Merging Attributes in Apache Nifi after a ExtractText (using Regex)

New Contributor

After using the Nifi ExtractText processor to extract matches from the flowfile-content using regex (using multiple capturing mode), you are supplied with a series of numerically ascending attributes. E.G. date, date.0, date.1, date.2, ... representing multiple captures throughout the text.

What I want is a single attribute ${dates}, that contains each of the entries captured. Can anybody help?

(Nifi v1.5.0)
