SQL Server 2008/2012不解析XML Soap

Question

哦，今天是什麼。我試圖解析SQL Server中的某些XML，並且之前已經完成了一些非常龐大的文件，但對於這些文件，我遇到了最大的問題。我實際上是通過XML做了遞歸解析，這樣我就可以正確識別所有節點，所以我知道我並不瘋狂。

我的代碼是這樣的。

DECLARE @XML XMl 

SELECT @XML = xmldata from testing where testingID = 3 

select T.c.value('Legs[1]', 'varchar(100)') as Legs 
/*t.c.value('(PoolId)[1]', 'varchar(100)') as [Pool], 
t.c.value('(./Model/@id)[1]', 'int') ModelID, 
t.c.value('(./Note)[1]', 'varchar(100)') Note, 
t.c.value('(./Part)[1]', 'varchar(15)') Part*/ 
from @xml.nodes('/Envelope/Body/GetEventDetailResponse/EventsResponse/EventDetail/Races/Race/Pools/Pool') as T(c) 

我留下了一些舊的代碼，我知道這些舊的XML文件的工作沒有問題，但評論說出來。

的XML是這個

      <BreakTo>0.1</BreakTo> 
     </EventDetail> 
    </EventsResponse> 
    </GetEventDetailResponse> 

這將是一個比很多在腳本級別寫出一個分析例程更有效。

您必須指定命名空間，就像這樣：

;with xmlnamespaces(
    'http://schemas.xmlsoap.org/soap/envelope/' as s, 
    default 'http://schema.unitedtote.com/ToteLink/2008/06/Program' 
) 
select 
    T.c.value('Legs[1]', 'varchar(100)') as Legs 
from @xml.nodes('s:Envelope/s:Body/GetEventDetailResponse/EventsResponse/EventDetail/Races/Race/Pools/Pool') as T(c)
