             Summary: Allow EvaluateXPath to return multiple results if destination is FlowFile content
                 Key: NIFI-5187
                 URL: https://issues.apache.org/jira/browse/NIFI-5187
             Project: Apache NiFi
          Issue Type: Improvement
          Components: Extensions
            Reporter: Matt Burgess


EvaluateXPath currently expects a Nodeset to be returned from the XPath expression if the destination is FlowFile content, but it also requires that the Nodeset only have one element. Since the element is output as a string, it could support Nodesets with multiple elements, using a newline as a delimiter (and perhaps escaping any newlines in the elements' values if necessary), only if the destination was FlowFile content.

This improvement would make it easier to prepare XML for use by a record processor, for example.
