The TDownLoadURL from ExtActns unit can't do anything more than downloading to a file. It's ExecuteTarget method is implemented like that. If I were you, I would use Indy. It's simple:

uses
  IdHTTP;

var
  Client: TIdHTTP;
  Stream: TStream;
begin
  Client := TIdHTTP.Create;
  try
    Stream := TMemoryStream.Create;
    try
      Client.Get(URL, Stream);
      { ← process Stream somehow }
    finally
      Stream.Free;
    end;
  finally
    Client.Free;
  end;
end;
