The task_struct structures are stored on one or more lists.  Note the 
list_head types within the structure - each of this is a list that the 
structure is (potentially) a member of.

This is a good explanation of how the kernel's lists work:

I don't know if a generalized printer/parser exists for the kernel 
linked list, but this might be a good way to start exploring your 
project.  There are macros to traverse the lists easily, so it shouldn't 
be too difficult.

Hope that helps.

Cheers,
Dan
