Hi All,
could you please help me. I have one Variable with two delimiters ( : and , )
Variable |
test1:aaaa,test2:bbbb,test3:ccc |
test2:ddd,test1:ee25,test3:ffffff |
test3:gg,test1:h,test2:jj12 |
I want to extract the Variables test1 to test3 with the Values.
test1 | test2 | test3 |
aaaa | bbbb | ccc |
ee25 | ddd | ffffff |
h | jj12 | gg |
Thanks in advance.
Looks like you have name/value pairs. So generate a data structure that reflects that.
data tall ;
set have ;
do index=1 by 1 until(index>= countw(variable,','));
length name $32 value $200 ;
value = scan(variable,index,'.');
name=scan(value,1,':');
value=scan(value,2,':');
output;
end;
run;
If you want to generate that flattened file then using PROC TRANSPOSE. Let's assume you also have a variable named ID that uniquely identifies the rows of the original dataset.
proc transpose data=tall out=want(drop=_name_);
by id ;
var value;
id name;
run;
The SCAN function allows you to separate "words" using multiple delimiters.
Are the words TEST1 TEST2 TEST3 always present in every row, or could there be other words like TEST4 or GORILLA?
no some times in the variable just test1 and test 3 like that.
Variable
......
test1;ll,test3:p12
There is no words "test2"
but I want to use always the words test1, test2, and test3 the new Variable names

Hi @Beecelal,
You may want to try the "_infile_ trick":
data have;
input variable $50.;
cards;
test1:aaaa,test2:bbbb,test3:ccc
test2:ddd,test1:ee25,test3:ffffff
test3:gg,test1:h,test2:jj12
test1:ll,test3:p12
;
data want(keep=test:);
set have;
infile sasautos(verify.sas);
if _n_=1 then input @;
_infile_=translate(variable,'=',':,');
input @1 (test1-test3)(= :$10.) @@; /* increase length 10 if insufficient */
run;
