sdaiSaveModelAsXmlBNUnicode

This function saves the model as XML according to IFC2x3's way of XML serialization (wchar, i.e. Unicode file name).

Property model

Size: 64 bit / 8 byte (value)
The handle to the model. The model handle is static during its existance. Several models can be opened simultaniously within one session. Different models are always independent, threads are allowed to be running on different models simultaniously.

Property fileName

Size: 64 bit / 8 byte (reference)
The file name of the file as available in the file system in Unicode (wchar_t *). The given wchar_t array will not be adjusted. The size of each wchar_t element is depending on the OS, both 16 bit / 2 bytes wchar_t elements as well as 32 bit / 4 byte wchar_t elements are recognized and supported.

Example (based on pure API calls)

Here you can find code snippits that show how the API call sdaiSaveModelAsXmlBNUnicode can be used.

#include    "./include/ifcengine.h"
#include    <iostream>

void    OpenModel(
                const wchar_t   * fileNameIN,
                const wchar_t   * fileNameOUT
            )
{
    //
    //  The advised manner of opening an IFC (or ifcXML) file is by using embedded schema's that can be recognized automatically
    //

    SdaiModel   model = sdaiOpenModelBNUnicode(0, fileNameIN, L"");

    if (model) {
        SdaiInteger entityCount = engiGetEntityCount(model), instanceCount = 0;

        for (SdaiInteger i = 0; i < entityCount; i++) {
            SdaiEntity  entity = engiGetEntityElement(model, i);

            SdaiAggr    ifcInstances   = sdaiGetEntityExtent(model, entity);
            SdaiInteger noIfcInstances = sdaiGetMemberCount(ifcInstances);
                
            instanceCount += noIfcInstances;
        }

        std::cout << "entity count (schema): " << entityCount << "\n";
        std::cout << "instance count (ifc file): " << instanceCount << "\n";

        //
        //  Independent from the extension the file will be saved as ifcXML
        //
        //  Note: that IFC has two types of XML serialization, i.e. basic XML and simplified XML
        //        basic XML is used for IFC 2x3 TC1 and all versions before
        //        simplified XML is used for IFC 4 and anything later 
        //
        const char  * schema = nullptr;
        GetSPFFHeaderItem(model, 9, 0, sdaiSTRING, &schema);

        if (schema[0] == 'I' && schema[1] == 'F' && schema[2] == 'C' && schema[3] == '2') {
            sdaiSaveModelAsXmlBNUnicode(model, fileNameOUT);
        }
        else {
            sdaiSaveModelAsSimpleXmlBNUnicode(model, fileNameOUT);
