Hi,

I want to subset string between words 'user/utilisateur' and 'du/in' . Considering English and French both.

I have variable 'Description' with following values:

DECSRIPTION:

Assigned to user Marie-Helene Adams in group CAS

Assigned to user Jeff Mills in group National Personal Lines Auto 3

Assigned to user Wendy Taylor-Wu in group NRU Auto/Casualty

What i want - variable Name with value:

Ali Khan

Marie-Helene Adams

Jeff Mills

Wendy Taylor-Wu

Laurence A. Weinstein

Thank you!

Here is one way:

data want (drop=start end);
  set have;
   if findw(DECSRIPTION,'user') then start=
    findw(DECSRIPTION,'user') +5;
   else start=findw(DECSRIPTION,'utilisateur') +12;
  end=max(findw(DECSRIPTION,'du'),findw(DECSRIPTION,'in')) -1;
  name=substr(DECSRIPTION,start,end-start);
run;

If all your data is this structured, use INDEXW to find the location of the words and that will give you the positions of the string you want to extract. Make sure to either upper case or lower case the comparisons.

data have;
input x $80.;
s=prxmatch('/utilisateur|user/',x);
e=prxmatch('/du groupe|in group/',x);
temp=substr(x,s,e-s);
want=substr(temp,findc(temp,' '));
drop s e temp;
