How to insert XML to SQL - sql

Question

I try to add a XML file to SQL 2008.
My XML:
<ItemList>
<Section Index="0" Name="cat0">
<Item Index="0" Slot="0" />
<Item Index="1" Slot="0" />
</Section>
<Section Index="1" Name="cat1">
<Item Index="33" Slot="0" />
<Item Index="54" Slot="0" />
</Section>
<Section Index="2" Name="cat2">
<Item Index="55" Slot="0" />
<Item Index="78" Slot="0" />
</Section>
</ItemList>
SQL Column :
Name = Section Name,
Cat = Section Index,
Index = Item Index,
Slot = Item Slot.
My Example :
DECLARE #input XML = 'MY XML file'
SELECT
Name = XCol.value('#Index','varchar(25)'),
Cat = XCol.value('#Name','varchar(25)'),
[Index] = 'Unknown', /* Index from <Item>*/
Slot = 'Unknown' /* Slot from <Item> */
FROM #input.nodes('/ItemList/Section') AS test(XCol)
I don't know how to add values from "Item".
Thank you very much!

Answer 1

You can do it like this:
select
Name = XCol.value('../#Index','varchar(25)'),
Cat = XCol.value('../#Name','varchar(25)'),
[Index] = XCol.value('#Index','varchar(25)'),
Slot = XCol.value('#Slot','varchar(25)')
from
#input.nodes('/ItemList/Section/Item') AS test(XCol)
Key idea: take data one level deeper, not /ItemList/Section, but /ItemList/Section/Item. So in this case you are able to access attributes of Item and also you can access attributes of parent element (Section in your case) by specifying ../#Attribute_Name

Answer 2

Different than the previous answer - CROSS APPLY with the children Item nodes:
SELECT
Name = XCol.value('#Index','varchar(25)'),
Cat = XCol.value('#Name','varchar(25)'),
[Index] = XCol2.value('#Index','varchar(25)'),
Slot = XCol2.value('#Slot','varchar(25)')
FROM #input.nodes('/ItemList/Section') AS test(XCol)
CROSS APPLY XCol.nodes('Item') AS test2(XCol2)
