I've exported a "book" of .indd format files (each of which a chapter) to an epub file. The process creates an OEBPS folder containing the .indd files in xhtml format and a toc.ncx file which supposedly contains the information enabling Adobe Digital Editions to display a list of selectable chapters in its left-most column. However, I had to change many of the tags in those xhtml files using Dreamweaver. After those changes some of the chapters are no longer incorporated into the .epub file when it's viewed using Digital Editions (even though the xhtml for the chapters that view are identical -except for chapter names- to the xhtml for chapters that don't view). Curiously, the chapter titles are present in the left-most column but clicking on them produces no result. My guess is that after changes were made to the xhtml files (using Dreamweaver) corresponding changes must be made to the toc.ncx file. However, I can't find an application that will open it. Does anyone know how to open the toc.ncx file and whether, once opened, adjustments are possible which would solve the above described problem?
