Как преобразовать xml в json в wso2

Сценарий Я реализовал API, который делает мыльный вызов внешней службе. Мне нужно преобразовать ответ из xml в json (что на самом деле и происходит). Но почему-то я не могу преобразовать вложенные узлы xml в json.

API

Вопрос Мой точный вопрос: как я могу преобразовать вложенный xml в json? Поскольку он преобразовал первые два узла xml, но третий узел xml не был преобразован.
