Fill in Blanks with 'NA'

may0423 — Tue, 27 Dec 2016 04:01:47 GMT

Hello~

I am trying to replace blanks (which were not noted as '.', see attachment, line5, line8-9, line13-14) with 'NA' by if location =' ' then 'NA'; but nothing happened. Please help. Thank you!

You can try missing function:

IF Missing(Location) then Location = 'NA';

run;

There are some unprintable character other than white blank.

data x;
location='      ';output;
location='09'x;output;
location='xxxxxx';output;
run;
data x;
 set x;
 if prxmatch('/^\s+$/',location) then new='NA        ';
  else new=location;
run;

Besides, how could I extract the location between <dt>Location</dt> <dd> and </dd>? (see attachment)

data testlocation;
filename indata url 'http://forums.vwvortex.com/showthread.php?7286873-To-our-readers' lrecl=10000;
infile indata length=len;
input record $varying10000. len;
input @ '<dt>Join Date</dt> <dd>' / location :&$10000. ;
if location = ' ’ then location = ‘NA’;

data order_location;
set work. testlocation;
rank_num=_n_;
run;

I just adapted

 if prxmatch('/^\s+$/',location) then new='NA        ';
  else new=location;

a little bit. It worked! thank you Ksharp.

A picture attachment is not helpful. If we want to mock up code we have to manually type out your data. If you have blank characters besides spaces there's no way to check.

Post as text or a SAS dataset but posting an image is not very useful.
