Print XML attribute in SQL Server - sql-server-2008

Question

I am trying to get value of an attribute from XML in SQL table
<?xml version="1.0" encoding="utf-8"?>
<container>
<Property Name="paramA" Vocabulary="someVocu">
<Property Name="paramB" Value="valueA" />
<Property Name="paramC" Value="valueB" />
</Property>
<Property Name="paramA" Vocabulary="anotherVocu">
<Property Name="paramB" Value="valueY" />
<Property Name="paramC" Value="valueZ" />
</Property>
</container>
select x.XmlCol.value('(Property[#Name="paramB"]/#Value)[1]', 'varchar(50)') from tempTbl CROSS APPLY rawxml.nodes('/container') AS x(XmlCol)
I am trying to print "valueA" and "valueY" I am getting a NULL.
How can I do this?
Thanks

I cannot tell you what in particular is wrong with your statement since I am still learning how to query XML too. I was able to come up with some SQL which I think should work for by referencing this question...
How to query for Xml values and attributes from table in SQL Server?
Here it is.
CREATE TABLE tempTbl
(
id INT,
data XML
)
INSERT INTO dbo.tempTbl
(id, data)
SELECT 1, '<?xml version="1.0" encoding="utf-8"?>
<container>
<Property Name="paramA" Vocabulary="someVocu">
<Property Name="paramB" Value="valueA" />
<Property Name="paramC" Value="valueB" />
</Property>
<Property Name="paramA" Vocabulary="anotherVocu">
<Property Name="paramB" Value="valueY" />
<Property Name="paramC" Value="valueZ" />
</Property>
</container>'
SELECT
x.XmlCol.value('#Value', 'varchar(25)') AS Value
FROM tempTbl AS t
CROSS APPLY t.data.nodes('/container/Property/Property') AS x(XmlCol)
WHERE x.XmlCol.value('#Name', 'varchar(25)') = 'paramB'
To learn more about querying XML I am working through Stairway to XML.
