我正在尝试读取XML文件。

我写了这个脚本,但是我遇到了错误:

代码语言:javascript
复制
DECLARE @XML AS XML, @hDoc AS INT, @SQL NVARCHAR (MAX), @rootxmlns varchar(1000)    

SELECT @XML=CONVERT(XML, BulkColumn) 
FROM OPENROWSET(BULK 'F:\__Files\Done\Output\20201223133856\2027.txt.xmi', SINGLE_BLOB) AS x;

SET @rootxmlns = '<root xmlns:soap="http://www.omg.org/XMI"/>'
EXEC sp_xml_preparedocument @hDoc OUTPUT, @XML, @rootxmlns

SELECT *
FROM OPENXML(@hDoc, 'Matrix:Customer')

我检查了许多链接,它们都建议使用xmlns,我尝试了许多链接,但是它们都没有处理相同的错误。

XML解析错误:引用未声明的命名空间前缀:“Customer”。

这是我的XMI

我必须通过添加伪命名空间来修复输入XML。最好使用XQuery本机方法:.nodes().value(),远离微软专有的OPENXML()及其同伴API。

看看这个。
