Update XML attribute in SQL Server with name spaces

Question

I have a table with xml column 'Data'. my requirement is to change attributes Uri and InstanceName as we promote the code. I wrote below update statements to do the job. When I execute I see 1 Row(s) affected but unfortunately it is not updating anything. Any help will be highly appreciated. Thanks!.

CREATE TABLE [dbo].[Test_TBD](
    [Id] [int] NULL,
    [Data] [xml] NULL
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]

GO   

 WITH XMLNAMESPACES(DEFAULT 'http://www.tech.com/datafeed/dfx/2010/04')
 UPDATE Test_TBD set
Data.modify('replace value of (/DataFeed/Transporter/ArcherWebServiceTransportActivity/@Uri)[1] with "https://arcs-x"');

 UPDATE Test_TBD set
 Data.modify('replace value of (/DataFeed/Transporter/ArcherWebServiceTransportActivity/@InstanceName)[1] with "ARCS-X"');

Here is the sample data in Data column.

'<DataFeed xmlns="http://www.tech.com/datafeed/dfx/2010/04" xmlns:plugin="pluginExtensions" Type="TODO" Guid="TODO" UserAccount="DF_LEAN_PopulateCommentsSubForm" Locale="en-US" DateFormat="" ThousandSeparator="" NegativeSymbol="" DecimalSymbol="" SendingNotifications="false" SendJobStatusNotifications="false" RecipientUserIds="" RecipientGroupIds="" RecipientEmailAddresses="" Name="CI_C11.01_Lean-Lean_Reject Comments_A2A" >
      <Transporter>
        <transporters:ArcherWebServiceTransportActivity xmlns:transporters="clr-namespace:ArcherTech.DataFeed.Activities.Transporters;assembly=ArcherTech.DataFeed" xmlns:out="clr-namespace:ArcherTech.DataFeed;assembly=ArcherTech.DataFeed" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:compModel="clr-namespace:ArcherTech.DataFeed.ComponentModel;assembly=ArcherTech.DataFeed" xmlns:channel="clr-namespace:ArcherTech.DataFeed.Engine.Channel;assembly=ArcherTech.DataFeed" xmlns:engine="clr-namespace:ArcherTech.DataFeed.Engine;assembly=ArcherTech.DataFeed" xmlns:kernel="clr-namespace:ArcherTech.Kernel.Channel;assembly=ArcherTech.Kernel" xmlns="clr-namespace:ArcherTech.DataFeed;assembly=ArcherTech.DataFeed" xmlns:schema="clr-namespace:System.Xml.Schema;assembly=System.Xml" xmlns:xmlLinq="clr-namespace:System.Xml.Linq;assembly=System.Xml" xmlns:domain="clr-namespace:ArcherTech.Common.Domain;assembly=ArcherTech.Common" xmlns:s="clr-namespace:System;assembly=mscorlib" x:Key="transportActivity" SearchType="ReportId" Uri="https://arcs-d" RecordsPerFile="100" ReportID="EC514865-88D5-49CE-A200-7769EC1C2A88" UseWindowsAuth="false" IsWindowsAuthSpecific="false" WindowsAuthUserName="i9XzCczAQ7J2rHwkg6wG9QF8+O9NCYJZP6y5Kzw4be0+cdvUaGu/9+rHuLstU736pnQrRcwmnSIhd6oPKIvnLA==" WindowsAuthPassword="+y0tCAKysxEMSGv1unpHxfg6WjH5XWylgP45P5MLRdQ6+zAdOLSVy7s3KJa3+9j2i83qn8I8K7+1+QBlCJT1E7sLQHWRFOCEdJgXaIr1gWfUEO+7kjuJnZcIEKZJa2wHyqc2Z08J2SKfdCLh7HoLtg==" WindowsAuthDomain="" ProxyName="" ProxyPort="8080" ProxyUsername="" ProxyPassword="" ProxyDomain="" IsProxyActive="False" ProxyOption="None" InstanceName="ARCS-D" TempFileOnSuccessAction="DoNothing" TempFileOnSuccessRenameString="" TempFileOnErrorAction="DoNothing" TempFileOnErrorRenameString="" Transform="{engine:DataFeedBinding Path=Transform}" SessionContext="{engine:DataFeedBinding Path=Session}">

