Error while generating an XML File.

Question

Hello All,
Help me regarding My Doubt.
I have created a Procedure Which will create an XML File.
I am Using the XMLDOM Package to create the File.
I am passing the XMLFILE to a CLOB Field.
XMLDOM.writeToClob(DOC, P_XMLFILE);
But When I am Running the Procedure I am getting the List of Errors.
ORA-29280: invalid directory path
ORA-06512: at "SYS.UTL_FILE", line 33
ORA-06512: at "SYS.UTL_FILE", line 436
ORA-06512: at "XDB.DBMS_XSLPROCESSOR", line 217
ORA-29280: invalid directory path
ORA-29280: invalid directory path
ORA-06512: at "XDB.DBMS_XMLDOM", line 4416
ORA-06512: at "K5ESK_LDB2.PR_CREATE_XMLFILE", line 26
I dont know the Reason why the Errors are Comming.
Does It Require I should change the System Setting to Make sure that XMLDOM will work Properly

Dear Member,
The Below is the Code I am using.
CREATE OR REPLACE PROCEDURE pr_create_xmlfile(P_XMLFILE IN OUT CLOB)
doc xmldom.DOMDocument;
main_node xmldom.DOMNode;
root_node xmldom.DOMNode;
user_node xmldom.domnode;
item_node xmldom.domnode;
root_elmt xmldom.DOMElement;
item_elmt xmldom.DOMElement;
item_text xmldom.domtext;
CURSOR get_data(p_deptno IN NUMBER)
IS
SELECT EMPNO,
ENAME,
DEPTNO,
ROWNUM Rec_Num
FROM emp WHERE deptno = p_deptno;
BEGIN
doc := xmldom.newdomdocument;
-- Create the Main Node
main_node := xmldom.makenode(doc);
-- Create the Root Element.
root_elmt := xmldom.createelement(doc,'EMPSET');
-- Attach this Root Element to the Main Node.
root_node := xmldom.appendchild(main_node,xmldom.makenode(root_elmt));
xmldom.writetofile(doc,'c:\temp\test.xml');
xmldom.freedocument(doc);
FOR rec_data IN get_data(10) LOOP
<EMP num="1">
<EMP_NO>7782</EMP_NO>
<NAME>CLARK</NAME>
<DEPT_NO>10</DEPT_NO>
</EMP>
-- Create a Main Element
item_elmt := xmldom.createelement(doc,'EMP');
-- Creating an Attribute to the Emp Element
xmldom.setattribute(item_elmt,'Num',rec_data.rec_num);
-- Attaching this EMP Element as Child Record to the Root Node.
user_node := xmldom.appendchild(root_node,xmldom.makenode(item_elmt));
-- Creating another EMP_NO Element
item_elmt := xmldom.createelement(doc,'EMP_NO');
-- Attaching the EMP_NO Element to the EMP Element as Child Element
item_node := xmldom.appendchild(user_node,xmldom.makenode(item_elmt));
-- Creating a Text Node with the Empno data
item_text := xmldom.createtextnode(doc,rec_data.empno);
-- Attaching this Text Node as Child to the EMP_NO Element.
item_node := xmldom.appendchild(item_node,xmldom.makenode(item_text));
END LOOP;
XMLDOM.writeToClob(DOC, P_XMLFILE);
XMLDOM.FREEDOCUMENT(DOC);
Errors
