in this case) , the parser choose  the last one on the substitution mechanism.

I'm trying to create a really simple case to let you see the problem.
