Simple Transformation - XML to Internal Table Error

Question

I have a webservice call that returns XML.  I need to transform a portion of the response to an internal table, but my simple transformation is not working with loop processing.  I have read through most posts regarding the topic but they're either too old or related to serialization.  There aren't any exceptions thrown, but I don't get any data in the internal table (PAPERWORK root).  Below are some code snippets.  Any ideas on the problem with the XSLT template?  Thanks.
Sample XML:
<?xml version="1.0" encoding="utf-8" ?>
<PrintVersionDataSet>
<Result>
<ReturnCode>W</ReturnCode>
<ReturnMessage>There are reports with later version(s)</ReturnMessage>
</Result>
<Paperwork>
<ReportCode>CVR</ReportCode>
<ReportName>Cover Sheet</ReportName>
<Version>2</Version>
<PrintedDateTime>2009-05-01T09:54:04.1-05:00</PrintedDateTime>
</Paperwork>
<Paperwork>
<ReportCode>SPS</ReportCode>
<ReportName>Sponsor Summary</ReportName>
<Version>2</Version>
<PrintedDateTime>2009-05-01T09:54:04.99-05:00</PrintedDateTime>
</Paperwork>
</PrintVersionDataSet>
XSLT Code:
<?sap.transform simple?>
<tt:transform xmlns:tt="http://www.sap.com/transformation-templates">
  <tt:root name="RESULT"/>
  <tt:root name="PAPERWORK"/>
  <tt:template>
    <PrintVersionDataSet>
      <Result tt:ref="RESULT">
        <ReturnCode>
          <tt:value ref="RETURNCODE"/>
        </ReturnCode>
        <ReturnMessage>
          <tt:value ref="RETURNMESSAGE"/>
        </ReturnMessage>
      </Result>
      <tt:deserialize>
        <tt:loop ref=".PAPERWORK">
          <Paperwork>
            <ReportCode>
              <tt:value ref="REPORTCODE"/>
            </ReportCode>
            <ReportName>
              <tt:value ref="REPORTNAME"/>
            </ReportName>
            <Version>
              <tt:value ref="VERSION"/>
            </Version>
            <PrintedDateTime>
              <tt:value ref="PRINTEDDATETIME"/>
            </PrintedDateTime>
          </Paperwork>
        </tt:loop>
      </tt:deserialize>
    </PrintVersionDataSet>
  </tt:template>
</tt:transform>
ABAP Call to Transform Data:
TRY.
CALL TRANSFORMATION Z_GA_PAPERWORK_VERS_WEBSVC
      SOURCE XML LS_RESPONSE-VERIFY_PRINT_VERSION_RESULT
      RESULT RESULT     = LS_RESULT
             PAPERWORK  = LT_PAPERWORK.
    CATCH CX_ROOT INTO ROOT_EXCEPTION.
      CALL METHOD ROOT_EXCEPTION->IF_MESSAGE~GET_TEXT
        RECEIVING
          RESULT = LV_MESSAGE.
  ENDTRY.

Answer 1

Upon further inspection and testing with a simple file and program, I can see that the XML structure isn't quite correct for the loop process.  There needs to be a single <PAPERWORK> node, instead of one for each table line in the file.  This should allow the loop to execute properly after a slight adjustment to the XSLT template.
