How to keep part of the markup in the field as is when unmarshaling an xml document?

Question

Java

I struggle with the task for the second week. There is a document

<catalog>
 <books>
     ...........постоянно меняется  структура
 </books>
 <address>Павлова 45</address>
</catalog>

The books element can have a unique and unrepeatable structure.
Created a class

@XmlRootElement
    @Data
    @XmlAccessorType(XmlAccessType.NONE)
    @ToString
    static class Catalog{
        @XmlElement(name = "books")
        protected String books;
        @XmlElement(name = "address")
        protected String address;
    }

How to make protected String bookspure xml get into the property during mashaling and get the original xml back when unmarshaling?
