How to get XML element properties in SQL Server - sql-server

Question

I am trying to parse XML data from a SSIS package, and I want to get the XML element property values.
<DTS:Executable xmlns:DTS="www.microsoft.com/SqlServer/Dts" DTS:refId="Package" DTS:CreationDate="9/15/2021 11:38:35 AM" DTS:CreationName="Microsoft.Package" DTS:CreatorComputerName="X" DTS:CreatorName="Y" DTS:DTSID="{5BDDA1D9-F546-47BC-81BB-E29C0E22D5DA}" DTS:ExecutableType="Microsoft.Package" DTS:LastModifiedProductVersion="16.0.694.0" DTS:LocaleID="1033" DTS:ObjectName="Mine" DTS:PackageType="5" DTS:VersionBuild="195" DTS:VersionGUID="{68B021E9-5664-4E2B-A64D-C8B5CAF38316}">
<DTS:Property DTS:Name="PackageFormatVersion">8</DTS:Property>
<DTS:ConnectionManagers>
<DTS:ConnectionManager DTS:refId="Package.ConnectionManagers[A]" DTS:CreationName="OLEDB" DTS:DTSID="{AE299D88-1DB8-48B1-8548-31BE5C2F2721}" DTS:ObjectName="A">
<DTS:PropertyExpression DTS:Name="InitialCatalog">#[User::A]</DTS:PropertyExpression>
<DTS:PropertyExpression DTS:Name="ServerName">#[User::B]</DTS:PropertyExpression>
<DTS:ObjectData>
<DTS:ConnectionManager DTS:Retain="True" DTS:ConnectRetryCount="1" DTS:ConnectRetryInterval="5" DTS:ConnectionString="Data Source=XXX;Initial Catalog=XXX;Provider=SQLNCLI11.1;Integrated Security=SSPI;Auto Translate=False;Application Name=XXXXX;" />
</DTS:ObjectData>
</DTS:ConnectionManager>
</DTS:ConnectionManagers>
</DTS:Executable>
FOR THIS LINE:
<DTS:Property DTS:Name="PackageFormatVersion">8</DTS:Property>
I want to get the Name="PackageFormatVersion" from the Property element.
How do I do this in T-SQL?

Answer 1

Assuming that the XML is a value of a variable.
SQL
DECLARE #xml XML =
N'<DTS:Executable xmlns:DTS="www.microsoft.com/SqlServer/Dts" DTS:refId="Package" DTS:CreationDate="9/15/2021 11:38:35 AM" DTS:CreationName="Microsoft.Package" DTS:CreatorComputerName="X" DTS:CreatorName="Y" DTS:DTSID="{5BDDA1D9-F546-47BC-81BB-E29C0E22D5DA}"
DTS:ExecutableType="Microsoft.Package" DTS:LastModifiedProductVersion="16.0.694.0" DTS:LocaleID="1033" DTS:ObjectName="Mine" DTS:PackageType="5" DTS:VersionBuild="195" DTS:VersionGUID="{68B021E9-5664-4E2B-A64D-C8B5CAF38316}">
<DTS:Property DTS:Name="PackageFormatVersion">8</DTS:Property>
<DTS:ConnectionManagers>
<DTS:ConnectionManager DTS:refId="Package.ConnectionManagers[A]" DTS:CreationName="OLEDB" DTS:DTSID="{AE299D88-1DB8-48B1-8548-31BE5C2F2721}" DTS:ObjectName="A">
<DTS:PropertyExpression DTS:Name="InitialCatalog">#[User::A]</DTS:PropertyExpression>
<DTS:PropertyExpression DTS:Name="ServerName">#[User::B]</DTS:PropertyExpression>
<DTS:ObjectData>
<DTS:ConnectionManager DTS:Retain="True" DTS:ConnectRetryCount="1" DTS:ConnectRetryInterval="5"
DTS:ConnectionString="Data Source=XXX;Initial Catalog=XXX;Provider=SQLNCLI11.1;Integrated Security=SSPI;Auto Translate=False;Application Name=XXXXX;"/>
</DTS:ObjectData>
</DTS:ConnectionManager>
</DTS:ConnectionManagers>
</DTS:Executable>';
;WITH XMLNAMESPACES(DEFAULT 'www.microsoft.com/SqlServer/Dts')
SELECT result = #xml.value('(/Executable/Property/text())[1]', 'INT');
Output
result
8

The ask is for the attribute value. And the catch is that the default namespace doesn't apply to attributes, so you have to add it explicitly.
DECLARE #xml XML =
N'<DTS:Executable xmlns:DTS="www.microsoft.com/SqlServer/Dts" DTS:refId="Package" DTS:CreationDate="9/15/2021 11:38:35 AM" DTS:CreationName="Microsoft.Package" DTS:CreatorComputerName="X" DTS:CreatorName="Y" DTS:DTSID="{5BDDA1D9-F546-47BC-81BB-E29C0E22D5DA}"
DTS:ExecutableType="Microsoft.Package" DTS:LastModifiedProductVersion="16.0.694.0" DTS:LocaleID="1033" DTS:ObjectName="Mine" DTS:PackageType="5" DTS:VersionBuild="195" DTS:VersionGUID="{68B021E9-5664-4E2B-A64D-C8B5CAF38316}">
<DTS:Property DTS:Name="PackageFormatVersion">8</DTS:Property>
<DTS:ConnectionManagers>
<DTS:ConnectionManager DTS:refId="Package.ConnectionManagers[A]" DTS:CreationName="OLEDB" DTS:DTSID="{AE299D88-1DB8-48B1-8548-31BE5C2F2721}" DTS:ObjectName="A">
<DTS:PropertyExpression DTS:Name="InitialCatalog">#[User::A]</DTS:PropertyExpression>
<DTS:PropertyExpression DTS:Name="ServerName">#[User::B]</DTS:PropertyExpression>
<DTS:ObjectData>
<DTS:ConnectionManager DTS:Retain="True" DTS:ConnectRetryCount="1" DTS:ConnectRetryInterval="5"
DTS:ConnectionString="Data Source=XXX;Initial Catalog=XXX;Provider=SQLNCLI11.1;Integrated Security=SSPI;Auto Translate=False;Application Name=XXXXX;"/>
</DTS:ObjectData>
</DTS:ConnectionManager>
</DTS:ConnectionManagers>
</DTS:Executable>';
;WITH XMLNAMESPACES(DEFAULT 'www.microsoft.com/SqlServer/Dts', 'www.microsoft.com/SqlServer/Dts' as DTS)
SELECT result = #xml.value('(/Executable/Property/#DTS:Name)[1]', 'varchar(200)');
