How to query CLOB?

Question

One of the table column stores XML file as CLOB. Now, there is a requirement to retrieve the CLOB if one of the element matches within XML file.
Please could someone suggest what is the best way to do that.
Here is my table structure
TABLEA
COL1 COL2 COL3
String String CLOB (XML)
To get an idea, this is what i need to achieve: select * from TABLEA if COL3 contains (AccountType == "CLS").

Hello,
If entire xml loaded you can just simply do a search using like or regexp_like (depending upon how complex search string) is
Here is a simple example to load a file or number for files and search
CREATE TABLE XML_TABLE1
  XML_USER VARCHAR2(30),
  XML_TEST VARCHAR2(30),
  XML_DATA  CLOB                                    NULL
DECLARE
   clob_data   CLOB;
   clob_file   BFILE;
BEGIN
   INSERT INTO xml_table1
   VALUES (EMPTY_CLOB ())
   RETURNING xml_data INTO clob_data;
   clob_file   := BFILENAME ('XMLDIR', 'test.xml');
   DBMS_LOB.fileopen (clob_file);
   DBMS_LOB.loadfromfile (clob_data,
                          clob_file,
                          DBMS_LOB.getlength (clob_file)
   DBMS_LOB.fileclose (clob_file);
   COMMIT;
END;
select * from xml_table1
where xml_data like ('%tester1%')Regards
