SQL Server中根据xml记录中的属性选择语句为varchar

Question

我有一个包含 2 列、 ID (Int)和ResponseData (Varchar(MAX))的表，我在其中存储了 XML 文本，如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<soapTest:Response xmlns:soapTest="urn:oasis:names:tc:SAML:2.0:protocol" xmlns:xs="http://www.w3.org/2001/XMLSchema" Version="2.0">
   <soap:Issuer xmlns:soap="urn:oasis:names:tc:SAML:2.0:assertion">https://abc.sa/</soap:Issuer>
   <soapTest:Status>
      <soapTest:StatusCode Value="urn:oasis:names:tc:SAML:2.0:status:Success" />
   </soapTest:Status>
   <soap:Assertion xmlns:soap="urn:oasis:names:tc:SAML:2.0:assertion" Version="2.0">
      <soap:AttributeStatement>
         <soap:Attribute Name="http://abc/xxx/englishFirstName" NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:basic">
            <soap:AttributeValue xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="xs:string">JACK</soap:AttributeValue>
         </soap:Attribute>
     <soap:Attribute Name="http://abc/xxx/englishName" NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:basic">
            <soap:AttributeValue xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="xs:string">Jack Mike</soap:AttributeValue>
         </soap:Attribute>
         <soap:Attribute Name="http://abc/xxx/lang" NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:basic">
            <soap:AttributeValue xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="xs:string">en</soap:AttributeValue>
         </soap:Attribute>
         <soap:Attribute Name="http://abc/xxx/dob" NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:basic">
            <soap:AttributeValue xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="xs:string">Thu Jan 21 00:00:00 AST 1988</soap:AttributeValue>
         </soap:Attribute>
         <soap:Attribute Name="http://abc/xxx/userid" NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:basic">
            <soap:AttributeValue xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="xs:string">1010026175</soap:AttributeValue>
         </soap:Attribute>
         <soap:Attribute Name="http://abc/xxx/nationality" NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:basic">
            <soap:AttributeValue xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="xs:string">Canadian</soap:AttributeValue>
         </soap:Attribute>
         <soap:Attribute Name="http://abc/xxx/englishGrandFatherName" NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:basic">
            <soap:AttributeValue xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="xs:string">test</soap:AttributeValue>
         </soap:Attribute>
      </soap:AttributeStatement>
   </soap:Assertion>
</soapTest:Response>

现在我在表中有 100 多条记录，一些响应/xml 记录没有带有属性“Name= http://abc/xxx/englishName ”的标记/节点“属性”，我该如何返回所有这些记录没有这个节点？

例如

第一条记录具有以下标签/属性：

<soap:Attribute Name="http://abc/xxx/englishName" NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:basic">
 <soap:AttributeValue xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="xs:string">Jack Mike</soap:AttributeValue>
     </soap:Attribute>

第二条记录没有它，响应没有属性 Name englishName...

我想用它的 ID 返回所有记录以知道哪个没有这个属性，结果是

ID                    responseData
---------------------------------------------------------------
12                    <?xml version="1.0" encodxxxxxxxx
15                    <?xml version="1.0" encodxxxxxxxx
87                    <?xml version="1.0" encodxxxxxxxx

基于模糊的要求，请尝试以下操作。

SQL

-- DDL and sample data population, start
DECLARE @tbl TABLE (ID INT IDENTITY(1,1) PRIMARY KEY, ResponseData NVARCHAR(MAX));
INSERT INTO @tbl
VALUES (N'<soapTest:Response xmlns:soapTest="urn:oasis:names:tc:SAML:2.0:protocol"
