使用 T-SQL 解析 XML

Question

我正在尝试在 T-SQL 中解析 XML，但不明白如何编写我的代码。

我的 XML 输出：

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:tns="https://api.quinyx.com/soap/FlexForce">

            <externalInfo1 xsi:type="xsd:string" />

        </timepunches>
        <validationErrors xsi:type="SOAP-ENC:Array" SOAP-ENC:arrayType="xsd:string[0]" />
      </return>

XML 存储在我的数据库表中的单个列中。

我尝试了多种方法来获取任何数据，但最终都没有显示任何数据。

甚至不知道从哪里开始说实话。

这是一个 SQL Server 数据库。

这是现有的查询：

select cast( replace(XMLData, '<?xml version="1.0" encoding="UTF-8"?>','') as xml) as XMLData into #temp from [Quniyx].[xmltest] select XMLData.value('return[1]/TimePunch[1]/item[1]/id[1]','int') from #temp

Answer 1

提供的 XML 格式不正确。我不得不调整它。此外，XML 有多个名称空间。其余的都是微不足道的。
