Use of xml.modify from nested XML - SSRS Subscription Table - sql-server

Question

I'm trying to do a bulk update on email addresses stored in the ExtensionSettings columns from the Subscription table in SSRS database.
I'm a bit lost on how to update the TO and CC values from the XML column.
<ParameterValues>
<ParameterValue>
<Name>TO</Name>
<Value>Jon#yahoo.com</Value>
</ParameterValue>
<ParameterValue>
<Name>CC</Name>
<Value>Sarah#yahoo.com</Value>
</ParameterValue>
<ParameterValue>
<Name>BCC</Name>
<Value />
</ParameterValue>
<ParameterValue>
<Name>ReplyTo</Name>
<Value />
</ParameterValue>
<ParameterValue>
<Name>Subject</Name>
<Value>#ReportName was executed at #ExecutionTime</Value>
</ParameterValue>
<ParameterValue>
<Name>Comment</Name>
<Value />
</ParameterValue>
<ParameterValue>
<Name>Priority</Name>
<Value>NORMAL</Value>
</ParameterValue>
<ParameterValue>
<Name>IncludeLink</Name>
<Value>True</Value>
</ParameterValue>
<ParameterValue>
<Name>IncludeReport</Name>
<Value>True</Value>
</ParameterValue>
<ParameterValue>
<Name>RenderFormat</Name>
<Value>MHTML</Value>
</ParameterValue>
</ParameterValues>
I got some reference but still lost

Basically, I just want to update those properties with < Name >TO</ Name> and < Name >CC</ Name> and update the values to "Test#domain.com"
UPDATE user_details
SET ExtensionSettings.modify('replace value of (/ParameterValues/ParameterValue/Value/text()) with "Test#domain.com"')
WHERE SubscriptionID='2B0080DE-14FA-4A3D-8AEF-14A9238E7841'

The XML.modify() method will only allow you to perform a single modification at a time. Since you want to modify two values you need to execute two UDPATE statements:
UPDATE user_details
SET ExtensionSettings.modify('
replace value of (/ParameterValues/ParameterValue[Name/text()="TO"]/Value/text())[1]
with "Test#domain.com"
')
WHERE SubscriptionID='2B0080DE-14FA-4A3D-8AEF-14A9238E7841';
UPDATE user_details
SET ExtensionSettings.modify('
replace value of (/ParameterValues/ParameterValue[Name/text()="CC"]/Value/text())[1]
with "Test#domain.com"
')
WHERE SubscriptionID='2B0080DE-14FA-4A3D-8AEF-14A9238E7841';
Selecting the resultant XML will return:
<ParameterValues>
<ParameterValue>
<Name>TO</Name>
<Value>Test#domain.com</Value>
</ParameterValue>
<ParameterValue>
<Name>CC</Name>
<Value>Test#domain.com</Value>
</ParameterValue>
<ParameterValue>
<Name>BCC</Name>
<Value />
</ParameterValue>
<ParameterValue>
<Name>ReplyTo</Name>
<Value />
</ParameterValue>
<ParameterValue>
<Name>Subject</Name>
<Value>#ReportName was executed at #ExecutionTime</Value>
</ParameterValue>
<ParameterValue>
<Name>Comment</Name>
<Value />
</ParameterValue>
<ParameterValue>
<Name>Priority</Name>
<Value>NORMAL</Value>
</ParameterValue>
<ParameterValue>
<Name>IncludeLink</Name>
<Value>True</Value>
</ParameterValue>
<ParameterValue>
<Name>IncludeReport</Name>
<Value>True</Value>
</ParameterValue>
<ParameterValue>
<Name>RenderFormat</Name>
<Value>MHTML</Value>
</ParameterValue>
</ParameterValues>
