Will you need to parse "Hannover 96 2 Schalke 04 1 (Final)"? — Thilo

"Hannover 96 Schalke 04 (Final)" Something like this. But not the extra 2 and 1 after the scores. — Raghunandan

Below is a SSCCE showing how to use regex and groups to extract the data you want.

FYI, although it will work for just the input you provided, this code will scan through input containing multiple results like this, matching all of them in the while loop.

public static void main( String[] args ) {
    String input = "New England 12 Philidelphia 24 (Final)";
    String regex = "([a-zA-Z ]+)\\s+(\\d+)\\s+([a-zA-Z ]+)\\s+(\\d+)\\s+\\((\\w+)\\)";
    Matcher matcher = Pattern.compile( regex ).matcher( input);
    while (matcher.find( )) {
        String team1 = matcher.group(1);
        String score1 = matcher.group(2);
        String team2 = matcher.group(3);
        String score2 = matcher.group(4);
        String result = matcher.group(5);
        System.out.println( team1 + " scored " + score1 + ", " + team2 + " scored " + score2 + ", which was " + result);
    }
}

Output

New England scored 12, Philidelphia scored 24, which was Final

Try this out

^[\D]*\s*\d*\s*[\D]*\s*\d*\s*\([\D]*\)$

Use this:

"(\\w+) (\\d+) (\\w+) (\\d+) \((\\w+)\)"

How can it be "tested"? It doesn't even compile! (hint: this is a java question)

Shiridish Over a year ago

Oh my goodness. Dint see that. Sorry, that was in c#, but this regex should work fine.

I don't have an idea how to extract from the groups in java, so could just give you the regex. Have a look at the solution in THIS to get an idea in using the above expression for extracting values from groups

Raghunandan Over a year ago

i guess u have to add extra \ like "(\\w+) (\\d+) (\\w+) (\\d+) \((\\w+)\)" so that u escape \ in java.

Shiridish Over a year ago

yes to escape a \ or ( we use a \, but do you need to do it in case of \w or \d as well, as you did? I dont think so! Did that work?
