How to use sed command to match strings starting with &# in my html file and replace it with space ?

  • Example: &#192
  • Result: space
  • Should be completely replaced by space

It should work for all the HTML codes with three or 4 digits trailing &#.

Basically HTML codes: http://webdesign.about.com/library/bl_htmlcodes.html
