is this what you want?
find the "----------" line and skip it
fine the 1st line after it and skip it
find the 2nd line after it and print it
skip all other lines
use nawk
BEGIN { cnt = 0 ; }
/.*----------.*/ { cnt = 1; next; }
cnt == 1 { cnt ++; next; }
cnt == 2 { print; cnt ++; } # print 2nd line past "----"
# ignore all other lines
