1/ You posted your question at 22:57 for me and I think 23:57 for Littlefoot, so be patient and try to do it in by yourself in the meantime, we are not just waiting for your question, we also have a life.

2/ What is a "segment"? As far as I know this is not a XML notion.

3/ What should be the result in your table for your XML data? Give us the mapping of each field.

4/ Why SQL*Loader is mandatory? Why not an external table?

I am totally agree with you Sir and my apologies ....

I mean "Element" not "Segment"... value between <>.
for example : <field_name>DRCRIndicator</field_name>
<todo_group_name>Daily-CFT-ASCU</todo_group_name>

3/ What should be the result in your table for your XML data? Give us the mapping of each field.

1/ What you posted is not a CSV file, I don't know what it is
2/ "Amount ==> <field_value>33333333.33</field_value>"
They are several "<field_name>Amount</field_name>" which one to take?

storing "numbers" (like ChequeSerialNumber, Amount, ItemSequenceNumber) in VARCHAR2 columns should be avoided

This file is to show you how the data looks in table, some how your not able to open it...

Quote:

I need to get <field_value> by mapping <field_name> with database table.

for Example.

In table I have "Amount" field, now need to map <field_name>Amount</field_name> and get <field_value>33333333.33</field_value> and save it into amount field in table.

Hope this will help you to undestand...

No, it does not help.
You have
Quote:
<field>
<field_name>Amount</field_name>
<field_value>33333333.33</field_value>
</field>

and
Quote:
<field_name>Amount</field_name>
<field_value>22222222.22</field_value>
</field>

So why 33333333.33 and not 22222222.22?

If we don't know which kind of file it is, it is obvious we will not test all and every possible program to open it, above all if you give us the wrong extension.

So you want several rows for the same (something I assume as we have not a clear specification):
    <customer_name>CHQ_FT_Test</customer_name>
    <todo_group_name>Daily-CFT-ASCU</todo_group_name>
    <extraction_name>CHQ-FT-Extract</extraction_name>
    <translation_name>CHQ-FT-TranslateToTiff</translation_name>
    <scheduled_date>20060602</scheduled_date>
    <extract_period_start>20060602</extract_period_start>
    <extract_period_end>20060602</extract_period_end>
    <text_encoding>ascii</text_encoding>
    <content_type>cheque</content_type>
    <checksum_field_name>Amount</checksum_field_name>
    <data_file_name> PSYM.CHCK.C9998.DATA.D070418.T135513.C0101 </data_file_name>
    <data_file_name_2>cccccccc</data_file_name_2>

Is this one row per <item>?
In this case you should have 2 tables: a parent one for the <header> information (defining the customer if I understand) and a child one for each <item> (defining a transaction, still if I understand the data).

If your data file is on your server, not your client, then you should be able to select from it directly, using bfilename. You can then use xmltable and max and decode to pivot the values. In the demonstration below, I have retrieved 3 columns from the header and 3 columns from the body. I have marked each place where you would need to add more code for each column with "-- and so on ...". You should be able to detect the pattern and complete the code.
