How to send xml datas?

Hi.
I’m trying to send an xml request,by using the http-request node. But I’m alway receiving errors from the other server. I might be using the wrong way to send the request. Can someone help ?

Here is the error!

Hi @Kienou_Nestor, I am sorry you’re having trouble. It seems the server is complaining about your XML being invalid. Could you confirm the data structure you are sending? You can redact the actual values, but it’d be important to see the actual structure to identify any problems with it.
