Microsoft.Web.XmlTransform.XmlNodeException: No element in the source document matches about fatantelope HOT 8 OPEN

when I remove the namespace from base.xml ,

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <appSettings>
    <add key="test20180421" value="1" />
     <add key="test20180422" value="2" />
  </appSettings>
</configuration>

then the patch generated as following

<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
  <appSettings>
    <add key="test20180423" value="3" xdt:Transform="InsertBefore(/configuration/appSettings/add[(@key='test20180422')])" />
  </appSettings>
</configuration>

and there is no problem to apply source.

I am not sure if this is a bug in this repository or just bug from Microsoft.Web.Xdt.
I have opened an issue here.

Hi @chucklu

Unfortunately, I wasn't able to reproduce the error you described. It could be related to the version of Microsoft.Web.Xdt being used.

I did however get a different error when I pasted your example into https://fatantelopetester.apphb.com to generate a patch. The error was related to the XML namespace on the node in base.xml: xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0"

I removed the namespace and generated a patch, and then applied the patch using the FatAntelope.exe command line tool, and it correctly applied the patch.

So I suggest removing the XML namespace and trying again as it might be reason for the issue.

Cheers,

Hi @CameronWills ,
The version of Microsoft.Web.Xdt I used is latest version 2.1.2. I also tried the version you used 2.1.1 .
Both of them have the same problem.

The workaround about remove the namespace I have found that, but that's weird.

What's the different error you got?

Actually I can encounter the same exception everytime.
When you try with the provide base.xml and target.xml, could you paste the patch.xml generated?

I know this is quite old. I've picked up this and I'm encountering the same problem. Though in my case it's
No element in the source document matches '/configuration/runtime/assemblyBinding/dependentAssembly[4]'

I'm not sure why it's occurring since XPath supports this syntax. Changing the index to a lower or higher number doesn't change the error. Updated the XDT nuget to 3.1.1 but no luck there either.

To get around this, instead of calling "InsertAfter(xyz)", I changed it to just "Insert". This solves my problem but means that I have to manually check my transformations to avoid this occurring during deployments.

@agility-matth Finally I give up to upgrade the config file through the library, because there are some custom setting in client's config file.
I just upgrade it by linq to xml, operate the xml node one by one programmatically.

@agility-matth are you able to provide the source & target files? Or at least just the /configuration/runtime/assemblyBinding sections of both files? Obviously remove anything sensitive from the files. Thanks

Sure thing @CameronWills , I'll see what I can do early next week and send it over.
