Regex multiple line breaks

I want to substitute the value of HTML <br> tag with 2 newlines. i.e what i want to is 

$string=~s/br>/\n\n/s;

but somehow it doesn't work. Whereas it works fine for a single new line. i.e. if i do this:

$string=~s/br>/\n/s;

it works fine. What am I doing wrong?

If you're talking about vim's substitute command then you probably want to use \r in the replacement string instead of \n. In this context vim treats \n as NULL, not newline.

Relevant snippet from :help sub-replace-special:

<CR>    split line in two at this point
        (Type the <CR> as CTRL-V <Enter>)          *s<CR>*
\r      idem                                       *s/\r*
\<CR>   insert a carriage-return (CTRL-M)
        (Type the <CR> as CTRL-V <Enter>)          *s/\<CR>*
\n      insert a <NL> (<NUL> in the file)
