Question

Here is some sample input:

<210>   DW_AT_name        : (indirect string, offset: 0x55): double
    DW_AT_name        : (indirect string, offset:          


        

Answer 1

Try the next:

public static void main(String[] args) {

    String text = 
    "<210>   DW_AT_name        : (indirect string, offset: 0x55): double\n" + 
    "   DW_AT_name        : (indirect string, offset: 0x24): long int\n" + 
    "   DW_AT_name        : int";

    Pattern pattern = Pattern.compile("^.*DW_AT_NAME.*:\\s*([^:]+)$", 
            Pattern.CASE_INSENSITIVE);

    Scanner sc = new Scanner(text);
    while(sc.hasNextLine()) {
        String line = sc.nextLine();
        Matcher matcher = pattern.matcher(line);
        if (matcher.matches()) {
            System.out.println(matcher.replaceAll("$1"));
        }
    }

}

Output:

double
long int
int
