    // first tree init
    myhtml_tree_t* tree = myhtml_tree_create();
    myhtml_tree_init(tree, myhtml);
    
    // parse html
    myhtml_parse(tree, MyENCODING_UTF_8, html, strlen(html));
    
    // print result
    // or see serialization function with callback: myhtml_serialization_tree_callback
    mycore_string_raw_t str = {0};
    myhtml_serialization_tree_buffer(myhtml_tree_get_document(tree), &str);
    printf("%s\n", str.data);
    
    // release resources
    mycore_string_raw_destroy(&str, false);
    myhtml_tree_destroy(tree);
