How to insert rows from an xml file to a table

Question

im Using Oracle 11g It is showing below error when i execute..
declare
charString varchar2(80);
finalStr varchar2(400) := null;
rowsp integer;
v_FileHandle UTL_FILE.FILE_TYPE;
begin
-- the name of the table as specified in our DTD
xmlgen.setRowsetTag('Zipcodes');
-- the name of the data set as specified in our DTD
xmlgen.setRowTag('mappings');
-- for getting the output on the screen
dbms_output.enable(100000);
-- open the XML document in read only mode
v_FileHandle := utl_file.fopen(TMP_DIR1,'XML_NEW_CITIES.XML', 'r');
loop
BEGIN
utl_file.get_line(v_FileHandle, charString);
exception
when no_data_found then
utl_file.fclose(v_FileHandle);
exit;
END;
dbms_output.put_line(charString);
if finalStr is not null then
finalStr := finalStr || charString;
else
finalStr := charString;
end if;
end loop;
-- for inserting the XML data into the table
rowsp := xmlgen.insertXML('SYS.ZIPCODES',finalStr);
dbms_output.put_line('INSERT DONE '||TO_CHAR(rowsp));
xmlgen.resetOptions;
end;
XML_NEW_CITIES.XML is
<?xml version = '1.0'?>
<Zipcodes>
<mappings Record="4">
<STATE_ABBREVIATION>CA</STATE_ABBREVIATION>
<ZIPCODE>94301</ZIPCODE>
<CITY>Palo Alto</CITY>
</mappings>
<mappings Record="5">
<STATE_ABBREVIATION>CO</STATE_ABBREVIATION>
<ZIPCODE>80323</ZIPCODE>
<ZIP_CODE_EXTN>9277</ZIP_CODE_EXTN>
<CITY>Boulder</CITY>
</mappings>
</Zipcodes>

OK, then did you try the XMLTable example, or are you waiting for someone to write it all down for you? :)
You first have to create an Oracle directory object pointing to the physical location of your file (must be somewhere on the db server or at least a location the db server can access on the network).
Then create the procedure, in this case a simple INSERT SELECT :
SQL> create directory tmp_dir as 'c:\temp';
Directory created
SQL> create table zipcodes (
  2   state_abbreviation  varchar2(2),
  3   zipcode             varchar2(5),
  4   zip_code_extn       varchar2(10),
  5   city                varchar2(80)
  6  );
Table created
SQL> CREATE OR REPLACE PROCEDURE insertZipcodes (
  2    p_directory IN VARCHAR2
  3  , p_filename  IN VARCHAR2
  4  )
  5  IS
  6  BEGIN
  7 
  8    INSERT INTO zipcodes (state_abbreviation, zipcode, zip_code_extn, city)
  9    SELECT state_abbreviation
10         , zipcode
11         , zip_code_extn
12         , city
13    FROM XMLTable('/Zipcodes/mappings'
14           passing xmltype(bfilename(p_directory, p_filename), nls_charset_id('AL32UTF8'))
15           columns state_abbreviation varchar2(2)  path 'STATE_ABBREVIATION'
16                 , zipcode            varchar2(5)  path 'ZIPCODE'
17                 , zip_code_extn      varchar2(10) path 'ZIP_CODE_EXTN'
18                 , city               varchar2(80) path 'CITY'
19         )
20    ;
21 
22  END;
23  /
Procedure created
SQL> exec insertZipcodes('TMP_DIR', 'xml_new_cities.xml');
PL/SQL procedure successfully completed
SQL> commit;
Commit complete
SQL> select * from zipcodes;
STATE_ABBREVIATION ZIPCODE ZIP_CODE_EXTN CITY
CA                 94301                 Palo Alto
CO                 80323   9277          Boulder
