Subject [jira] [Comment Edited] (NIFI-2072) Support named captures in ExtractText
Date Mon, 06 Jul 2020 07:21:00 GMT

-------------------------------------------------------------

Is it really necessary to _enable_ named capture group rather than just use them? If I don't
want a named capture group, I suppose I am just not going to name them, opting instead for
enumerated ones.

> ExtractText currently captures and creates attributes using numeric indices (e.g, attribute.name.0,
attribute.name.1, etc.) whether or not the capture groups are named, i.e., patterns like (?<name>\w+).
> In addition to being more faithful to the provided regexes, named captures could help
simplify data flows because you wouldn't have to add superfluous UpdateAttribute steps which
are just renaming the indexed captures to more interpretable names.
