Как хранить несколько значений узлов XML с разбитыми строками на основе идентификатора в базе данных?

Question

Я проанализировал xml-ответ от веб-службы, используя анализатор DOM.Я установил некоторые стандартные поля в классе SessionStdFields.java, поля, которые не совпадают, будут назначены как настраиваемые поля, определенные в классе SessionCustomFields.java, который встраивается в класс SessionStdFields с аннотацией @ElementCollection.

Пока все просто отличносинтаксический анализатор встречает такие узлы, как speaker, sessionTime и т. д. Он хранит несколько данных в одном столбце, на который ссылается идентификатор, но я хочу, чтобы он сохранялся таким образом, чтобы эти столбцы были разбиты на строки, на которые ссылается их идентификатор.

This is snippet of xml response from WS.

    <abstract>Zero code is our mantra for building insurance applications. With OmniChannel Visual Configurator and OmniChannel UI Framework we can build up new applications quickly without any coding intervention, just by means of a visual canvas where we can drag and drop UI components from a catalog and integrate them with existing PAS REST APIs. The result is a working insurance application, built in minutes, automatically deployed and ready to be used from multiple channels (web, mobile, chatbot, voice).</abstract>

Что мне нужно, так это.

Было бы лучше, если бы я мог также хранить имя поля в столбце, например.
