please I am a novice when it comes to regexes, Using search and replace, how can i allow only a-z, A-Z, 0.9 and - on a link, E.g

,ido song/ will be replaced with /

,i'do/ will be replaced with /

i want this to be replace using $1,$2 etc as substitutiion, I am using this in a wp plugin search and replace and i am only restricted to $1,2,3 etc as substitutiion.

i have tried this ([^\w\s]+) to replace with $1 but its still giving me the same output as before.
