Replace specific HTML tags using sed and regular expression

In this post I would like to replace all HTML tags in a HTML file with a tag.

# sed -e 's/<embed[^>]*>/<strong>/g' filename.html > newfile.html

And if you would like to remove the tag altogether

# sed -e 's/<embed[^>]*>//g' filename.html > newfile.html

To remove all HTML tags in a file

# sed -e 's/<[^>]*>//g' filename.html > newfile.html

The result file newfile.html is now without any < HTML tags >.
