I have file with records as above and I want to find record starting with 'D' and get the next pipe delimited values. And store those in some pojo object.

So tried to first read values by applying pattern but unable to find match.

String pattern = "r'D((?:"(.*?)"))'";

Pattern r = Pattern.compile(pattern); Matcher m = r.matcher(line); 
if (m.find( )) { 
    System.out.println("value1" + m.group(0) ); 
    System.out.println("value2" + m.group(1) ); 
} else {
    System.out.println("No Match"); 
    }
