Display only the text items of an SVG file with QT

Question

I'm new to QT and I'm trying to display only the text items of an SVG file but it only works with the rectangle items. I use QSvgRenderer and the method setElementId of the class QGraphicsSvgItem. Does anyone know how to manipulate only text items with their id?

item = new QGraphicsSvgItem(QString( "SVG_Logo.svg"));
   
    renderer = new QSvgRenderer(QLatin1String("SVG Logo Highlights.svg"));

    total = new QGraphicsSvgItem();


    bool exist_rect = renderer->elementExists(QString("rect1055"));


    bool valid = renderer->isValid();

    std::cout<<"exist_rect:"<<exist_rect<<std::endl;
    std::cout<<"valid:"<<valid<<std::endl;

    total->setSharedRenderer(renderer);

    /* Work with rectangle but not text !!*/
    total->setElementId(QLatin1String("rect1055"));
