So, I have this JavaScript function:

ME.Utils = {
    RxEmail: new RegExp(/^(("[\w-\s]+")|([\w-]+(?:\.[\w-]+)*)|("[\w-\s]+")([\w-]+(?:\.[\w-]+)*))(@((?:[\w-]+\.)*\w[\w-]{0,66})\.([a-z]{2,6}(?:\.[a-z]{2})?)$)|(@\[?((25[0-5]\.|2[0-4][0-9]\.|1[0-9]{2}\.|[0-9]{1,2}\.))((25[0-5]|2[0-4][0-9]|1[0-9]{2}|[0-9]{1,2})\.){2}(25[0-5]|2[0-4][0-9]|1[0-9]{2}|[0-9]{1,2})\]?$)/i),

    ValidateEmail: function(email) {
        return ME.Utils.RxEmail.test(email);
    },

    GetEmailAddresses: function(text) {
        return text.match(ME.Utils.RxEmail);
    },

    HasEmail: function(text) {
        return ME.Utils.GetEmailAddresses != null;
    }
};

ValidateEmail works very well. However, HasEmail and GetEmailAddresses is not working properly.

GetEmailAdresses always returns null, except for when the string only contains an email address. In this case, GetEmailAdresses returns an array not only containing the email address, but the email address ([email protected]), just the id (test) plus some unidentified etc. etc...

Can you help me figure out what's wrong in my expression?
