> If you want to implements `json path` param, you can refer to the
following ideas:如果要实现 `json 路径`参数，可以参考以下思路： First, replace
`SimdJSONParser::Element` with `JsonbDocument`.首先，将 `SimdJSONParser：：Element`
替换为 `JsonbDocument`。 Second, find all elements that match the
path.其次，找到与路径匹配的所有元素。 Third, use the elements find in second step as the root
element to find their child elements.第三步，使用第二步中找到的元素作为根元素来查找其子元素。

{"y":"bcd"}]', 'all', '10', null, '$[*][*]');

ok，I'll think about it. Except for the first step, my solution is no
different from yours. I'll look at JsonDocument.
