[jira] [Created] (NIFI-4190) Expression Language support in EvaluateXPath

Claudiu Stanciu created NIFI-4190:
-------------------------------------

             Summary: Expression Language support in EvaluateXPath
                 Key: NIFI-4190
                 URL: https://issues.apache.org/jira/browse/NIFI-4190
             Project: Apache NiFi
          Issue Type: Improvement
          Components: Extensions
    Affects Versions: 1.3.0
            Reporter: Claudiu Stanciu


As a user, I would like support for Expression Language in the EvaluateXPath processor.

This would be a nice modification as it would allow passing of XPaths from attributes or content, and would permit more generic flows/templates.

As discussed in http://apache-nifi-developer-list.39713.n7.nabble.com/Expression-language-support-in-EvaluateXPath-td16441.html, ideally we want to keep the actual performances for the case where we don't use expression language, and we compile expressions at trigger time only where expression languages are used.
