-----------------------------------
Summary: GetHTMLElement removes content from resulting flowfiles
even when destination is attribute
Key: NIFI-4356
URL: https://issues.apache.org/jira/browse/NIFI-4356
Project: Apache NiFi
Issue Type: Bug
Components: Extensions
Affects Versions: 1.3.0
Reporter: Andy LoPresto
As noted in
[StackOverflow|https://stackoverflow.com/questions/46070288/multiple-gethtml-attributes-in-apache-nifi],
{{GetHTMLElement}} processors cannot be chained because the success
relationship clears the flowfile content even if the destination is an
attribute. I propose the logic be changed to the following:
* Destination = content
* Replace the flowfile content for the *success* relationship
* Maintain the content for *original*
* Destination = attribute
* Maintain the content for *success* and *original*
* Add a property descriptor for the attribute name
* Name attributes {{Attribute.1}} as in {{Extract*}} in the event that
multiple elements are matched
