Vi / Vim single optional character in a regular expression

I'm doing a search and replace so I want to add a character return after all the paragraph tags so that the code is easier to deal with in vim.

.,$s/<p>/&\r/gc
but I also want it to do this for the closing tags as well.  I heard the ? is sometimes used for a single optional character but I still haven't figured out how to find deal with a single optional character.

I tried this:
.,$s/<?p>/&\r/gc
and this
.,$s/<.?p>/&\r/gc
