converting file paths characters

[tagdigital]

I know this is probably a really dumb questions but does anyone know of any easy way to convert string1 (below) into string2 and back again ???

var string1 = "0|/_Production/";
var string2 = "0:\_Production\";

Thanks

so you want string1 to equal string2 and string2 to equal string1?
