The results of capturing groups [code]()[/code] can be retrieved by passing the group number to the various methods in [RegExMatch]. Group 0 is the default and will always refer to the entire pattern. In the above example, calling [code]result.get_string(1)[/code] would give you [code]0123[/code].
This version of RegEx also supports named capturing groups, and the names can be used to retrieve the results. If two or more groups have the same name, the name would only refer to the first one with a match.

If you need to process multiple results, [method search_all] generates a list of all non-overlapping results. This can be combined with a [code]for[/code] loop for convenience.
