[jira] Created: (DERBY-4919) Use the built-in XML libraries for generating XML in PlanExporter

Use the built-in XML libraries for generating XML in PlanExporter
-----------------------------------------------------------------

                 Key: DERBY-4919
                 URL: https://issues.apache.org/jira/browse/DERBY-4919
             Project: Derby
          Issue Type: Improvement
          Components: Tools
    Affects Versions: 10.7.1.0
            Reporter: Knut Anders Hatlen
            Priority: Minor


The plan exporter tool creates XML manually. It would be good to make it use the XML libraries that come with the Java platform so that we could be more confident that the XML it produces will be well-formed. The tool already uses these libraries for generating HTML.

The XML libraries are not part of the Foundation Profile API, so on the small device platforms the Xalan jars would have to be on the classpath in order to produce the XML version of the query plan. This is already a requirement on those platforms for generating the HTML version of the plan. All other supported platforms contain the required XML libraries.
