This will perform a regular expression search/replace on a string in your template.

{% load replace %} {{ mystring|replace:"/l(u+)pin/m\1gen" }}

If: mystring = 'lupin, luuuuuupin, and luuuuuuuuuuuuupin are lè pwn' then it will return: mugen, muuuuuugen, and muuuuuuuuuuuuugen are lè pwn

The argument is in the following format:

[delim char]regexp search[delim char]regexp replace
