Pattern.DOTALL

Enables dotall mode. In dotall mode, the expression . matches any character, including a line terminator. By default this expression does not match line terminators.

For Example, address is spawned into multiple lines.

String data = "Address\n" +

"Country: India\n" +

"State: AP\n" +

"City: Guntur\n" +

"Village: Ongole" +

"mailId: 12345676@abc.com";

Now I want to extract upto the field city. Below statements do that.

static Pattern addressPattern = Pattern.compile("(.*)Village:", Pattern.DOTALL);

matcher = addressPattern.matcher(data);

import java.util.regex.*;

public class RegExHarness {
    static Pattern addressPattern = Pattern.compile("(.*)Village:", Pattern.DOTALL);
    static Matcher matcher; 
          
    public static void main(String[] args) {
        String data = "Address\n" +
                    "Country: India\n" +
                    "State: AP\n" +
                    "City: Guntur\n" +
                    "Village: Ongole" +
                    "mailId: 12345676@abc.com";

        RegExHarness obj = new RegExHarness();
 
        System.out.println(data + "\n");

        matcher = addressPattern.matcher(data);
        
        while (matcher.find()) {
            System.out.println(matcher.group(1));
 }
    }
}

Output

Address
Country: India
State: AP
City: Guntur
Village: OngolemailId: 12345676@abc.com

Address
Country: India
State: AP
City: Guntur
