Removing text from specific string

pappusrini — Thu, 11 Jul 2024 03:46:23 GMT

Good Evening, Please advise what is the best way to remove certain text in a string in dataset.

Example: Assignment was sent to John Smith with the reason and status as Pending

Assignment was sent to Peter Smith with the reason and status as Complete.

Output I'm looking for is:

Assignment was sent to John Smith

Assignment was sent to Peter Smith

I want to remove all the text that appears after the name (John smith, Peter Smith) in the above examples.

Thank you

You need to post more examples and rules you are taking account of.

data have;
input x $80.;
cards;
Assignment was sent to John Smith with the reason and status as Pending
Assignment was sent to Peter Smith with the reason and status as Complete.
;
data want;
 set have;
 pid=prxparse('/[A-Z][a-z]+\s+[A-Z][a-z]+/');
 if prxmatch(pid,x) then do;
   call prxsubstr(pid,x,p,l);
   want=substr(x,1,p+l);
 end;
 drop pid p l;
run;

Since we don't know how many words make up the name, it's easier to use with as the marker.

data HAVE;
  input WORDS $80.;
cards;
Assignment was sent to John Smith with the reason and status as Pending
Assignment was sent to Peter Smith with the reason and status as Complete.
run;
data WANT;
  set HAVE;
  WORDS2 = substr(WORDS, 1, index(WORDS, ' with'));
run;
