Replace values in XML string with less than descriptive path - sql

Question

I have a very large xml field inside of a SQL Database that I have to edit regularly. I wrote the following Query to change that code which was easy following the xml path to get to what needed changed.
However I found more things further down in SQL that needs altered and I can not figure out the xml path to edit to make that change.
I've been utilizing the following Query to change just the username
DECLARE #config_xml2 xml
select #config_xml2 = configuration_xml from tblDatafeed where datafeed_name = 'DatafeedName' update tbldatafeed
set configuration_xml.modify('replace value of (//*:NetworkCredentialWrapper/#UserName)[1] with sql:variable("#LOGIN")') where datafeed_name ='DataFeedName'
Which is used to change the Username in the following:
<Tokens>
<Token name="DataFileDirectoryName" />
<Token name="DataFileName" />
<Token name="DataFileExtension" />
<Token name="LastRunTime" />
<Token name="LastFileProcessed" />
</Tokens>

But now I need to alter a string that a lot more complex and I am not sure my xml location is right. I have tried using //*NewSourceName1/#Calculation but it doesnt seem work:
Line of code Here I am trying to edit:
<xs:element name="NewSourceName1" type="xs:string" nillable="true" c:Name="Dashboard_Instance_Name" c:Calculation="=STATIC(&quot;MYSTRINGOFTEXTHERE&quot;)" dfm:SimpleFieldType="StaticText" />
Full xml it falls under

Hopeful out come (Look for MYSTRINGOFTEXTHERE or if I could just edit all of =STATIC("MYSTRINGOFTEXTHERE")):
<xs:element name="NewSourceName1" type="xs:string" nillable="true" c:Name="Dashboard_Instance_Name" c:Calculation="=STATIC(&quot;MYSTRINGOFTEXTHERE&quot;)" dfm:SimpleFieldType="StaticText" />
What I tried that didn't work
DECLARE #config_xml2 xml
select #config_xml2 = configuration_xml from tblDatafeed where datafeed_name = 'DatafeedName' update tbldatafeed
set configuration_xml.modify('replace value of (//*:NewSourceName1/#Calculation)[1] with sql:variable("#CoolVariableName")') where datafeed_name ='DataFeedName'
Any help would be greatly appreciated.

Answer 1

The XPath expression was completely off, so I adjusted it.
In XML, there are only five built-in character entities: <, >, &, " and &apos; for <, >, &, " and ' respectively. I replaced them with their literals. Please try the following.
SQL
DECLARE #tbl TABLE (id int IDENTITY PRIMARY KEY, configuration_xml XML);
INSERT INTO #tbl (configuration_xml)
VALUES
(N'<Action>
