Bash: Read a Text till end and split it on basis of a word

Question

I have a text like

RECORD = ijj%%% klfklk @ ; kjkjkdjjd 333 ; [email protected] ; END ijj%%% klfklk @ ; kjkjkdjjd 333 ; 
[email protected] ; END kjkjlsj ; popo ; END

I want to split it up in 3 sentences. The splitting should be done on basis of reading till start till 'END' is encountered, then reading till next 'END' is encountered, and so on till end of the text

split 1 = ijj%%% klfklk @ ; kjkjkdjjd 333 ; [email protected] ;
split 2 = ijj%%% klfklk @ ; kjkjkdjjd 333 ; [email protected] ;
split 3 = kjkjlsj ; popo ;

Code I used is not able to utilize END . Can you please suggest ?

do
echo "$RECORD" | while read line
#Further processing on each of the split sentences

email=$(echo "$line" | awk -F ';' '{print $1}')
subject=$(echo "$line" | awk -F ';' '{print $2}')
body=$(echo "$line" | awk -F ';' '{print $3}')

echo "$body" | mail -s "$subject"  '[email protected]';
#Further processing on each of the split sentences

done
fi

Consider:

$ s="ijj%%% klfklk @ ; kjkjkdjjd 333 ; [email protected] ; END ijj%%% klfklk @ ; kjkjkdjjd 333 ; 
[email protected] ; END kjkjlsj ; popo ; END" 

$ echo "$s" | tr -d '\n' | awk 'BEGIN{RS=" END ?"}1'
ijj%%% klfklk @ ; kjkjkdjjd 333 ; [email protected] ; 
ijj%%% klfklk @ ; kjkjkdjjd 333 ; [email protected] ; 
kjkjlsj ; popo ;

Turning a string delimited by ' END ' into a string delimited by \n can then be used in a bash loop for whatever you need to do to those substrings:

cnt=1
while read -r line; do
    printf "Line %s: %s\n" "$cnt" "'$line'"
    (( cnt++ ))
done <<<$(echo "$s" | tr -d '\n' | awk 'BEGIN{RS=" END ?"}1')

Prints:

Line 1: 'ijj%%% klfklk @ ; kjkjkdjjd 333 ; [email protected] ;'
Line 2: 'ijj%%% klfklk @ ; kjkjkdjjd 333 ; [email protected] ;'
Line 3: 'kjkjlsj ; popo ;'

If you want pure Bash, you could do:

delimit=" END "
s="${s//$'\n'}"
ss=$s$delimit
array=();
while [[ $ss ]]; do
    array+=( "${ss%%"$delimit"*}" );
    ss=${ss#*"$delimit"};
done;
