Joey Frazee commented on NIFI-2072:
-----------------------------------
[~pvillard] Yeah, I honestly just assumed that would have been there in the
Pattern and/or Matcher. I do want to ask, though, from a usability perspective,
if getting a bit nasty might be justified here?
> Support named captures in ExtractText

> Project: Apache NiFi
> Issue Type: Improvement
> Reporter: Joey Frazee
>
> 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.
