Hi all,
I am getting a problem here after loading a xml into the database. Checking some messages previously in this forum helped me a lot.

the sequence is like this:

Table

SQL> desc tbl_xml
Nome Nulo? Tipo
----------------------------------------- -------- --------
XML XMLTYPE

Procedure to import, from a file, the xml to a table

create or replace PROCEDURE p_load_xml_rafa (p_dir IN VARCHAR2,
p_filename IN VARCHAR2)
IS
l_bfile BFILE := BFILENAME(p_dir, p_filename);
l_clob CLOB;
BEGIN
DBMS_LOB.createtemporary (l_clob, TRUE);

DBMS_LOB.fileopen(l_bfile, DBMS_LOB.file_readonly);
DBMS_LOB.loadfromfile(l_clob, l_bfile, DBMS_LOB.getlength(l_bfile));
DBMS_LOB.fileclose(l_bfile);

INSERT INTO tbl_xml (xml) VALUES (XMLTYPE.createXML(l_clob));
COMMIT;

DBMS_LOB.freetemporary (l_clob);
END;
/

The procedure above runs ok.

Procedure that get the xml and get the values of eache node. I put just one part of the source code.

create or replace
procedure p_carrega_xml_arq_tabela
is
l_bfile BFILE;
l_clob CLOB;
l_parser dbms_xmlparser.Parser;
l_doc dbms_xmldom.DOMDocument;
l_doc_ender_emit dbms_xmldom.DOMDocument;
l_nl dbms_xmldom.DOMNodeList;
l_nl_ender_emit dbms_xmldom.DOMNodeList;
l_n dbms_xmldom.DOMNode;
l_temp VARCHAR2(4000);

v_caminho_emit varchar2(20);
v_caminho_dest varchar2(20);
v_caminho_ender_emit varchar2(40);
v_caminho_nfe varchar2(40);
v_caminho_ender_dest varchar2(40);
TYPE tab_type IS TABLE OF tab_ide%ROWTYPE;
t_tab tab_type := tab_type();

V_DOM XMLDOM.DOMDOCUMENT;
L_NORAIZ XMLDOM.DOMNODE;
L_ITEM XMLDOM.DOMNODELIST;

v_xml xmltype;

FUNCTION f_obtem_doc_dom
RETURN XMLDOM.DOMDOCUMENT IS
v_xml XMLTYPE;
v_parser DBMS_XMLPARSER.PARSER;
v_xmldoc XMLDOM.DOMDOCUMENT;
BEGIN
select xml into v_xml from tbl_xml;

v_parser := DBMS_XMLPARSER.NEWPARSER;
DBMS_XMLPARSER.SETVALIDATIONMODE(v_parser, FALSE);
DBMS_XMLPARSER.PARSECLOB(v_parser, v_xml.GETCLOBVAL());
V_XMLDOC := DBMS_XMLPARSER.GETDOCUMENT(v_parser);
DBMS_XMLPARSER.FREEPARSER(v_parser);
RETURN v_xmldoc;

EXCEPTION
WHEN OTHERS THEN
NULL ;
RAISE;
END f_obtem_doc_dom;

BEGIN

V_DOM := f_obtem_doc_dom;
l_noraiz := XMLDOM.MAKENODE(v_dom);
l_item := dbms_xslprocessor.selectNodes(l_noraiz,'/NFe/infNFe/ide');

dbms_output.put_line(' DBMS_XMLDOM.GETLENGTH(L_NL) -1) = '|| DBMS_XMLDOM.GETLENGTH(L_item));

FOR cur_emp IN 0 .. dbms_xmldom.getLength(l_item) - 1 LOOP
l_n := dbms_xmldom.item(l_item, cur_emp);
.
.
.
.

the error happens in the red line above.

When I use this XML
<?xml version="1.0" encoding="UTF-8" ?><NFe><infNFe versao="1.10"><ide><cUF>32</cUF><cNF>044956616</cNF> .....

it runs ok.. no errors

but this one I receive an error message

<NFe xmlns="here there is a http address"><infNFe Id="NFe32091031757503000130550000000053690449566168" versao="1.10"><ide><cUF>32</cUF> ....

the error message is:
ORA-06502: PL/SQL: erro: invalid LOB locator specified: ORA-22275 number or value error
ORA-06512: em "SYS.DBMS_LOB", line 533
ORA-06512: em "SYSNFE.P_CARREGA_XML_ARQ_TABELA", line 147
ORA-06502: PL/SQL: erro numérico ou de valor
ORA-06512: em line 1

Does anyone have any idea?

Thanks in advance
Rafael

You need to help us by following the Posting Guidelines as stated below.
http://www.orafaq.com/forum/t/88153/0/
Go to the URL above click the link "Posting Guidelines"
Go to the section labeled "Practice" & do as directed.

// *Cause:  There are several causes:  (1) the LOB locator was never
//          initialized; (2) the locator is for a BFILE and the routine
//          expects a BLOB/CLOB/NCLOB locator; (3) the locator is for a
//          BLOB/CLOB/NCLOB and the routine expects a BFILE locator;
//          (4) trying to update the LOB in a trigger body -- LOBs in
//          trigger bodies are read only; (5) the locator is for a 
//          BFILE/BLOB and the routine expects a CLOB/NCLOB locator;
//          (6) the locator is for a CLOB/NCLOB and the routine expects 
//          a BFILE/BLOB locator;
// *Action: For (1), initialize the LOB locator by selecting into the locator
//          variable or by setting the LOB locator to empty.  For (2),(3),
//          (5) and (6)pass the correct type of locator into the routine.  
//          For (4), remove the trigger body code that updates the LOB value.

We can not reproduce problem without the whole & functioning procedure.

....
is inadequate

Get rid off all the stupid "when other" exception handlers first, which do nothing but mask the real errors.
