SQL Server: SELECT XML with Namespaces gives NULL Result - sql

Question

I want to load a XML File into SQL Server 2012 as a variable, one of the columns should contain the XML itself and the other columns should contain values from the XML elements.
My Issue is that I don't get an ERROR but also no record in my table, it just returned blank result
USE [testjrazt]
GO
DECLARE #doc XML
SELECT #doc = '<?xml version="1.0"?>

Here is how to do it. Your XML has a default namespace. It should be taken into account via WITH XMLNAMESPACES clause.
-- DDL and sample data population, start
DECLARE #doc XML =
N'<SyncSalesOrder xmlns="http://schema.infor.com/InforOAGIS/2"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://schema.infor.com/InforOAGIS/2 http://schema.infor.com/2.12.x/InforOAGIS/BODs/SyncSalesOrder.xsd"
