Class EpubNavigationItem

A single navigation element of the book (typically within the table of contents). Depending on the value of the Type property, it can act either as a header or as a navigation link. Unlike EpubNavigationItemRef, this class contains the HtmlContentFile property which (if it's not null) holds the whole content of the file referenced by this navigation element.
