The regular expression you are looking for is

^[a-z A-Z0-9\/\\.'"]+$

Remember if you are using PHP you need to use \ to escape the backslashes and the quotation mark you use to encapsulate the string.

In PHP using preg_match it should look like this:

preg_match("/^[a-z A-Z0-9\\/\\\\.'\"]+$/",$value);

This is a good place to find the regular expressions you might want to use.
