             Summary: TransformXml crashes creating CDATA (Saxon issue?)
                 Key: NIFI-5144
                 URL: https://issues.apache.org/jira/browse/NIFI-5144
             Project: Apache NiFi
          Issue Type: Bug
    Affects Versions: 1.6.0
            Reporter: Chris Green


Hi all,

I've not submitted a Jira issue before, apologies if this is in the wrong place.

 

I'm attempting to transform XML containing CDATA sections, into another structure but keeping the CDATA tags. A 3rd party XML transformer confirms the XSLT I've got transforms the XML successfully, using xsl:output to specify which output elements to create as CDATA.

Using the same XML and XSLT in NiFi 1.6.0 causes the following exception:

{{java.lang.IllegalArgumentException: Value of {cdata-section-elements} must be a list of QNames in '\{uri}local' notation}}

The stack trace (below) mentions the Saxon library, which I've searched for along with the exception and found the bug detailed [here|https://saxonica.plan.io/issues/2795].

NiFi 1.6.0 appears to be bundled with Saxon-HE-9.6.0-5.jar, which is a version from before the bug above was fixed (if they are related).

 

Full stack trace of the issue:
