split the value when they are included in the ( ),[ ],{ },' '," ", separated by blank and count freq

Alexxxxxxx — Thu, 04 Apr 2019 00:08:37 GMT

Dear all,

how can I split the value when they are included in the ( ),[ ],{ },' '," ", or separated by blank, and then count the frequency of their appearance?

for example,

for table A

no	name
1	juice<BR>a@pple[footer]
2	juice <BR> apple
3	juice<BODY> 'apple'
4	juice{BODY} apple
5	[BR]juice appl'e
6	<figure> "juice" LTD

I expect to get table b

no	name	new_name	count the frequency
1	juice<BR>a@pple[footer]	juice	6
1	juice<BR>a@pple[footer]	BR	3
1	juice<BR>a@pple[footer]	a@pple	1
1	juice<BR>a@pple[footer]	footer	1
2	juice <BR> apple	juice	6
2	juice <BR> apple	BR	3
2	juice <BR> apple	apple	2
3	juice<BODY> 'apple'	juice	6
3	juice<BODY> 'apple'	BODY	2
3	juice<BODY> 'apple'	apple	2
4	juice{BODY} CO.LTD	juice	6
4	juice{BODY} CO.LTD	BODY	2
4	juice{BODY} CO.LTD	CO.LTD	1
5	[BR]juice appl'e	BR	3
5	[BR]juice appl'e	juice	6
5	[BR]juice appl'e	appl'e	1
6	<figure> "juice" LTD	figure	1
6	<figure> "juice" LTD	juice	6
6	<figure> "juice" LTD	LTD	1

'count the frequency' count the frequency of 'new_name’ appearance in the total 'new_name' variables.

Could you please give me some suggestions about this?

thanks in advance.

You already have the split part from previous replies.

Now you must:

- count

- merge the counts and the splits

Please try and report.

Dear @ChrisNZ

thanks. yes, I can split the variable based on brackets etc. by the following code,

Data step9.Patstat_gb_hrm_Step3;
Set step9.Patstat_gb_hrm_Step23;
Run;

%MACRO CompnayNameM(no=,Company_name=);

data step9.Patstat_gb_hrm_Step3;
   set step9.Patstat_gb_hrm_Step3;
   RegExID = prxparse('/<.*>|\[.*\]|\(.*\)|".*"|''.*''/');
   start=1;
   stop=length(&COMPANY_NAME._Step23);
   call prxnext(RegExID, start, stop, &COMPANY_NAME._Step23, pos, length);
      do while (pos > 0);
         &COMPANY_NAME._inB = substr(&COMPANY_NAME._Step23, pos+1, length-2);
         &COMPANY_NAME._noB = prxchange('s/<.*>|\[.*\]|\(.*\)|".*"|''.*''/ /', -1, &COMPANY_NAME._Step23);
         call prxnext(RegExID, start, stop, &COMPANY_NAME._Step23, pos, length);
      end;
	  drop RegExID pos length start stop;
run;

proc sql;
create table PATSTAT&no. as
select distinct
&COMPANY_NAME.,
&COMPANY_NAME._Step23,
&COMPANY_NAME._inB,
&COMPANY_NAME._noB
from step9.Patstat_gb_hrm_Step3
where &COMPANY_NAME._inB ne ''
;
quit;

%MEND CompnayNameM;

%CompnayNameM(no=1,Company_name=HRM_L2)
%CompnayNameM(no=2,Company_name=PERSON_NAME)
run;

However, I do not know how to separate them based on the blank. Could you please give me some suggestion about this part?

This way to split is more generic and easier to manage:

data HAVE;
input NO NAME &:$100.;
infile datalines  missover;
datalines;
1 juice<BR>a@pple[footer] 
2 juice <BR> apple 
3 juice<BODY> 'apple' 
4 juice{BODY} apple 
5 [BR]juice appl'e
6 <figure> "juice" LTD 
run;

data WANT;
  set HAVE;
  length PAIR MATCH_PAIR MATCH_PAIRS $200 WORD $20;
  retain REGEX;
  array PAIRS [12] $1 _temporary_ ( '['  ']'  '{'  '}'  '<'  '>'  '"'  '"'  "'"  "'"  '('  ')' ) ;
  if _N_=1 then do;
    do I=1 to 12 by 2;
      MATCH_PAIR  = catt('\', PAIRS[I], '(.*)\', PAIRS[I+1]);
      MATCH_PAIRS = catx('|', MATCH_PAIRS, MATCH_PAIR);
    end;
    REGEX = prxparse(catt('s/', MATCH_PAIRS, '/ $1$2$3$4$5$6 /'));
  end;
  NAME1=prxchange(REGEX, -1, NAME);
  do I=1 to countw(NAME1,' ');
    WORD=scan(NAME1, I);
    output;
  end;
  keep NO WORD;
run;

NO	WORD
1	juice
1	BR
1	a@pple
1	footer
2	juice
2	BR
2	apple
3	juice
3	BODY
3	apple
4	juice
4	BODY
4	apple
5	BR
5	juice
5	appl'e
6	figure
6	juice
6	LTD

How important is it to treat this strange value as a single word and not two?

appl'e

If you don't really need to match the various brackets you can just treat them all as delimiters.

data want ;
 set have ;
 word=name;
 do word_no=1 by 1 until(word=' ');
   word =scan(name,word_no,' []{}<>"''');
   if word_no=1 or word ne ' ' then output;
 end;
run;

The FREQ Procedure

                                   Cumulative    Cumulative
word      Frequency     Percent     Frequency      Percent
-----------------------------------------------------------
BODY             2       10.00             2        10.00
BR               3       15.00             5        25.00
LTD              1        5.00             6        30.00
a@pple           1        5.00             7        35.00
appl             1        5.00             8        40.00
apple            3       15.00            11        55.00
e                1        5.00            12        60.00
figure           1        5.00            13        65.00
footer           1        5.00            14        70.00
juice            6       30.00            20       100.00

Dear @ChrisNZ

I really appreciate your help, which works very well. however, I face a problem during the process.

I find some value which includes '&' ( for example, 'SWAN JOHN & SONS', 'SMITH & NEPHEW NEW') are not been processed by the code. and I expect to treat it as a blank.

for example,

no	name
1	SWAN JOHN & SONS
1	SMITH & NEPHEW NEW

no	name	new_name
1	SWAN JOHN & SONS	SWAN
1	SWAN JOHN & SONS	JOHN
1	SWAN JOHN & SONS	SONS
2	SMITH & NEPHEW NEW	SMITH
2	SMITH & NEPHEW NEW	NEPHEW
2	SMITH & NEPHEW NEW	NEW

Could you please give me some suggestion about this?

thanks in advance

Odd, it seems to works for me.

Otherwise, just replace string ' & ' with ' ' ?

Dear @ChrisNZ

thanks for your help.

may I ask one more question, please?

how can I split the variable include '.'?

for example,

for 'M & L PROPERTY & ASS.PLC.'

I get

M & L PROPERTY & ASS.PLC.	M
M & L PROPERTY & ASS.PLC.	L
M & L PROPERTY & ASS.PLC.	PROPERTY
M & L PROPERTY & ASS.PLC.	ASS
M & L PROPERTY & ASS.PLC.	PLC

however, I expect to get

M & L PROPERTY & ASS.PLC.	M
M & L PROPERTY & ASS.PLC.	L
M & L PROPERTY & ASS.PLC.	PROPERTY
M & L PROPERTY & ASS.PLC.	ASS.PLC.

Add a space as the third parameter of the scan function.
