SQLXml 处理带namespace的xml

查阅了MSDN,其实很简单

sp_xml_preparedocument
hdoc 
OUTPUT
[ , xmltext ]
[ , xpath_namespaces ] 

You can specify ns using the third parameter.

declare @MailContent as nvarchar(max)
select @MailContent=MessageBody from MailStorer where ID=2

--print @MailContent

DECLARE @XmlHandler int
--Create an internal representation of the XML document.
EXEC sp_xml_preparedocument @XmlHandler OUTPUT, @MailContent,'<ns0:RN_4C1_OUT xmlns:ns0="http://_4C1_InventoryHold_Intel.MailMessage"/>'

SELECT  '4C1 Inventory Hold On/Off' as Header,*
FROM       OPENXML (@XmlHandler, '/ns0:RN_4C1_OUT/InventoryLine',1)
with
(
    Status nvarchar(50) 'Status',
    Date nvarchar(50) 'DocDate',
    IDocNo nvarchar(50) 'IDocNo',
    SKU nvarchar(50) 'SKU',
    Quantity nvarchar(50) 'Qty',
    RequestBy nvarchar(50) 'RequestBy'
)

-- 清除xml文件句柄，释放内存
exec sp_xml_removedocument @XmlHandler
