Reading multiple child nodes in XML using openxml (SQL Server 2005) - openxml

Question

XML Tree is -
<OrderLine>
<Item>ABC</Item>
<Lot>
<Serial>SR1</Serial>
<Quantity>1</Quantity>
</Lot>
<Lot>
<Serial>SR1</Serial>
<Quantity>1</Quantity>
</Lot>
</OrderLine>
While trying to parse this tree for element values using openxml in SQL Server 2005 (stored procedure) only one is read.
Here's the code -
select item, lots
from openxml(#intDataAreaRoot, 'OrderLine', 2)
with ( item nvarchar(31) 'Item',
lots xml 'Lot'
)
I use this to declare a cursor and then parse & process as many lines as there may be in the tree. But each "fetch" brings only one "Lot" node. I need to process all "Lot" nodes under the "OrderLine" node.
Appreciate any help.

Try something like this, using the native XQuery support in SQL Server 2005:
DECLARE #intDataAreaRoot XML = '<OrderLine>
<Item>ABC</Item>
<Lot>
<Serial>SR1</Serial>
<Quantity>1</Quantity>
</Lot>
<Lot>
<Serial>SR2</Serial>
<Quantity>21</Quantity>
</Lot>
</OrderLine>'
SELECT
Item = #intDataAreaRoot.value('(/OrderLine/Item)[1]', 'varchar(25)'),
xc.value('(Serial)[1]', 'varchar(20)'),
xc.value('(Quantity)[1]', 'int')
FROM
#intDataAreaRoot.nodes('/OrderLine/Lot') AS XT(XC)
This gives me an output of :
Item (No column name) (No column name)
---------------------------------------------
ABC SR1 1
ABC SR2 21
