XML file import to SQL database with multiple children

Question

I'm trying to import an XML file into a SQL Server database. Please have a look on the code and on the xml file. Thanks in advance.

I tried to google lot of pages but all of them deal with only one child (or how to call it).

But In my real xml the structure is like

:1x supplier --> multiple orders --> multiple customers --> multiple products. 

We need to create a stored procedure which will be called when we get the XML file.

Thanks again Petr

SQL code:

DROP TABLE #TEST

CREATE TABLE #TEST
(CUSTID VARCHAR(10),CUSTNAME VARCHAR(50),PRODUCT VARCHAR(500))

INSERT INTO #TEST(CUSTID,CUSTNAME,PRODUCT)
SELECT
    x.orders.query('order/customer/cust_id').value('.', 'VARCHAR(10)'),
    x.orders.query('order/customer/name').value('.', 'VARCHAR(50)'),
    x.orders.query('order/product_lines/product/supplier_prod_num').
   value('.','VARCHAR(500)') 
FROM
   (SELECT CAST(x AS XML)
    FROM OPENROWSET(
          BULK '\\test\Test.xml',
          SINGLE_BLOB) AS T(x)) AS T(x) 
    CROSS APPLY
        x.nodes('order_batch/orders/order/product_lines/product') AS x(orders)

select * from #test

XML file to test:

How about this:

CREATE TABLE #TEST (CUSTID VARCHAR(50), CUSTNAME VARCHAR(50), PRODUCT VARCHAR(500))

DECLARE @input XML 

SELECT @input = CAST(x AS XML)
FROM OPENROWSET
     (BULK '\\test\Test.xml',
      SINGLE_BLOB) AS T(X)

INSERT INTO #TEST(CUSTID, CUSTNAME, PRODUCT)
    SELECT
        Customers.value('(cust_id)[1]', 'VARCHAR(50)'),
        Customers.value('(name)[1]', 'VARCHAR(50)'),
        Products.value('(supplier_prod_num)[1]', 'VARCHAR(500)')
    FROM
        @input.nodes('/order_batch/orders/order') AS Tbl(Orders)
    CROSS APPLY
        Orders.nodes('customer') AS TblC(Customers)
    CROSS APPLY
        Orders.nodes('product_lines/product') AS TblP(Products)

This "shreds" the XML and uses nested CROSS APPLY .nodes() methods to extract any number of customers from the order node, and any number of products, too.
