Enter country information based on email address

Epid — Mon, 07 Sep 2020 08:23:58 GMT

Dear SAS users,

I have a list 32K articles and want to have first author's country based on their domain of email information.

For example,

email	Country
xxxx@lumc.nl	Netherlands
xxxx@hku.hk	Hong Kong

Am I able to use any SAS to have column "Country" from "email" column?

Thanks for your suggestions in advance,

BR,

Epi

Yes within some limits:

proc format lib=work;
    value $country
     'nl' = 'Netherland'
     'hk' = 'Hong Kong'
    ....
; run;
data want;
 set have;
       code = scan(email,-1,'.');
      country = putc(code,$country.);
run;

Pay attention that in some emails there may be no country code,

as in xxxxxx@gmail.com or xxxxxx@yahoo.com etc.

Thanks Shmuel, So, I have to list all countries like 'nl'='Netherlands'.

What if there are more than one email addresses in one cell? I only need to use the first email address. Please advise me how I can deal in that case.

Thanks again,

1) Create the format with as many countries as you can add a line with

proc format lib=work;
    value $country
     'nl' = 'Netherland'
     'hk' = 'Hong Kong'
    ....
    other = "*unKnown*"   /* choose any text you prefer */
; run;

2) In case there are more than one email, you need to select which is preferred or add a country per email (email1-country1 email2-country2 ...)

If you post a sample of your data in a form of a data step with input from datalines. I'll be able

to propose some available code to deal with.

I am sure that icann (or maybe mozilla) has a usable list that you can import and use to create the format.

Dear Shmuel,

Sorry for my delayed response. Thanks a lot.

I have 32K data like this. I wanna add one column with country name based on domain of first email address. If domain is like .edu; .com etc then leave as empty.

Thanks again,