          </transporters:ArcherWebServiceTransportActivity.Credentials>
        </transporters:ArcherWebServiceTransportActivity>
      </Transporter> 
    </DataFeed>'

I have replaced /DataFeed/Transporter/ArcherWebServiceTransportActivity/@Uri with /DataFeed/Transporter/*/@Uri just to verify by selecting all, it is working fine. It may work in this situation, but I would love to select the desired node and update. please suggest what am I missing. Thanks. — redsam

You need to use WITH XMLNAMESPACES in both your update statements and you need to use the namespace
clr-namespace:ArcherTech.DataFeed.Activities.Transporters;assembly=ArcherTech.DataFeed
for the transporters:ArcherWebServiceTransportActivity node.

WITH XMLNAMESPACES(DEFAULT 'http://www.tech.com/datafeed/dfx/2010/04',
                   'clr-namespace:ArcherTech.DataFeed.Activities.Transporters;assembly=ArcherTech.DataFeed' as t)
UPDATE Test_TBD set
Data.modify('replace value of (/DataFeed/Transporter/t:ArcherWebServiceTransportActivity/@Uri)[1] with "https://arcs-x"');

WITH XMLNAMESPACES(DEFAULT 'http://www.tech.com/datafeed/dfx/2010/04',
                   'clr-namespace:ArcherTech.DataFeed.Activities.Transporters;assembly=ArcherTech.DataFeed' as t)
UPDATE Test_TBD set
Data.modify('replace value of (/DataFeed/Transporter/t:ArcherWebServiceTransportActivity/@InstanceName)[1] with "ARCS-X"');

Hi Mikael, this was my approach too. The only point I go in small opposition is the need to use WITH XMLNAMESPACES as there are other solutions too.

Just for completness, as you have found the answer WITH XMLNAMESPACES already, there are other approaches as well (but admittedly I would go with Mikaels suggestion)

