Maybe a bug? using DBMS_XMLGen.ctxHandle;

Question

Hi all, I use a Oracle 10g Database, and i don't know if the following is a bug or i have done something wrong.
I am trying:
CREATE OR REPLACE PROCEDURE MAIN.PRUEBA_XML IS
v_xml clob;
v_ctx DBMS_XMLGen.ctxHandle;
doc xmldom.DOMDocument;
BEGIN
DBMS_LOB.CreateTemporary(v_xml,TRUE);
v_ctx := DBMS_XMLQuery.newContext('Select * from TEST');
v_xml := DBMS_XMLGen.GetXML(v_ctx); -- CRASHES HERE ORA 19019
dbms_xslprocessor.clob2file (v_xml, 'TEMP_DIR', 'XSL_TEST.xml');
dbms_lob.freetemporary(v_xml);
END PRUEBA_XML
And it crashes in the line:
v_xml := DBMS_XMLGen.GetXML(v_ctx);
with an ORA 19019 Error,
but the command 'Select * from TEST' is Ok, bacause i tested on Toad.
Can someone tell how to solve this or if maybe it's a bug?

Answer 1

i am doing this:
CREATE OR REPLACE PROCEDURE SIGADMIN.PRUEBA_XML_XSL IS
queryCtx dbms_xmlquery.ctxType;
result CLOB;
BEGIN
queryCtx := dbms_xmlquery.newContext(
'SELECT TEST_COAPI "COAPI"
, TEST_DNAPI "DNAPI"
FROM TEST'
dbms_xmlquery.setRowTag(
queryCtx
, 'MODULO'
dbms_xmlquery.setRowSetTag(
queryCtx
, 'MODULOS'
DBMS_XMLQUERY.setencodingtag (v_queryctx, 'ISO-8859-1');
result := dbms_xmlquery.getXml(queryCtx);
dbms_xmlquery.closeContext(queryCtx);
dbms_xslprocessor.clob2file (result, 'TEMP_DIR', 'PRUEBA_XML_XSL.xml');
dbms_lob.freetemporary(result);
END
And this works fine for me,
but i have another thing to solve, and that's, ¿how to "delete" the num attribute?,
any idea would be appreciated :)
<?xml version="1.0" encoding="ISO-8859-1"?>
<MODULOS>
     <MODULO num="1">
          <COAPI>PES</COAPI>
          <DNAPI>Consultas Pesetas</DNAPI>
     </MODULO>
     <MODULO num="2">
          <COAPI>ACC</COAPI>
          <DNAPI>Control de Acceso</DNAPI>
     </MODULO>
     <MODULO num="3">
          <COAPI>ADM</COAPI>
          <DNAPI>Administración</DNAPI>
     </MODULO>
</MODULOS>
