How to extract rest of the text after a specific word

MrTAL — Fri, 12 May 2023 13:31:14 GMT

Hi, I have a variable called "Customer_Comment " (a string) with free text and I need to extract rest of the comment after specific word.

Word word word word word KEYword word word word word word

Word word KEYword word word word word

Word word word word word

Word word word word word word word word KEYword word word word.

The comments are something like above and what I need is to extract all the text after the key word, if the Keyword exists in the comment, so the result would be like below..

word word word word word.

word word word word.

word word word.

I have tried few functions such as SCAN,FIND,SUBSTR but couldn't get it done, so any help is much appreciated!

Hi, do you have access to Visual Text Analytics? This would be straightforward with LITI syntax in a concept rule. Otherwise you might want to try regular expressions. For example you could use PRXMATCH to match against the pattern then return the remained or the string.

You might try something like this if the data is simple enough:

data want;
set have;
*find pattern location (add 7 to discard keyword);
position = prxmatch('/KEYword/',text) + 7;
*substring remainder of text;
if position gt 7 then out = substr(text,position);
keep text position out;
run;

want=prxchange('s/.*?KEYword(.*)/$1/',-1,have);

as for example in

DATA demo;
   LENGTH have want $100;
   have="Word word word word word KEYword word1 word2 word3 word4 word5";
   want=prxchange('s/.*?KEYword(.*)/$1/',-1,have);
RUN;
