Regex to split text in multiple lines keeping delimiter with the text .

[lalit007]

how can we split text in multiple lines keeping delimiter with the text .

example string => var str= "2019-12-09 05:43:55 - System Administrator (Additional comments)testing comments2019-12-09 05:43:49 - System Administrator (Additional comments)test";

expected output: 

2019-12-09 05:43:55 - System Administrator (Additional comments)testing comments

2019-12-09 05:43:49 - System Administrator (Additional comments)test

i have tried 'exec' and 'split' methods (given below) to separate the comments but it didn't work out.

var pattern = /(\d{4}[-]\d{2}[-]\d{2}[\s]\d{2}[:]\d{2}[:]\d{2})/g;
var array1 =[];
array1 = pattern.exec(str);

gs.print("exec "+array1[0]);

var array2 = str.split(pattern);

for (var i=0 ; i<=array2.length;i++){
gs.print("split "+array2[i]+"-"+array2[i+1] +" ");
}

is it possible to get expected result?

Try This: 

var str= "2019-12-09 05:43:55 - System Administrator (Additional comments)testing comments2019-12-09 05:43:49 - System Administrator (Additional comments)test";

var pattern = /(\d{4}[-]\d{2}[-]\d{2}[\s]\d{2}[:]\d{2}[:]\d{2})/g;

var array = str.match(pattern);


for (var i=0;i<array.length;i++) {

str = str.replace(array[i], "\n"+array[i]);

}

gs.info(str);
