Pierre Villard commented on NIFI-2072: -------------------------------------- [~jfrazee] I was looking at this JIRA and I agree that it would be a great addition. However it seems this is not possible to get the group names from the Pattern expression unless if we are going a bit nasty... http://stackoverflow.com/questions/15588903/get-group-names-in-java-regex > Support named captures in ExtractText > ------------------------------------- > > Key: NIFI-2072 > URL: https://issues.apache.org/jira/browse/NIFI-2072 > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
