Hoping someone can help -
The XML format was put together with a very simple syntax, but for some reason I'm struggling to parse it using a standard 'value' type query. I'm experienced with SQL, but only have limited experience in XML, and after 2 hours of frustration and much Googling, I thought I'd ask for my own sanity!
The data is stored as a text string, so converting it to XML before parsing:
<!-- Data config file -->
<Config>
<!-- keys-->
<foo value="bar"/>
<foo1 value="bar1"/>
<big_foo value="bar/bar.com"/>
<other value="f00"/>
The query I'm using is:
SELECT
col.value('foo1[0]', 'nvarchar(max)') as VALUE
from
(
select
CAST((SELECT TOP 1 xml_text FROM dbo.xml_lookup)AS XML)
as Col)x
but this returns NULL rather than the expected "bar1".
Any idea where I'm going wrong?
