What I have tried:

So far, I have dealt with the creation of XML from the data from the main form (main application) and I know how to read (parsing) the XML response.

I'm not sure why the hosting in IIS requirement - you could use 'Pistache' User's Guide[^] for example. If you need a gateway/front-end, consider using Nginx or similar

My 2 tip:
It sounds like you could take a look at the Windows Web Services API - Win32 apps | Microsoft Docs[^].

Since you are mentioning IIS, I can only assume that you are running you software on Windows.

You should probably not mix IIS and VCL forms ...

The first problem I encountered was how to display the XML file in memo and treeview components.
I found such a piece of code on the web

FILE * stream;
  char FirstLine [512];

  OpenDialog1-> Options.Clear ();
  OpenDialog1-> Options << ofAllowMultiSelect << ofFileMustExist;
  OpenDialog1-> Filter = "Text files (* .txt) | * .txt | All files (*. *) | *. *";
  OpenDialog1-> FilterIndex = 2; // start the dialog showing all files
  if (OpenDialog1-> Execute ())
  {
    for (int I = 0; I <OpenDialog1-> Files-> Count; I ++)
    {
      stream = fopen (AnsiString (OpenDialog1-> Files-> Strings [I]). c_str (), "r");
      if (stream)
      {
        // read the first line from the file
        fgets (FirstLine, sizeof (FirstLine), stream);
        Memo1-> Lines-> Append (firstLine);
        fclose (stream);
      }
    }
  }

At the beginning I wanted to display the file in memo and something is displayed but.
First of all, the file is not AnsiString but UTF-8 and secondly, only the first line is displayed in my memo (according to what is written in the code).
You can help because I'm out of ideas.
