find strings between (),[],{},' '," " and split them in new variables

Posted 03-18-2019 12:10 PM (1530 views)

Dear all,

 

How can I find all strings between (),[],and {} (such as <BR>, [FONT],{BODY},'A',"JUICE") and split them in a new variable?

 

Especially, for the 

'JUICE<BR>apple<footer>',I expect to add a blank between 'JUICE' and 'apple'

 

by using the following code,


data have ;
  infile datalines truncover;
  input name $100.;
  datalines;JUICE<BR>apple[footer] 
juice <BR> apple 
juice<BODY> 'apple' 
juice{BODY} apple 
[BR]juice apple
<figure> "juice" LTD
 ;
run;

data want1;
   set have;
   RegExID = prxparse('/<\w*>/');
   start=1;
   call prxnext(RegExID, start, length(name), name, pos, length);
      do while (pos > 0);
         html = substr(name, pos, length);
         newname=prxchange('s/<\w*>//', -1, name);
         output;
         call prxnext(RegExID, start, length(name), name, pos, length);
      end;
   keep name html newname;
run;

I get 

namehtmlnewname
JUICE<BR>apple<footer><BR>JUICEapple
JUICE<BR>apple<footer><footer>JUICEapple

 

however, I expect to add a blank between 'JUICE' and 'apple'

namehtmlnewname  
JUICE<BR>apple<footer>BRJUICE apple
JUICE<BR>apple<footer>footerJUICE apple

 

 

 

 

Could you please give me some suggestions about this?

thanks in advance.

Ah, I see what the problem is. The old Quotes Within Quotes problem 🙂

 

This

 

data have ;
  infile datalines truncover;
  input name $100.;
  datalines;
JUICE<BR>apple[footer] 
juice <BR> apple 
juice<BODY> 'apple'
<figure> "juice" LTD
;

data want;
   format name html newname;
   set have;
   RegExID = prxparse('/<\w*>|\[\w*\]|\(\w*\)|"\w*"|''\w*''/');
   start=1;
   call prxnext(RegExID, start, length(name), name, pos, length);
   newname=prxchange('s/<\w*>|\[\w*\]|\(\w*\)|"\w*"|''\w*''/ /', -1, name);
      do while (pos > 0);
         html = substr(name, pos+1, length-2);
         output;
         call prxnext(RegExID, start, length(name), name, pos, length);
      end;
   keep name html newname;
run;

proc print data=want;
run;

gives you

Just made a very small change to your program in the PRXCHANGE Function. See if this does the trick

 

data have ;
  infile datalines truncover;
  input name $100.;
  datalines;JUICE<BR>apple[footer] 
juice <BR> apple 
juice<BODY> 'apple' 
juice{BODY} apple 
[BR]juice apple
<figure> "juice" LTD ;
run;
data want1;
   set have;
   RegExID = prxparse('/<\w*>/');
   start=1;
   call prxnext(RegExID, start, length(name), name, pos, length);
      do while (pos > 0);
         html = substr(name, pos, length);
         newname=prxchange('s/<\w*>/ /', -1, name);
         output;
         call prxnext(RegExID, start, length(name), name, pos, length);
      end;
   keep name html newname;
run;

thanks draycut,

 

but I get 

namehtmlnewname
JUICE<BR>apple[footer]<BR>JUICE apple[footer]
juice <BR> apple<BR>juice apple
juice<BODY> 'apple'<BODY>juice 'apple'
<figure> "juice" LTD<figure>"juice" LTD

besides, 

 

I cannot get the expected result by following code,

data want1;
   set have;
   RegExID = prxparse('/<\w*>|[\w*]|{\w*}|'\w*'|"\w*"/');
   start=1;
   call prxnext(RegExID, start, length(name), name, pos, length);
      do while (pos > 0);
         html = substr(name, pos, length);
         newname=prxchange('s/<\w*>|[\w*]|{\w*}|'\w*'|"\w*"/ /', -1, name);
         output;
         call prxnext(RegExID, start, length(name), name, pos, length);
      end;
   keep name html newname;
run

Hello @PeterClemmensen 

 

I have a new question during the process.

the 

HARDY(FRNS.)'A'

cannot be processed by the code 

I expect to get 

nameCOMPANY_NAME_inBCOMPANY_NAME_noB
HARDY(FRNS.)'A'FRNS.HARDY
HARDY(FRNS.)'A'AHARDY

However, I only get 

nameCOMPANY_NAME_inBCOMPANY_NAME_noB
HARDY(FRNS.)'A'AHARDY(FRNS.)

 

Could you please give me some suggestions?
