将TSQL XML字段转换为多列

我有以下数据集：

Index      | xml
A          | <book><name>A book 1</name><book>
B          | <book><name>B book 1</name><book><book><name>B book 2</name><book>

我最后需要的是这张表： 索引|书名

A         | A Book 1 
B         | B Book 1 
B         | B Book 2

我似乎从这个查询中得到的是：

A         | A Book 1 
B         | B Book 1 B Book 2

我哪里做错了？如何区分字段？

这是如何工作的，我不知道。我对XML很在行。我只是看了一些例子，然后把它们放在一起。希望这有帮助

DECLARE @BookCache TABLE ([Index] CHAR,[xml] XML);
INSERT INTO @BookCache
VALUES  ('A','<book><name>A book 1</name></book>'),
        ('B','<book><name>B book 1</name></book><book><name>B book 2</name></book>');

SELECT  [Index],
        BookNameNode.value('(text())[1]','VARCHAR(25)') AS Name
FROM @BookCache
CROSS APPLY [Xml].nodes('/book/name') AS [test](BookNameNode)

你能提供你从哪里抓到的吗！？这正是我一直在寻找的！谷歌似乎给我带来了一堆垃圾！哈哈：）我从公认的答案中得到了一个例子：

DECLARE @BookCache TABLE ([Index] CHAR,[xml] XML);
INSERT INTO @BookCache
VALUES  ('A','<book><name>A book 1</name></book>'),
        ('B','<book><name>B book 1</name></book><book><name>B book 2</name></book>');

SELECT  [Index],
        BookNameNode.value('(text())[1]','VARCHAR(25)') AS Name
FROM @BookCache
CROSS APPLY [Xml].nodes('/book/name') AS [test](BookNameNode)

Index  Name
-----  -------
A      A book 1
B      B book 1
B      B book 2
