sql解析xml，學習重點建議先 對xml結構的了解，和對xpath路徑的熟悉，等等，xpath據說是w3c標准的，有興趣可以重點了解下
除了下面的（１）
另附，（２）sqlXML操作，http://www.cnblogs.com/l1pe1/archive/2010/07/28/1787254.html

示例1：從XML中解析數據到表變量
DECLARE @ItemMessage XML
DECLARE @ItemTable TABLE(ItemNumber INT PRIMARY KEY,ItemDescription NVARCHAR(300))
SET @ItemMessage=N'<ItemList>
<Item>
<ItemNumber>1</ItemNumber>
<ItemDescription>XBox 360,超值</ItemDescription>
</Item>
<Item>
<ItemNumber>2</ItemNumber>
<ItemDescription>Windows Phone7,快來嘗鮮吧</ItemDescription>
</Item>
</ItemList>'
INSERT INTO @ItemTable
(
ItemNumber,
ItemDescription
)
SELECT T.c.value('(ItemNumber/text())[1]','INT'),
T.c.value('(ItemDescription/text())[1]','NVARCHAR(300)')
FROM @ItemMessage.nodes('/ItemList/Item') AS T(c)
SELECT ItemNumber,
ItemDescription
FROM @ItemTable
運行結果：
ItemNumber ItemDescription
1 XBos 360超值
2 Windows Phone7 快來嘗鮮吧
示例二： 解析帶命名空間的XML數據
DECLARE @ItemMessage XML
DECLARE @ItemTable TABLE(ItemNumber INT PRIMARY KEY,ItemDescription NVARCHAR(300))
SET @ItemMessage=N'<ItemList xmlns="http://cd.love.com/SOA">
<Item>
<ItemNumber>1</ItemNumber>
<ItemDescription>XBox 360,超值</ItemDescription>
</Item>
<Item>
<ItemNumber>2</ItemNumber>
<ItemDescription>Windows Phone7,快來嘗鮮吧</ItemDescription>
</Item>
</ItemList>'
;WITH XMLNAMESPACES(DEFAULT 'http://cd.love.com/SOA')
INSERT INTO @ItemTable
(
ItemNumber,
ItemDescription
)
SELECT T.c.value('(ItemNumber/text())[1]','INT'),
T.c.value('(ItemDescription/text())[1]','NVARCHAR(300)')
FROM @ItemMessage.nodes('/ItemList/Item') AS T(c)
SELECT ItemNumber,
ItemDescription
FROM @ItemTable
運行結果：(同示例一)
