ExtractText resulting multiple attributes

[KhajaAsmath Mohammed <md...@gmail.com>]

Hi,

I am extracting text using the below expression in NIFI and it results in 3
attributes.

Is there a way to get only one attribute?
event_bag
*event_bag.0*
*event_bag.1*

Asmath,

You can set the “Include Capture Group 0” property to false. That will eliminate event_bag.0.
The processor adds a new attribute for each Capture Group specified in the Regex. So you’ll need to change your regular expression to not use Capturing Groups.

For example: (?s)(?:.*)

It probably makes sense to have another property that controls whether or not any non-zero capture groups get added as attributes or not, but currently this is how it will behave.

Thanks
