Logic for inserting values from Pl/sql table

Question

Hi I'm using Forms 6i and db 10.2.0.1.0
I am reading an xml file using text_io, and extracting the contents to Pl/sql table.
Suppose, the xml
<?xml version="1.0" encoding="UTF-8" ?>
  <XML>
  <File name="S2_240463.201002170044.Z">
  <BookingEnvelope>
  <SenderID>KNPROD</SenderID>
  <ReceiverID>NVOCC</ReceiverID>
  <Password>TradingPartners</Password>
  </BookingEnvelope>
</File>
</XML>From this xml, i'm extracting contents to a table of records, say bk_arr, which look like
Tag                             Val
File name                     S2_240463.201002170044.Z
SenderID                     KNPROD
ReceiverID                   NVOCC
Password                     TradingPartnersAnd now from this i've to insert into table, say bk_det .
The tag may come in different order, sometimes some additional tags may also come in between,
So i cannot access it sequentially and insert like
Insert into bk_det(file,sndr,rcvr,pswd) values(bk_arr(1).val,bk_arr(2).val....)
The tag name is constant ir for sender id, it will always be SenderID , not something like sndrid or sndid etc..
So if i've to insert to senderid column, then i've to match the tag = SenderID, and take the value at that index in the array.
How best i can do this?
Thanks

I am referring to how you are parsing the XML - as you can extract values from the XML by element name. And as the name is known, it's associated value can be inserted easily.
Basic example:
SQL> with XML_DATA as(
  2          select
  3                  xmltype(
  4  '<?xml version="1.0" encoding="UTF-8" ?>
  5  <XML>
  6          <File name="S2_240463.201002170044.Z">
  7                  <BookingEnvelope>
  8                          <SenderID>KNPROD</SenderID>
  9                          <ReceiverID>NVOCC</ReceiverID>
10                          <Password>TradingPartners</Password>
11                  </BookingEnvelope>
12          </File>
13  </XML>'         )       as XML_DOM
14          from    dual
15  )
16  select
17          extractValue( xml_dom, '/XML/File/@name' )                      as FILENAME,
18          extractValue( xml_dom, '/XML/File/BookingEnvelope/SenderID' )   as SENDER_ID,
19          extractValue( xml_dom, '/XML/File/BookingEnvelope/ReceiverID' ) as RECEIVER_ID,
20          extractValue( xml_dom, '/XML/File/BookingEnvelope/Password' )   as PASSWORD
21  from       xml_data
22  /
FILENAME                  SENDER_ID  RECEIVER_I PASSWORD
S2_240463.201002170044.Z  KNPROD     NVOCC      TradingPartners
SQL> Now this approach can be used as follows:
  create or replace procedure AddFile( xml varchar2 ) is
begin
        insert into foo_files(
                filename,
                sender_id,
                receiver_id,
                password
        with XML_DATA as(
                select
                        xmltype( xml ) as XML_DOM
                from    dual
        select
                extractValue( xml_dom, '/XML/File/@name' ),
                extractValue( xml_dom, '/XML/File/BookingEnvelope/SenderID' ),
                extractValue( xml_dom, '/XML/File/BookingEnvelope/ReceiverID' ),
                extractValue( xml_dom, '/XML/File/BookingEnvelope/Password' )
        from    xml_data;
end;
