Как исправить ошибку синтаксического анализа XML: ссылка на необъявленный префикс пространства имен: «Матрица»

Я пытаюсь прочитать файл XML

Я написал этот скрипт, но я получаю сообщение об ошибке:

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')

Я проверил много ссылок, и все они предлагали использовать xmlns. Я пробовал многие из них, но все они не работали с той же ошибкой.

Ошибка синтаксического анализа XML: ссылка на необъявленный префикс пространства имен: «Клиент».
