Hej Jonas,

That makes sense. So, did you have a look at these pages yet?
for 3D:
http://www.cgal.org/Manual/latest/doc_html/cgal_manual/Triangulation_3_ref/Class_Triangulation_3.html
for 2D:
http://www.cgal.org/Manual/latest/doc_html/cgal_manual/Triangulation_2_ref/Class_Triangulation_2.html
(from your mails I couldn't tell whether you are working in 2D or 3D, 
although I suspect 2D)

On both of these pages at the very end you see that both operator<<() and operator>>() are overloaded in CGAL to act on a triangulation and the format is explicitly explained. Since you already have 
the full triangulation in some format, I'm guessing it shouldn't be to hard too convert that into 'CGAL-formatting', allowing you to directly read the triangulation into CGAL triangulation object 
using the extraction operator, operator>>().

Sincerely,
Jakob
