Correct way of using msbuild xmlpoke - xpath

Question

I am trying to set the value for element if the element value matches
"ABB Automation Builder Platform.abpkg"
My script uses xmlpoke as below:
<XmlPoke
Namespaces="<Namespace Prefix='x' Uri='http://www150.abb.com/spaces/DAE-1/ProdDev/Shared%20Documents/40%20DAE%20Installer/Design/XML%20Descriptions/DAEInstaller_Description_StyleSheet' >"
Query="x:ProductUpdate/x:Packages/x:Package[x:FileName='ABB Automation Builder Platform.abpkg']/x:FileHash"
XmlInputPath="Output\update.manifest"
Value="Ajay Vishwakarma"/>
The xml I am trying to modify is below:
<?xml version="1.0" encoding="utf-8"?>
<ProductUpdate xmlns="http://www150.abb.com/spaces/DAE-1/ProdDev/Shared%20Documents/40%20DAE%20Installer/Design/XML%20Descriptions/DAEInstaller_Description_StyleSheet">

XmlPoke task fails to update element value and gives message "Made 0 replacement(s)."
I have also tries passing query like
Query="//x:ProductUpdate/x:Packages/x:Package[x:FileName='ABB Automation Builder Platform.abpkg']/x:FileHash" OR
Query=".//x:ProductUpdate/Packages/Package[FileName='ABB Automation Builder Platform.abpkg']/FileHash"
I want to know if I am doing it the wrong way?
Please note that I don't want to make any changes in the namespace in my xml document.

Answer 1

You're not crazy.
That (hex coded) spaces in the original xml document in the namespace are throwing things off.
I don't have an answer.
But here is a suggestion.
I always use XmlPeek and then "build up" the Query.
<XmlPeek Namespaces="<Namespace Prefix='peanut' Uri='http://www150.abb.com/spaces/DAE-1/ProdDev/Shared%20Documents/40%20DAE%20Installer/Design/XML%20Descriptions/DAEInstaller_Description_StyleSheet'/>"
XmlInputPath=".\MyXmlFile.xml"
Query="//peanut:ProductUpdate">
<Output TaskParameter="Result" ItemName="Peeked" />
</XmlPeek>
<Message Text="#(Peeked)"/>
(Above with the XmlPeek, I have the top level Query "//ProductUpdate".
The Message #(Peeked) will show the xml fragment for there.
Then I can build up the query and see the results....and adjust as necessary. )
Anyway, back to the problem:
So the above will work IF you change the original Xml to be
<ProductUpdate xmlns="http://www150.abb.com/spaces/DAE-1/ProdDev/Shared Documents/40 DAE Installer/Design/XML Descriptions/DAEInstaller_Description_StyleSheet">
<Strings>
But with the original Xml with the the Hex values for the spaces.......the above won't work. :(
Anyway. That stinks. Its almost like the namespace (in the XmlPeek (or Poke) needs to be "double hexed encoded" or something.
Sorry, I gave it the college try.

Answer 2

I think you need to create a valid Namespace element. What you have is the opening tag, and not a self-closed element.
Instead of:
<Namespace Prefix='x'
Uri='http://www150.abb.com/spaces/..../DAEInstaller_Description_StyleSheet'>
You need:
<Namespace Prefix='x'
Uri='http://www150.abb.com/spaces/..../DAEInstaller_Description_StyleSheet'/>
