my list al is as below:

al
[[1]]
[1] 2 3
[[2]]
[1] 5
[[3]]
[1] 7
and I check the second component, its element is 5, then I remove this, now
my al is:
al[[2]][al[[2]]!=5]->al[[2]]
al
[[1]]
[1] 2 3
[[2]]
numeric(0)
[[3]]
[1] 7
The Question is, how I can get the new list without the second component,
that is :
alwanted
[[1]]
[1] 2 3
[[2]]
[1] 7
Thank you for your help!!!
