johngg has given a solution, but it may leave you wondering what is going on somewhat. The magic is a look behind assertion (the (?<=...) bit). It matches the given match condition (which must be a fixed length). It makes sure that the stuff matches, but the matched stuff is not part of the string that will be replaced. See perlretut and perlre for regex documentation.
