Помогите люди добрые тесткейсом у кого найдется, или советом чего не так в коде.
Прокомментировал основной метод "addComments". Вызывающий метод вроде как у всех.
А не проходит решение в итоге по 3м пунктам. Изучил уже все вопросы и рекомендации в обсуждении, не понимаю в чем ошибка.
Вывод xml похож на правду:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<first>
<!--it's comment-->
<second>some string</second>
<!--it's comment-->
<second>
<![CDATA[need CDATA because of <second>]]>
</second>
<!--it's comment-->
<second/>
<forth>
<!--it's comment-->
<second>some string</second>
<!--it's comment-->
<second>
<![CDATA[need CDATA because of <second>]]>
</second>
</forth>
<fifth>
<![CDATA[need CDATA because of "]]>
</fifth>
</first>package com.javarush.task.task33.task3309;
