XML conversion issues

Question

Dear all,
I am using oracle8i. I would be pleased, if you could answer for this questions.
create table dept(deptno number,
dname varchar2(20),
loc varchar2(20));
alter table dept add primary key(deptno);
create table emp(empno number,
ename varchar2(20),
deptno number);
alter table emp add primary key(empno);
alter table emp add constraint fk_dept foreign key(deptno) references dept;
insert into dept values(10,'Account','Houston');
insert into dept values(20,'Finance','Austin');
insert into dept values(30,'Finance',NULL);
insert into emp values(101,'Krish',10);
insert into emp values(102,'Sam', 10);
insert into emp values(103,'Scott',20);
insert into emp values(104,'Brent',20);
I have a procedure to covert the data into XML.
CREATE OR REPLACE PROCEDURE STP_SAMPLE_XML AS
v_context DBMS_XMLQUERY.CTXTYPE;
v_document CLOB;
v_offset NUMBER := 1;
v_chunk VARCHAR2(4000);
v_chunk_size NUMBER := 4000;
l_file UTL_FILE.FILE_TYPE;
BEGIN
l_file := UTL_FILE.FOPEN('D:\Data\XMLFILES', 'sample.XML', 'w');
v_context:= DBMS_XMLQUERY.NEWCONTEXT('SELECT DEPTNO,DNAME,LOC,
CURSOR(SELECT EMPNO,ENAME,DEPTNO
FROM EMP EMP_DETAILS
WHERE EMP_DETAILS.DEPTNO = DEPT.DEPTNO) EMP_PAYEE
FROM DEPT');
DBMS_XMLQUERY.USENULLATTRIBUTEINDICATOR(v_context,TRUE);
DBMS_XMLQUERY.SETROWSETTAG(v_context,'EMP');
DBMS_XMLQUERY.SETROWTAG(v_context,'EMP');
v_document := DBMS_XMLQUERY.GETXML(v_context);
WHILE( v_offset < DBMS_LOB.GETLENGTH( v_document))
LOOP
v_chunk := DBMS_LOB.SUBSTR(v_document,v_chunk_size,v_offset );
UTL_FILE.PUT(l_file, v_chunk );
v_offset := v_offset + v_chunk_size;
END LOOP;
UTL_FILE.FCLOSE(l_file);
DBMS_XMLQUERY.CLOSECONTEXT(V_context);
END;
This procedure gives the below output.
<?xml version="1.0" ?>
- <EMP>
- <EMP num="1">
<DEPTNO>10</DEPTNO>
<DNAME>Account</DNAME>
<LOC>Houston</LOC>
- <EMP_PAYEE>
- <EMP_PAYEE_ROW num="1">
<EMPNO>101</EMPNO>
<ENAME>Krish</ENAME>
<DEPTNO>10</DEPTNO>
</EMP_PAYEE_ROW>
- <EMP_PAYEE_ROW num="2">
<EMPNO>102</EMPNO>
<ENAME>Sam</ENAME>
<DEPTNO>10</DEPTNO>
</EMP_PAYEE_ROW>
</EMP_PAYEE>
</EMP>
- <EMP num="2">
<DEPTNO>20</DEPTNO>
<DNAME>Finance</DNAME>
<LOC>Austin</LOC>
- <EMP_PAYEE>
- <EMP_PAYEE_ROW num="1">
<EMPNO>103</EMPNO>
<ENAME>Scott</ENAME>
<DEPTNO>20</DEPTNO>
</EMP_PAYEE_ROW>
- <EMP_PAYEE_ROW num="2">
<EMPNO>104</EMPNO>
<ENAME>Brent</ENAME>
<DEPTNO>20</DEPTNO>
</EMP_PAYEE_ROW>
</EMP_PAYEE>
</EMP>
</EMP>
But i want to achive the output as below. How can i do this ?.
I want to remove - <EMP_PAYEE_ROW num="1"> tags, and
i want to change the tag <EMP_PAYEE> to <EMP-PAYEE> tag,
<?xml version="1.0" ?>
- <EMPIMPORT>
- <EMP>
<DEPTNO>10</DEPTNO>
<DNAME>Account</DNAME>
<LOC>Houston</LOC>
- <EMP-PAYEE>
<EMPNO>101</EMPNO>
<ENAME>Krish</ENAME>
<DEPTNO>10</DEPTNO>
</EMP-PAYEE/>
- <EMP-PAYEE>
<EMPNO>102</EMPNO>
<ENAME>Sam</ENAME>
<DEPTNO>10</DEPTNO>
</EMP-PAYEE/>
</EMP>
- <EMP>
<DEPTNO>20</DEPTNO>
<DNAME>Finance</DNAME>
<LOC>Austin</LOC>
- <EMP-PAYEE>
<EMPNO>103</EMPNO>
<ENAME>Scott</ENAME>
<DEPTNO>20</DEPTNO>
</EMP-PAYEE/>
- <EMP-PAYEE>
<EMPNO>104</EMPNO>
<ENAME>Brent</ENAME>
<DEPTNO>20</DEPTNO>
</EMP-PAYEE/>
</EMP>
</EMPIMPORT>

Govind,
Create a view of the data the way you want it displayed with the column names to match. Then produce the XML from the view.
