" in the below block
1 declare
2 SBI_count pls_integer;
3 begin
4 select count(*)
5 into SBI_count
6 from xml_table,table(XMLSequence(extract(OBJECT_VALUE, '/BIF/SBI') ) );
7 dbms_output.put_line( 'SBI_count '||SBI_count );
8 for I in 1..SBI_count
9 LOOP
10 INSERT INTO Subclass_Date_Flags( Subclass_Id,
11 subclass_date_flags_8 )
12 SELECT 'SID',extractvalue(VALUE(li), '//flag')
13 FROM xml_table,table(XMLSequence(extract(OBJECT_VALUE, '/BIF/SBI[I]/SBC/flag'))) li;
14 dbms_output.put_line( 'Row '||SQL%ROWCOUNT );
15 END LOOP;
16 commit;
17* end;

Try this code, just keep a reference to your root node so you can keep appending children to it:
DECLARE
xmlDoc xmldom.DOMDocument;
xmlNode xmldom.DOMNode;
xmlNode1 xmldom.DOMNode;
xmlElem1 xmldom.DOMElement;
xmlElem2 xmldom.DOMElement;
xmlText xmldom.DOMText;
CURSOR cur_emp IS
SELECT *
FROM emp;
--WHERE empno = 7369;
row_emp emp%ROWTYPE;
BEGIN
xmlDoc := xmldom.newDOMDocument;
xmlNode := xmldom.makeNode(xmlDoc);
xmlElem1 := xmldom.createElement(xmlDoc,'root');
xmlNode := xmldom.appendChild(xmlNode,xmldom.makeNode(xmlElem1));
OPEN cur_emp;
LOOP
FETCH cur_emp INTO row_emp;
EXIT WHEN cur_emp%NOTFOUND;
xmlElem2 := xmldom.createElement(xmlDoc,'name');
xmldom.setAttribute(xmlElem2, 'empno',TO_CHAR(row_emp.empno));
xmlNode1 := xmldom.appendChild(xmlNode,xmldom.makeNode(xmlElem2));
xmlText := xmldom.createTextNode(xmlDoc,row_emp.ename);
xmlNode1 := xmldom.appendChild(xmlNode1,xmldom.makeNode(xmlText));
END LOOP;
CLOSE cur_emp;
xmldom.writeToFile(xmlDoc,'c:\xmltest1.txt');
END;
null
