Mike Thomsen resolved NIFI-4214.
--------------------------------
Resolution: Won't Do
There's room to expand the capabilities of GetHtmlElement, but adding JSoup as
a dependency of the expression language module would bloat up the code base
considerably for a feature that's not relevant to a strong majority of NiFi
users.
> Support html element extraction based on CSS Selector in Nifi Expression
> Language

> Key: NIFI-4214
> URL: https://issues.apache.org/jira/browse/NIFI-4214
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Core Framework
> Reporter: Anil
> Priority: Major
>
> Using GetHtmlElement processor, It seems I can extract only one HTML element
> from the html flow file.
> I would like to know if there is a way to extract multiple html elements from
> a single html flow file (or from flowfile attribute).
> It would have been if HTML element extraction is implemented in the Nifi
> Expression language. something like
> {attributeName:getHtmlElement(CSSSelector)}
