More Regular Expressions: Using Groups to Process Text
The use of classes and grouping within regular expressions allows us to fine-tune how we manipulate and reference our text. Capturing groups, in particular, provide us the opportunity to take parts of our match and use them not only in the expression itself but within our greater code or command. In this learning activity, it is necessary to use groups to retrieve the needed parts of the expression, then process that output so humans can understand and make use of the data.
