Can someone please explain sed -n '/^$/!{s/<[^>]*>//g;p;}' filename

I came across this sed expression, and it does exactly what I want.
However I haven't got the faintest clue how it does it and thus do not feel capable of using it.

Can someone please explain how this expression works?
(I used it to remove html tags in a html file I was converting to text)

sed -n '/^$/!{s/<[^>]*>//g;p;}' filename


The more detail the more I love you :-)
Thanks heaps,
