------------------------------------

             Summary: Support XSLT scripts in CXF Transformation feature
                 Key: CXF-4582
                 URL: https://issues.apache.org/jira/browse/CXF-4582
             Project: CXF
          Issue Type: Improvement
          Components: Core
            Reporter: Andrei Shakirin
            Priority: Minor


Hi,

Actually CXF Transformation feature covers 99% of user needs:
1) changing input and output element names and namespaces
2) appending new input and output elements
3) replacing text content
4) dropping output and input elements
5) converting attributes to elements

Anyway I see some advanced use cases not supported by CXF Transformation feature, like:
1) replace/rename attributes;
2) replace/remove attributes values
3) process lists
etc.

My proposal is to add property for Transformation feature that specified XSLT transformation
script to support such advanced use cases.
It will look like:
<bean id="transformFeature" class="org.apache.cxf.feature.StaxTransformFeature">
  <property name="inXSLT" value="/org/test/my-in.xslt"/>
  <property name="outXSLT" value="/org/test/my-out.xslt"/>
</bean> 

XSLT engine Xalan will probably break the streaming (AFAIK is still load tree into memory,
incremental transformation just do it in optimized parallel way). But for small messages is
still an option and looking forward - probably clean stream oriented processing will be supported
in the future.

I have basic implementation and will provide a patch, if the improvement makes sense.

Regards,
Andrei.
