After digging into the doc, I was able to fix it and to access the levels 3,4,.... Sorry ;-)

    private void processBlock(StructuralNode node) {
        List<StructuralNode> sections = node.getBlocks();
        for (int i = 0; i < sections.size(); i++) {
            final StructuralNode currentBlock = sections.get(i);
            System.out.println("Node : " + currentBlock.getContext() + ", title \"" + currentBlock.getTitle() + "\"");

            if ("section".equals(currentBlock.getContext())) {
                List<StructuralNode> subLevels = currentBlock.getBlocks();
                for (int j = 0; j < subLevels.size(); j++) {
                    final StructuralNode subLevel = subLevels.get(j);
                    if (subLevel.getTitle() == null) {
                        System.out.println("  Node : " + subLevel.getContext());
                    } else {
                        System.out.println("  Node : " + subLevel.getContext() + ", title \"" + subLevel.getTitle() + "\"");
                    }
                }
            }
