pulling data from a list with mapcar

I have a list of lists and I want to pull out all of the 7th embedded list
entries to make one list. Is there a way to do this with mapcar? I am
already using it to pull the first entries like this:
(mapcar 'car data-list)
and the second like this:
(mapcar 'cdr data-list)
etc. I might be able to use a foreach statement with nth 7 or something but
i want to play with mapcar

thanks,
kemp

 

If you are saying your original data is ...

(setq lst
'(
("1" "2" "3" "4" "5" "6" "7" "8")
("1" "2" "3" "4" "5" "6" "7" "8")
("1" "2" "3" "4" "5" "6" "7" "8")
)
)

(mapcar
'(lambda (x) (nth 6 x))
lst
)

Should do it.

 

Nice - exactly what I wanted. I tried something similar but the way I tried
to format the lambda was all screwed up, now that I can see how it's really
done I should be good.

Thanks a bunch Michael.
