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

from django import template
register = template.Library()

@register.filter
def replace ( string, args ): 
    search  = args.split(args[0])[1]
    replace = args.split(args[0])[2]

    return re.sub( search, replace, string )
