I am trying to read the email_list file and output only email addresses separated by semi-column. But my code goes into a loop.
Can anybody help me in this??
email_file.txt has following records:
Doe, John <john.doe@abc.com>;Smith, Jeff <jeff.smith@abc.com>; lever, dave <dave.lever@abc.com>
Below is my code:
data test;
length text $32767;
infile 'c\email_file.txt' lrecl=32767 dsd dlm='09'x truncover;
input text $;
run;
data t1;
set test;
length tx3 $500;
tx3="";
tx1=text;
do until (length(cats(tx1))=0);
space_position = INDEX(tx1, '<');
slash_position = INDEX(tx1, '>');
space_to_slash = slash_position - space_position;
tx2 = substr(tx1, space_position+1, space_to_slash-1);
tx3=cats(tx3,tx2,";");
tx4=substr(tx1,find(tx1,";")+1);
tx1=tx4;
end;
run;
data want;
i=1;
set have;
do until(scan(text,i,';') eq '');
new=scan(text,i,';');
i+1;
output;
end;
run;
filename x temp; data _null_; file x; input; put _infile_; cards4; Doe, John;Smith, Jeff ; lever, dave ;;;; run; data want; infile x dlm='>' lrecl=32767; input @'<' email : $100. @@; run;
if only the email id has to be retrieved then please try
data want;
i=1;
set have;
do until(scan(text,i,';') eq '');
new=compress(scan(scan(text,i,';'),2,'<'),'>');
i+1;
output;
end;
run;
Looks like you want to take the parts inside of the <>. This code will do that and also take values that only have the email address without the name and so do not have any <>s.
You can scan the original list using ';' as the delimiter and then within each sub-string look for the values between the <> using scan function again, this time using both < and > as the delimiters.
data want;
set test ;
length want $32767 ;
do i=1 to countw(text,';');
want = catx(';',want,scan(scan(text,i,';'),-1,'<>'));
end;
run;
