T-SQL從XML刪除節點

Question

我需要幫助，刪除錯誤節點，其中我使用的是TabID =“ Claim”，使用Sql Server 2012

<ClaimErrors ClaimID="73">
  <Error ErrorMessage="offer timeframe" TabID="Offer" FieldName="PostMarkDate" ErrorType="FrontEnd" NoteID="2" />
  <Error ErrorMessage=" code is not valid" TabID="Claim" FieldName="None" NoteID="3811257" ErrorType="BackEnd Error" />
</ClaimErrors>



declare @XML table (data xml)
INsert into @XML select '<ClaimErrors ClaimID="73"><Error ErrorMessage="offer timeframe" TabID="Offer" FieldName="PostMarkDate" ErrorType="FrontEnd" NoteID="2" />
<Error ErrorMessage="code is not valid" TabID="Claim" FieldName="None" NoteID="3811257" ErrorType="BackEnd" /></ClaimErrors>'
update @XML set  data.modify('delete //ClaimErrors/Error[text()][contains(.,"TabID=Claim")]')

我正在使用data.modify（'delete // ClaimErrors / Error /但沒有希望。

任何幫助將不勝感激..謝謝

declare @XML table (data xml)
INsert into @XML select '<ClaimErrors ClaimID="73"><Error ErrorMessage="offer timeframe" TabID="Offer" FieldName="PostMarkDate" ErrorType="FrontEnd" NoteID="2" />
<Error ErrorMessage="code is not valid" TabID="Claim" FieldName="None" NoteID="3811257" ErrorType="BackEnd" /></ClaimErrors>'
declare @var nvarchar(256)= 'Claim'
update @XML set  data.modify('delete (/ClaimErrors/Error[@TabID=sql:variable("@var")])[1]')
select data from @XML
