XML to CLOB conversion

Question

Hello
I have a XMLTYPE field.
And I need to remove all the XML Tags and save it as CLOB.
I tried using Regexp_replace or replace but it throws
ORA-19011: Character string buffer too small error?
Any other techniques?

Hi,
You can use getCLOBval() for conversion.
CREATE TABLE EMP2 (EMPCODE NUMBER(8),EMPNAME VARCHAR2(100),EMPDEPTNO NUMBER(8),EMPSAL NUMBER(34,2));
create table EMPXML(XMLCLOB XMLTYPE);
BEGIN
FOR X IN (SELECT * FROM USER_OBJECTS S WHERE ROWNUM<=50)
LOOP
INSERT INTO EMP2 VALUES (X.OBJECT_ID,X.OBJECT_NAME,20,X.OBJECT_ID+10);
END LOOP;
COMMIT;
END;
DECLARE
v_xmldata CLOB;
BEGIN
SELECT Xmlelement("Employee",
Xmlagg(Xmlforest(e.Empcode AS "EmpId",
e.Empname AS "EmpName",
e.Empsal AS "EmpSal"))).getclobval() INTO v_xmldata
FROM Emp2 e;
INSERT INTO empxml VALUES (xmltype(v_xmldata));
END;
SELECT * FROM empxml;
DROP TABLE emp2 PURGE;
DROP TABLE empxml PURGE;
