XML解析:第1行，字符23，非法名称字符

Question

有人知道为什么这个XML文本在SQL Server 2008中抛出非法名称字符错误吗？

'<cs><c a="2" b="CITY & STATE TX" c="CITY & STATE TX"/></cs>'

异常消息为

Msg 9421, Level 16, State 1, Line 2
XML parsing: line 1, character 23, illegal name character

以下是用于解析此xml 的查询

DECLARE @CaptionsDescriptions XML = '<cs><c a="2" b="CITY & STATE TX" c="CITY & STATE TX"/></cs>'
DECLARE @DocHandle int  
DECLARE @CaptionsDescriptionsTable TABLE  
(  
 ID INT IDENTITY(1,1),  
 languageID INT,  
 Caption  VARCHAR(50),  
 Description VARCHAR(2000)  
)  
EXEC sp_xml_preparedocument @DocHandle OUTPUT,@CaptionsDescriptions    
INSERT INTO @CaptionsDescriptionsTable SELECT a,b,c  
 FROM OPENXML(@DocHandle,'cs/c')   
 WITH (  
    a int, -- language id  
    b varchar(50), -- caption  
    c varchar(2000) -- description  
   )  
-- remove document handler  
EXEC sp_xml_removedocument @DocHandle  

Answer 1

&是XML中的保留/特殊字符。应该是&

我甚至要补充一点，XML parsing: line 1, character 23, illegal name character非常清楚如果您知道SQL从1开始计数：那么第23个字符就是&。

Answer 2

您需要更改&到&

像这个一样，把你的价值放在cdata的封面下

DECLARE @CaptionsDescriptions XML = '<cs><c a="2" b="<![CDATA[CITY & STATE TX]>" c="CITY & STATE TX"/></cs>'
