Share at Facebook

There are several ways to obtain the matched groups from a string using REGEX. One of those is using the scan() function. Here is the example. In this example, its capturing all the words from the string.


string = "get all the mached groups from a string by regex";
matches = string.scan(/(\w+)/);
matches.each{|word|
puts word[0];
}
