Regex to find a string after the last colon

Question

Here is some sample input:

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


        

Answer 1

You need no regex for this:

String yourString = "<210>   DW_AT_name        : (indirect string, offset: 0x55): double";
String result;
if (yourString.contains("DW_AT_name")) {
    int lastIndex = yourString.lastIndexOf(":");
    result = yourString.substring(lastIndex + 1).trim();
} else {
    result = "ERROR"; // or handle this however you want
}
System.out.println(result);

Simply find the last : and take everything after that. Then trim it to remove leading and trailing whitespace.

I edited my question, it needs to also check for DW_AT_name. String split wont [sic] do that.

Just use contains, then. (edited answer)
