How to retrieve the variables in a template

[vricosti]

Hi,

Sorry to ask here but I cannot find any example showing how to retrieve all the variables inside a template...
For instance with the following template:

Hello {{ name }}!

{% if score > 80 %}
I'm happy to inform you that you did very well on today's {{ test_name }}.
{% else %}
I'm sorry to inform you that you did not do so well on today's {{ test_name }}.
{% endif %}
You reached {{ score }} out of {{ max_score }} points.

I want to (name, score, test_name, max_score)

Thanks

@Test
    public void jinjaTest() {
        String template = "Hello {{ name }}!\n" +
                "\n" +
                "{% if score > 80 %}\n" +
                "I'm happy to inform you that you did very well on today's {{ test_name }}.\n" +
                "{% else %}\n" +
                "I'm sorry to inform you that you did not do so well on today's {{ test_name }}.\n" +
                "{% endif %}\n" +
                "You reached {{ score }} out of {{ max_score }} points.";

        Jinjava jinjava = new Jinjava();
        Node node = jinjava.newInterpreter().parse(template);

        List<String> result = new ArrayList<>();
        helper(node, result);
        System.out.println(result);
    }

    void helper(Node node, List<String> result) {
        if (Objects.isNull(node)) {
            return;
        }
        if (node instanceof ExpressionNode) {
            Token token = node.getMaster();
            if (token instanceof ExpressionToken) {
                result.add(((ExpressionToken) token).getExpr());
            }

        }
        if (!CollectionUtils.isEmpty(node.getChildren())) {
            for (Node child: node.getChildren()) {
                helper(child, result);
            }
        }
    }
