Export table to formatted xml

Question

I have an oracle table i have to export as formatted xml
I really want the data to look like this : (and need to get rid of the cdata)
<?xml version='1.0' ? XML_DATE = "2012-06-26 08:12:09 PM">
<APPLICATION NAME = "XMLTESTING">
     <WEBPAGE>
          <PROJECT>
<column1>ABC</column1>
<column2>DEF</column2>
<column3>GHI</column3>
<column4>JKL</column4>
<column5>MNO</column5>
</PROJECT>
<PROJECT>
<column1>ABG</column1>
<column2>DRF</column2>
<column3>GLY</column3>
<column4>JAL</column4>
<column5>MPO</column5>
</PROJECT>
<PROJECT>
<column1>BBC</column1>
<column2>GEF</column2>
<column3>LHI</column3>
<column4>JCL</column4>
<column5>MWO</column5>
</PROJECT>
</WEBPAGE>
</APPLICATION>
create table "XML_TESTING" (
"column1" varchar2(50byte),
"column2" varchar2(50byte),
"column3" varchar2(50byte),
"column4" varchar2(50byte),
"column5" varchar2(50byte)
INSERT into XML_TESTING values ('ABC','DEF','GHI','JKL','MNO');
INSERT into XML_TESTING values ('ABG','DRF','GLY','JAL','MPO');
INSERT into XML_TESTING values ('BBC','GEF','LHI','JCL','MWO');
CREATE TABLE xml_cl(result CLOB);
DECLARE
ctxqry DBMS_XMLGEN.ctxHandle;
result CLOB;
BEGIN
ctxqry := dbms_xmlgen.newContext('SELECT * FROM xml_testing');
DBMS_XMLGEN.setRowTag(ctxqry,'APPLICATIO NAME = "XML TESTING"');
--DBMS_XMLGEN.setMaxRows(ctxqry,5);
DBMS_XMLGEN.setrowsettag(ctxqry,'WEBPAGE');
LOOP
result := DBMS_XMLGEN.getXML(ctxqry);
EXIT WHEN
DBMS_XMLGEN.getNumRowsProcessed(ctxqry)=0;
INSERT INTO xml_cl VALUES(result);
END LOOP;
END;
SELECT * FROM xml_cl
THEN I EXPORT TO XML FROM HERE.
this is how xml currently looks
<?xml version='1.0' encoding='Cp1252' ?>

Use SQL/XML functions to build and serialize the document as CLOB in a single query :
SQL> SELECT XMLSerialize(document
  2           XMLElement("APPLICATION",
  3             XMLAttributes('XMLTESTING' as "NAME")
  4           , XMLElement("WEBPAGE",
  5               XMLAgg(
  6                 XMLElement("PROJECT",
  7                   XMLForest("column1", "column2", "column3", "column4", "column5")
  8                 )
  9               )
10             )
11           )
12           as clob
13           indent --< for formatting purpose only
14         )
15  FROM xml_testing
16  ;
XMLSERIALIZE(DOCUMENTXMLELEMEN
<APPLICATION NAME="XMLTESTING">
  <WEBPAGE>
    <PROJECT>
      <column1>ABC</column1>
      <column2>DEF</column2>
      <column3>GHI</column3>
      <column4>JKL</column4>
      <column5>MNO</column5>
    </PROJECT>
    <PROJECT>
      <column1>ABG</column1>
      <column2>DRF</column2>
      <column3>GLY</column3>
      <column4>JAL</column4>
      <column5>MPO</column5>
    </PROJECT>
    <PROJECT>
      <column1>BBC</column1>
      <column2>GEF</column2>
      <column3>LHI</column3>
      <column4>JCL</column4>
      <column5>MWO</column5>
    </PROJECT>
  </WEBPAGE>
</APPLICATION>
Then you can call DBMS_XSLPROCESSOR.CLOB2FILE to write the CLOB to a file, no need of an intermediate table.
