Select XML into a XML variable in SQL Server ignoring namespaces - sql-server

Question

I have an XML file which looks something like this
<?xml version="1.0" encoding="utf-8"?>
<Model format="1" heartbeat="PT2S">
lots of other nodes.
</Model>
I am doing the following before trying to shred the xml. However, I only want the Model node and its Childrens etc.
Declare #xml XML
set #xml = '<?xml version="1.0" encoding="utf-8"?>
<Model format="1" heartbeat="PT2S">
lots of other nodes.
</Model>'
How do i only get the Model Section ignoring the namespace/directive. Directive in this instance of XML.
e.g. Select #xml (after removing the namespace/directive will give me the following)
<Model format="1" heartbeat="PT2S">
lots of other nodes.
</Model>
I am using SQL Server 2014. Thanks in advance.

Answer 1

If I understand you correctly, you need:
Declare #xml XML
set #xml = '<?xml version="1.0" encoding="utf-8"?>
<Model format="1" heartbeat="PT2S">
lots of other nodes.
</Model>'
SELECT #xml.query('Model')

Answer 2

I do not quite understand what you mean:
DECLARE #xml XML=
'<?xml version="1.0" encoding="utf-8"?>
<Model format="1" heartbeat="PT2S">
<test>lots of other nodes.</test>
</Model>';
SELECT #xml;
returns
<Model format="1" heartbeat="PT2S">
<test>lots of other nodes.</test>
</Model>
You speak about namespace and directive. This you should know:
Namespace
If your XML has got a namespace, you did not show this to us.
A namespace must either
be specified (at least the default namespace xmlsn)
or you must use a wildcard *:
Directive
Your <?xml version="1.0" encoding="utf-8"?> will be omitted in any case. internally SQL Server stores XML as unicode (which was UTF-16) and you are not allowed to set your own directive to an XML. That's why the simple SELECT #xml returns without the directive.
Sometimes people have troubles with special characters, which need a N before the literal, because in this case the engine complains due to the UTF-8:
DECLARE #xml XML=
N'<?xml version="1.0" encoding="utf-8"?>
<Model>
Test
</Model>';
This just as a side note...
Read your XML
To get a result in any case you might try this:
Assuming an existing default namespace
DECLARE #xml XML=
'<?xml version="1.0" encoding="utf-8"?>
<Model xmlns="tempTest" format="1" heartbeat="PT2S">
<test>lots of other nodes.</test>
</Model>';
SELECT #xml.query('/*:Model/*');

Answer 3

You can use the value function. This gets the contents of the model node as nvarchar(max):
select #xml.value('/Model[1]', 'nvarchar(max)')

Answer 4

All nodes of Model as separate rows
Declare #xml XML;
set #xml = '<?xml version="1.0" encoding="utf-8"?>
<Model format="1" heartbeat="PT2S">
<lots/> <of/> <other/> <nodes./>
</Model>';
select t.n.query('.')
from
#xml.nodes('Model/*') t(n);
