DECLARE
g_xdoc XMLTYPE;
g_trans_type CHAR (20) := NULL;
BEGIN
SELECT xmltype(c) -- column is a clob column
INTO g_xdoc
FROM test_gil
WHERE a = '1';


SELECT EXTRACT(VALUE (tt), '//transactionType').getstringval()
INTO g_trans_type
FROM TABLE (XMLSEQUENCE (EXTRACT (g_xdoc, '/'))) tt;

What confuses me to this is that once I format the XML and run the same query it runs fine....

Try:
select extractvalue(value(x),'//transactionType') v
into g_trans_type
from test_gil, 
     table(xmlsequence(extract(xmltype(c),'//transactionType'))) x
WHERE a = '1';

Maybe the line is too long.

For reference:
ORA-30951: Element or attribute at Xpath %s exceeds maximum length
 *Cause:   An attempt was made to insert a node of length exceeding the
           maximum length (specified by the maxLength facet) into
           an XML document.
 *Action:  Do not attempt to add a node exceeding the maximum length
           to XML documents.

Regards
Michel

Try:
select extractvalue(value(x),
                    '//transactionType',
                    'xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"') v
into g_trans_type
from test_gil, 
     table(xmlsequence(extract(xmltype(c),
                               '//transactionType',
                               'xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"'))) x
WHERE a = '1';

But you may have reached a limit.

Michel

Sorry, I modified my post when you were testing, I missed to put the "xmlns" reference in the "table" part.
Could you retry, but I'm afraid you will have to preprocess the clob to split the XML expression.

Michel

Hi there

I still get the same error do you thing if I split the XML in the CLOB it would do a difference?
Or what is the best way to wrap the XML because when I format the XML it works fine...

Yes, this is what I meant by "split", it was "wrap", sorry for this misuse of the word.
You can add a newline between each "><" in SQL:
select extractvalue(value(x),'//transactionType') v
into g_trans_type
from test_gil, 
     table(xmlsequence(extract(
                         xmltype(replace(c, '><', '>'||chr(10)||'<')),
                         '//transactionType'))) x
WHERE a = '1';

Regards
Michel

Hi guys

As for the extract part I used a Java Stored Procedure to etract the value and its working now I am getting the same error when trying to (isSchemaValid (); and schemaValidate ();0 please check code below

set serveroutput on

DECLARE
x CLOB;
v_xdoc XMLTYPE;
g_status VARCHAR2 (50);
g_msg VARCHAR2 (2000);
v_xml_ok NUMBER;
BEGIN
SELECT c --clob column from the database
INTO x
FROM test_gil
WHERE a = '1 - insert_online_xml'
AND b = 'p_message_id :FAIL201304261415231348, UNKNOWN';
v_xdoc := xmltype (x);
-- Associate an XSD to the XML
v_xdoc := v_xdoc.createSchemaBasedXML ('NXS_CLAIM_REQ.XSD');

BEGIN
-- Validate the XML received against the XSD - 0=INVALID, 1=VALID
v_xml_ok := v_xdoc.isSchemaValid ();
EXCEPTION
WHEN OTHERS
THEN
DBMS_OUTPUT.put_line (
'XML does not correspond to schema.' || SQLERRM);
END;

-- Find out what is invalid so as to return a more meaningful message
IF v_xml_ok = 0
THEN
BEGIN
v_xdoc.schemaValidate ();
EXCEPTION
WHEN OTHERS
THEN
DBMS_OUTPUT.put_line ('XML does not conform to XSD..' || SQLERRM);
END;
END IF;

mds_web_service_pack.validate_xml (x,
'NXS_CLAIM_REQ.XSD',
v_xdoc,
g_status,
g_msg);
END;

As you didn't feedback nor thank after your previous question above, I don't see any reason I'll help you now.

Sorry Michel man..... Really sorry been a very stressful week at work...
I tried all the solutions given but to no success, until on Metalink I was advised that this was an Oracle bug(See Below)...as below this apparently is happening at RegisterSchema level hence the extract part does not work as well...

So now I am trying to write the Java Stored Procs to do the same functionality... But I am struggling on some parts I have mentioned previously...

Again Sorry Michel, I truly appreciate your help