DECLARE @xml XML=
'<DataFeed xmlns="http://www.tech.com/datafeed/dfx/2010/04" xmlns:plugin="pluginExtensions" Type="TODO" Guid="TODO" UserAccount="DF_LEAN_PopulateCommentsSubForm" Locale="en-US" DateFormat="" ThousandSeparator="" NegativeSymbol="" DecimalSymbol="" SendingNotifications="false" SendJobStatusNotifications="false" RecipientUserIds="" RecipientGroupIds="" RecipientEmailAddresses="" Name="CI_C11.01_Lean-Lean_Reject Comments_A2A" >
      <Transporter>
        <transporters:ArcherWebServiceTransportActivity xmlns:transporters="clr-namespace:ArcherTech.DataFeed.Activities.Transporters;assembly=ArcherTech.DataFeed" xmlns:out="clr-namespace:ArcherTech.DataFeed;assembly=ArcherTech.DataFeed" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:compModel="clr-namespace:ArcherTech.DataFeed.ComponentModel;assembly=ArcherTech.DataFeed" xmlns:channel="clr-namespace:ArcherTech.DataFeed.Engine.Channel;assembly=ArcherTech.DataFeed" xmlns:engine="clr-namespace:ArcherTech.DataFeed.Engine;assembly=ArcherTech.DataFeed" xmlns:kernel="clr-namespace:ArcherTech.Kernel.Channel;assembly=ArcherTech.Kernel" xmlns="clr-namespace:ArcherTech.DataFeed;assembly=ArcherTech.DataFeed" xmlns:schema="clr-namespace:System.Xml.Schema;assembly=System.Xml" xmlns:xmlLinq="clr-namespace:System.Xml.Linq;assembly=System.Xml" xmlns:domain="clr-namespace:ArcherTech.Common.Domain;assembly=ArcherTech.Common" xmlns:s="clr-namespace:System;assembly=mscorlib" x:Key="transportActivity" SearchType="ReportId" Uri="https://arcs-d" RecordsPerFile="100" ReportID="EC514865-88D5-49CE-A200-7769EC1C2A88" UseWindowsAuth="false" IsWindowsAuthSpecific="false" WindowsAuthUserName="i9XzCczAQ7J2rHwkg6wG9QF8+O9NCYJZP6y5Kzw4be0+cdvUaGu/9+rHuLstU736pnQrRcwmnSIhd6oPKIvnLA==" WindowsAuthPassword="+y0tCAKysxEMSGv1unpHxfg6WjH5XWylgP45P5MLRdQ6+zAdOLSVy7s3KJa3+9j2i83qn8I8K7+1+QBlCJT1E7sLQHWRFOCEdJgXaIr1gWfUEO+7kjuJnZcIEKZJa2wHyqc2Z08J2SKfdCLh7HoLtg==" WindowsAuthDomain="" ProxyName="" ProxyPort="8080" ProxyUsername="" ProxyPassword="" ProxyDomain="" IsProxyActive="False" ProxyOption="None" InstanceName="ARCS-D" TempFileOnSuccessAction="DoNothing" TempFileOnSuccessRenameString="" TempFileOnErrorAction="DoNothing" TempFileOnErrorRenameString="" Transform="{engine:DataFeedBinding Path=Transform}" SessionContext="{engine:DataFeedBinding Path=Session}">

            <NetworkCredentialWrapper UserName="TeSZmI1SqO0eJ0G2nDVU+glFg/9eZfeMppYQnPfbeg8=" Password="Slt4VHqjkYscWyCwZK40QJ7KOQroG9OTKr+RGt9bQjE=" />
          </transporters:ArcherWebServiceTransportActivity.Credentials>
        </transporters:ArcherWebServiceTransportActivity>
      </Transporter> 
    </DataFeed>';


SELECT 'original: ' + @xml.value('(/*:DataFeed/*:Transporter/*:ArcherWebServiceTransportActivity/@Uri)[1]','varchar(max)') + ' / ' + @xml.value('(/*:DataFeed/*:Transporter/*:ArcherWebServiceTransportActivity/@InstanceName)[1]','varchar(max)');

--namespaces declared as part of the XML_DML
SET @xml.modify('declare namespace ns="http://www.tech.com/datafeed/dfx/2010/04";
                 declare namespace t="clr-namespace:ArcherTech.DataFeed.Activities.Transporters;assembly=ArcherTech.DataFeed"; 
                 replace value of (/ns:DataFeed/ns:Transporter/t:ArcherWebServiceTransportActivity/@Uri)[1] with "https://arcs-x"');

--The Uri is changed
SELECT 'declared: ' + @xml.value('(/*:DataFeed/*:Transporter/*:ArcherWebServiceTransportActivity/@Uri)[1]','varchar(max)') + ' / ' + @xml.value('(/*:DataFeed/*:Transporter/*:ArcherWebServiceTransportActivity/@InstanceName)[1]','varchar(max)');

--namespace tricked out with the "*"
SET @xml.modify('replace value of (/*:DataFeed/*:Transporter/*:ArcherWebServiceTransportActivity/@InstanceName)[1] with "ARCS-X"');

--The InstanceName changed
SELECT 'asterisk: ' + @xml.value('(/*:DataFeed/*:Transporter/*:ArcherWebServiceTransportActivity/@Uri)[1]','varchar(max)') + ' / ' + @xml.value('(/*:DataFeed/*:Transporter/*:ArcherWebServiceTransportActivity/@InstanceName)[1]','varchar(max)');
