did the trick.

I would suggest you to use more specific pattern to avoid removing of 
meaningful text due to a lost newline character:

sed -i -e '/^\s*<hr  style[^>]*>\s*$/d'

"." in regexp may be a source of surprises (or catastrophic backtracking 
in more complex regexps)

printf 'A <br>b<br>c\n' | sed -e 's/<.*>/\n/'
A
c

printf 'A <br>b<br>c\n' | sed -e 's/<.[^>]>/\n/g'
A
b
c
