XmlException: Unexpected DTD declaration. Line 1, position 3.

jianzgao — Thu, 14 Dec 2023 09:18:07 GMT

When I try to use below code to test the API search:

But failed, get the error message:
XmlException: Unexpected DTD declaration. Line 1, position 3.

Question:
int this line: new Namespace(user: "nobody", app: "search")
how to define the "user" and "app" parameters value?

I try to use this way:
var service = new Service(new Uri("https://www.splunk.com"));
but still failed and got the same error message.

@jianzgao - I think you are using C# SDK for Splunk.

Splunk has made that SDK deprecated - https://github.com/splunk/splunk-sdk-csharp-pcl

I would recommend using either Python SDK (https://github.com/splunk/splunk-sdk-python ) or Java SDK (https://github.com/splunk/splunk-sdk-java ) or Javascript SDK (https://github.com/splunk/splunk-sdk-javascript )

I hope this helps!!!

@VatsalJagani Thank you for your quick reply.

But as a .net platform soft engine, I would like perfer to use the C# SDK. I feel so confuse why deprecate the C# SDK.
We plan to use C# SDK of splunk to implement some new features.
Seem like we have to change the solution.

Thank you again.

@jianzgao - If you are just starting to work on a new solution, I won't recommend using C# as its been no changes to that for a long time. So you would have to end-up maintaining the library yourself, fixing all the issues similar to this one.

I have personally used Python SDK and its most widely used one if you are comfortable using it.

I hope this helps!!! Kindly upvote if this helps you!!!
