Вопрос по html, xml – Преобразование HTML в XML

14

У меня есть сотни файлов HTML, которые должны быть преобразованы в XML. Мы используем этот HTML-код для обслуживания контента для приложений, но теперь мы должны использовать этот контент как XML.

HTML-файлы содержат теги, таблицы, теги div, изображения, теги p, b или strong, и т. Д.

Я гуглил и нашел некоторые приложения, но пока не смог достичь.

Не могли бы вы предложить способ преобразования содержимого этих файлов в XML?
