Hi I have the following 2 type of string which I need to use the same regex for.

string 1 :

2022.08.14 (19h45) - Salernitana 0-1 AS Roma (suppercoppa)

string 2 :

2022.08.14 (19h45) - Salernitana 0-1 AS Roma

I need to use one regex so I can get 3 different groups

Group1: Date
Group2: Team Name 1 (Salernitana)
Group3: Team Name 2 (AS Roma)

What I have tried:

I tried the following regex which is working for string 2 but not for string 1:

([0-9]+\.[0-9]+\.[0-9]+).*- (.*[a-zA-Z]) .*[0-9] ([a-zA-Z]+.*)

Should you have a match with
2022.08.14 (19h45) - AS Roma 0-1 Salernitana

sorry?

Should it work with "2022.08.14 (19h45) - AS Roma 0-1 Salernitana" ?

yes it works for that text but not for the other text, I want it to work for both of them

Solution 1

When I run your regex (in Expresso) against either string I get similar results:
String 1:

1: 2022.08.14
2: Salernitana
3: AS Roma (suppercoppa)

String 2:

2022.08.14
2: Salernitana
3: AS Roma

So ... what am I doing that you aren't? How did you test your string? Have you tried Expresso[^] - it's free, and it examines and generates Regular expressions.

the "(super coppa)" should not be in group 3, the group 3 need to read all characters until '(' or end of line '$', but I cannot do
it :(

So add that to your regex!
In Expresso, look under the expression builder, Groups - you'll see a "match suffix but exclude it" group.

Try this RegEx with groups 1, 2 and 4

([0-9.]{10}).+- ([a-zA-Z]+( [a-zA-Z]+)*).+\d ([a-zA-Z]+( [a-zA-Z]+)*)

Just a few interesting links to help building and debugging RegEx.
Here is a link to RegEx documentation:
perlre - perldoc.perl.org[^]
Here is links to tools to help build RegEx and debug them:
.NET Regex Tester - Regex Storm[^]
Expresso Regular Expression Tool[^]
RegExr: Learn, Build, & Test RegEx[^]
Online regex tester and debugger: PHP, PCRE, Python, Golang and JavaScript[^]
This one show you the RegEx as a nice graph which is really helpful to understand what is doing a RegEx: Debuggex: Online visual regex tester. JavaScript, Python, and PCRE.[^]
This site also show the Regex in a nice graph but can't test what match the RegEx: Regexper[^]
