I have the following XML stored in a XML column of a table:
WITH XMLNAMESPACES (DEFAULT 'urn:www:bebe:de:b2b:v01')
SELECT
d.p.value('./Identification[1]', 'BIGINT') AS [Identification]
,d.p.value('./StatusType[1]', 'NVARCHAR(100)') AS [StatusType]
,d.p.value('(./StatusType/@listAgencyIdentifier)[1]', 'int') AS [ListAgencyIdentifier]
,d.p.value('./OriginalDocument[1]', 'BIGINT') AS [OriginalDocument]
FROM [yourtable] [t]
CROSS APPLY [t].[yourcolumn].nodes('//PayloadResponseEvent') AS d(p)
