在 SQL 中声明 XML 变量时出现非法 XML 个字符

Question

问题

我试图在我的 SQL 查询中声明一个 XML 变量并将其设置为等于 this XML 文件，如下所示：DECLARE @x XML = 'xml content here'; . 但是，当我尝试使用当前的 XML 文件执行此操作时，我的屏幕上显示了以下错误消息：

Msg 9420, Level 16, State 1, Line 1 XML parsing: line 1132, character 265, illegal xml character

我已经尝试解决的方法

我试图通过用两个单引号替换 XML 文件中的所有单引号然后复制到查询中来转义单引号。没有运气。
我试过去掉 & 符号，但这似乎不起作用。在 SQL 检测到错误的附近，似乎没有任何特殊字符。又没运气了。

问题

在我看来，单引号不是问题所在。我无法准确找到非法字符是什么，以及如何过滤掉这些字符。也许从外部文件导入 XML 文件并将内容设置为变量而不是听到编码将解决问题。这将如何工作？我也知道单引号必须用两个单引号代替。我做到了，但我仍然有完全相同的问题。感谢任何帮助理解这个问题。

这是我正在执行的给出错误的完整代码：

DECLARE @x XML = ' copy xml file here... ';

With MyPersonCTE AS
(
    SELECT ROW_NUMBER() OVER(ORDER BY (SELECT NULL)) AS PersonID
          ,p.value('FirstName[1]','varchar(max)') AS FirstName
          ,p.value('LastName[1]','varchar(max)') AS LastName
          ,p.value('Biography[1]','varchar(max)') AS Biography
          ,p.value('Expertise[1]','varchar(max)') AS Expertise
          ,p.value('Image[1]','varchar(max)') AS Image
          ,p.value('Link[1]','varchar(max)') AS Link
          ,p.query('Books') AS BookNode
          ,p.query('Articles') AS ArticleNode
          --same for Papers, Artwork...
    FROM @x.nodes('/People/Person') AS A(p) 
)
,MyBooksCTE AS
(
    SELECT MyPersonCTE.*
          ,ROW_NUMBER() OVER(ORDER BY (SELECT NULL)) AS BookID
          ,x.value('Year[1]','int') AS BookYear
          ,x.value('Details[1]','varchar(max)') AS BookDetails
    FROM MyPersonCTE
    CROSS APPLY MyPersonCTE.BookNode.nodes('/Books/Book') A(x)  
)
,MyArticlesCTE AS
(
    SELECT MyPersonCTE.*
          ,ROW_NUMBER() OVER(ORDER BY (SELECT NULL)) AS ArticleID
          ,x.value('Year[1]','int') AS ArticleYear
          ,x.value('Details[1]','varchar(max)') AS ArticleDetails
    FROM MyPersonCTE
    CROSS APPLY MyPersonCTE.ArticleNode.nodes('/Articles/Article') A(x)  
)
--same for Papers, Artwork...
SELECT p.*
      ,b.BookID
      ,b.BookYear
      ,b.BookDetails
      ,a.ArticleID
      ,a.ArticleYear
      ,a.ArticleDetails  
INTO #tempAllData
FROM MyPersonCTE AS p
LEFT JOIN MyBooksCTE AS b ON p.PersonID=b.PersonID
LEFT JOIN MyArticlesCTE AS a ON p.PersonID=a.PersonID ;

--#tempAllData is now filled with all data, copied in all combination: much to much
--but DISTINCT is your friend
--in this case you'd use the PersonID as FK in all related tables

SELECT DISTINCT PersonID,FirstName,LastName,Biography,Expertise --other fields
FROM #tempAllData;

SELECT DISTINCT PersonID,BookID,BookYear,BookDetails
FROM #tempAllData;

SELECT DISTINCT PersonID,ArticleID,ArticleYear,ArticleDetails
FROM #tempAllData;

DROP TABLE #tempAllData;

看，这是重现错误的简化示例

SELECT @x;

现在只需更改此

'<?xml version="1.0" encoding="UTF-8"?>

到这个（不要忘记开头的"N"强制这个到Unicode）

N'<?xml version="1.0" encoding="UTF-16"?>

但试试这个：

DECLARE @yourXML AS XML=
(
SELECT CONVERT(XML, BulkColumn,2) AS BulkColumn
FROM OPENROWSET(BULK 'X:\Path2file\faculty-xml.xml', SINGLE_BLOB) AS x
);
SELECT @yourXML;

有了这个，您就不必为环境而烦恼，您只需从磁盘上的某个位置读取文件...
